Happy Winter Solstice everyone! The Mayan calendar flipped over yesterday, and everything continued as normal.
The next date to watch out for is ... drumroll please ... April 8, 2014. This is the date Microsoft has decided to [drop support for Windows XP].
While many large corporations are actively planning to get off Windows XP, there are still many homes and individuals that are running on this platform.
When [Windows XP] was introduced in 2001, it could support systems with as little as 64MB of RAM. Nowadays, the latest versions of Windows now requires a minimum of 1GB for 32-bit systems, with 2GB or 3GB recommended.
That leaves Windows XP users on older hardware few choices:
- Continue to run Windows XP, but without support (and hope for the best)
- Upgrade their hardware with more RAM (and possibly more disk space) needed to run a newer level of Windows
- Install a different operating system like Linux
- Put the hardware in the recycle bin, and buy a new computer
Here is a personal example. A long time ago, I gave my sister a Thinkpad R31 laptop so that she could work from home. When she got a newer one, she passed this down to her daughter for doing homework. When my neice got a newer one, she passed this old laptop to her grandma.
Grandma is fairly happy with her modern PC running Windows XP. She plays all kinds of games, scans photographs, sends emails, listens to music on iTunes, and even uses Skype to talk to relatives. Her problem is that this PC is located upstairs, in her bedroom, and she wanted something portable that she could play music downstairs when she is playing cards with her friends.
"Why not use the laptop you have?" I asked. Her response: "It runs very slow. Perhaps it has a virus. Can you fix that?" I was up for the challenge, so I agreed.
(The Challenge: Update the Thinkpad R31 so that grandma can simply turn it on, launch iTunes or similar application, and just press a "play" button to listen to her music. It will be plugged in to an electrical outlet wherever she takes it, and she already has her collection of MP3 music files. My hope is to have something that is (a) simple to use, (b) starts up quickly, and (c) will not require a lot of on-going maintenance issues.)
Here are the relevant specifications of the Thinkpad R31 laptop:
|CPU||Intel Celeron 1.13GHz Pentium-III|
|Display||13.3-inch TFT, 1024x768 XGA|
|Memory (RAM)||384 MB @133MHz, upgradeable only to 1GB|
|Disk storage||20.0 GB|
|Optical Drive||CD-ROM drive|
|BIOS boot options||Hard drive or CD-ROM only|
|External attachment||2 USB ports, but no USB boot option|
|Network||Wired 10/100 Mbps Ethernet|
56 Kbps Phone modem
The system was pre-installed with Windows XP, but was terribly down-level. I updated to Windows XP SP3 level, downloaded the latest anti-virus signatures, and installed iTunes. A full scan found no viruses. All this software takes up 14GB, leaving less than 6GB for MP3 music files.
The time it took from hitting the "Power-on" button to hearing the first note of music was over 14 minutes! Unacceptable!
If you can suggest what my next steps should be, please comment below or send me an email!

Since so many personal and corporate users are still on [Windows XP], Microsoft announced that it would provide [Extended Support until 2014]. A ComputerWorld article back in 2007 offered tips on [How to make Windows XP last for the next seven years]. From May 2009 to April 2014, all support is fee-based and non-security hotfixes are produced only for corporate customers.
If we have learned anything from last decade's Y2K crisis, is that we should not wait for the last minute to take action. Now is the time to start thinking about weaning ourselves off Windows XP. IBM has 400,000 employees, so this is not a trivial matter.
Already, IBM has taken some bold steps:
Last July, IBM announced that it was switching from Internet Explorer (IE6) to [Mozilla Firefox as its standard browser]. IBM has been contributing to this open source project for years, including support for open standards, and to make it [more accessible to handicapped employees with visual and motor impairments]. I use Firefox already on Windows, Mac and Linux, so there was no learning curve for me. Before this announcement, if some web-based application did not work on Firefox, our Helpdesk told us to switch back to Internet Explorer. Those days are over. Now, if a web-based application doesn't work on Firefox, we either stop using it, or it gets fixed.
IBM also announced the latest [IBM Lotus Symphony 3] software, which replaces Microsoft Office for Powerpoint, Excel and Word applications. Symphony also works across Mac, Windows and Linux. It is based on the OpenOffice open source project, and handles open-standard document formats (ODF). Support for Microsoft Office 2003 will also run out in the year 2014, so moving off proprietary formats to open standards makes sense.
I am not going to wait for IBM to decide how to proceed next, so I am starting my own migrations. In my case, I need to do it twice, on my IBM-provided laptop as well as my personal PC at home.
- IBM-provided laptop
Last summer, IBM sent me a new laptop, we get a new one every 3-4 years. It was pre-installed with Windows XP, but powerful enough to run a 64-bit operating system in the future. Here are my series of blog posts on that:
I decided to try out Red Hat Enterprise Linux 6.1 with its KVM-based Red Hat Enterprise Virtualization to run Windows XP as a guest OS. I will try to run as much as I can on native Linux, but will have Windows XP guest as a next option, and if that still doesn't work, reboot the system in native Windows XP mode.
Here's is how I have configured my laptop:
|/dev/sda1||35GB||NTFS||C:||Windows XP SP3 operating system and programs|
|/dev/sda2||15GB||ext4||/(root)||Ubuntu Desktop 10.10, SystemRescueCD, Clonezilla, Parted Magic|
|/dev/sda3||55GB||ext4||/(root)||RHEL 6.1 with KVM to run Windows XP as guest OS|
|/dev/sda6||130GB||NTFS||D:||My Documents, Lotus Notes and other data|
|/dev/sda7||70GB||NTFS||E:||Extras and Archives|
Basically, this is a multi-boot system. I use Ubuntu to hold all my Linux utilities, including [SystemRescueCD], [Clonezilla], and [Parted Magic]. The new [Grub2 loader] makes this easy.
Here is what my initial boot screen looks like:
So far, I am pleased that I can do nearly everything my job requires natively in Red Hat Linux, including accessing my Lotus Notes for email and databases, edit and present documents with Lotus Symphony, and so on. I have made RHEL 6.1 my default when I boot up. Setting up Windows XP under KVM was relatively simple, involving an 8-line shell script and 54-line XML file. Here is what I have encountered:
- We use a wonderful tool called "iSpring Pro" which merges Powerpoint slides with voice recordings for each page into a Shockwave Flash video. I have not yet found a Linux equivalent for this yet.
- To avoid having to duplicate files between systems, I use instead symbolic links. For example, my Lotus Notes local email repository sits on D: drive, but I can access it directly with a link from /home/tpearson/notes/data.
- While my native Ubuntu and RHEL Linux can access my C:, D: and E: drives in native NTFS file system format, the irony is that my Windows XP guest OS under KVM cannot. This means moving something from NTFS over to Ext4, just so that I can access it from the Windows XP guest application.
- For whatever reason, "Password Safe" did not run on the Windows XP guest. I launch it, but it takes forever to load and never brings up the GUI. Fortunately, there is a Linux version [MyPasswordSafe] that seems to work just fine to keep track of all my passwords.
- Personal home PC
My Windows XP system at home gave up the ghost last month, so I bought a new system with Windows 7 Professional, quad-core Intel processor and 6GB of memory. There are [various editions of Windows 7], but I chose Windows 7 Professional to support running Windows XP as a guest image.
Here's is how I have configured my personal computer:
|/dev/sda1||104MB||NTFS||C:||Windows 7 Loader|
|/dev/sda2||10GB||ext4||/(root)||Ubuntu Desktop 10.10, SystemRescueCD, Clonezilla, Parted Magic|
|/dev/sda6||60GB||NTFS||C:||Windows 7 OS and programs|
|/dev/sda7||230GB||NTFS||D:||My Documents, Lotus Notes and other data|
|/dev/sda8||250GB||NTFS||E:||Extras and Archives|
I actually found it more time-consuming to implement the "Virtual PC" feature of Windows 7 to get Windows XP mode working than KVM on Red Hat Linux. I am amazed how many of my Windows XP programs DO NOT RUN AT ALL natively on Windows 7. I now have native 64-bit versions of Lotus Notes and Symphony 3, which will do well enough for me for now.
I went ahead and put Red Hat Linux on my home system as well, but since I have Windows XP running as a guest under Windows 7, no need to duplicate KVM setup there. At least if I have problems with Windows 7, I can reboot in RHEL6 Linux at home and use that for Linux-native applications.
Hopefully, this will position me well in case IBM decides to either go with Windows 7 or Linux as the replacement OS for Windows XP.

Continuing my rant from Monday's post [Time for a New Laptop], I got my new laptop Wednesday afternoon. I was hoping the transition would be quick, but that was not the case. Here were my initial steps prior to connecting my two laptops together for the big file transfer:
- Document what my old workstation has
Back in 2007, I wrote a blog post on how to [Separate Programs from Data]. I have since added a Linux partition for dual-boot on my ThinkPad T60.
|/dev/sda1||26GB||NTFS||C:||Windows XP SP3 operating system and programs|
|/dev/sda2||12GB||ext3||/(root)||Red Hat Enterprise Linux 5.4|
|/dev/sda6||80GB||NTFS||D:||My Documents and other data|
I also created a spreadsheet of all my tools, utilities and applications. I combined and deduplicated the list from the following sources:
- Control Panel -> Add/Remove programs
- C:\Program Files
- Start -> Programs panels
- Program taskbar at bottom of screen
The last one was critical. Over the years, I have gotten in the habit of saving those ZIP or EXE files that self-install programs into a separate directory, D:/Install-Files, so that if I had to unintsall an application, due to conflicts or compatability issues, I could re-install it without having to download them again.
So, I have a total of 134 applications, which I have put into the following rough categories:
- AV - editing and manipulating audio, video or graphics
- Files - backup, copy or manipulate disks, files and file systems
- Browser - Internet Explorer, Firefox, Opera and Google Chrome
- Communications - Lotus Notes and Lotus Sametime
- Connect - programs to connect to different Web and Wi-Fi services
- Demo - programs I demonstrate to clients at briefings
- Drivers - attach or sync to external devices, cell phones, PDAs
- Games - not much here, the basic solitaire, mindsweeper and pinball
- Help Desk - programs to diagnose, test and gather system information
- Projects - special projects like Second Life or Lego Mindstorms
- Lookup - programs to lookup information, like American Airlines TravelDesk
- Meeting - I have FIVE different webinar conferencing tools
- Office - presentations, spreadsheets and documents
- Platform - Java, Adobe Air and other application runtime environments
- Player - do I really need SIXTEEN different audio/video players?
- Printer - print drivers and printer management software
- Scanners - programs that scan for viruses, malware and adware
- Tools - calculators, configurators, sizing tools, and estimators
- Uploaders - programs to upload photos or files to various Web services
- Backup my new workstation
My new ThinkPad T410 has a dual-core i5 64-bit Intel processor, so I burned a 64-bit version of [Clonezilla LiveCD] and booted the new system with that. The new system has the following configuration:
|/dev/sda1||320GB||NTFS||C:||Windows XP SP3 operating system, programs and data|
There were only 14.4GB of data, it took 10 minutes to backup to an external USB disk. I ran it twice: first, using the option to dump the entire disk, and the second to dump the selected partition. The results were roughly the same.
- Run Workstation Setup Wizard
The Workstation Setup Wizard asks for all the pertinent location information, time zone, userid/password, needed to complete the installation.
- Re-Partition Disk Drive
I burned a 64-bit version of [System Rescue CD] and ran [Gparted] to re-partition this disk into the following:
|/dev/sda1||40GB||NTFS||C:||Windows XP SP3 operating system and programs|
|/dev/sda2||15GB||ext3||/(root)||Ubuntu Desktop 10.04 LTS|
|/dev/sda6||245GB||NTFS||D:||My Documents and other data|
- Redefine Windows directory structure
I made two small changes to connect C: to D: drive.
- Changed "My Documents" to point to D:\Documents which will move the files over from C: to D: to accomodate its new target location. See [Microsoft procedure] for details.
- Edited C:\notes\notes.ini to point to D:\notes\data to store all the local replicas of my email and databases.
- Install Ubuntu Desktop 10.04 LTS
My plan is to run Windows and Linux guests through virtualization. I decided to try out Ubuntu Desktop 10.04 LTS, affectionately known as Lucid Lynx, which can support a variety of different virtualization tools, including KVM, VirtualBox-OSE and Xen. I have two identical 15GB partitions (sda2 and sda3) that I can use to hold two different systems, or one can be a subdirectory of the other. For now, I'll leave sda3 empty.
- Take another backup of my new workstation
I took a fresh new backup of paritions (sda1, sda2, sda6) with Clonezilla.
The next step involved a cross-over Ethernet cable, which I don't have. So that will have to wait until Thursday morning.

Well, it's Tuesday again, but this time, today we had our third big storage launch of 2009! A lot got announced today as part of IBM's big "Dynamic Infrastructure" marketing campaign. I will just focus on the
disk-related announcements today:
- IBM System Storage DS8700
IBM adds a new model to its DS8000 series with the
[IBM System Storage DS8700]. Earlier this month, fellow blogger and arch-nemesis Barry Burke from EMC posted [R.I.P DS8300] on this mistaken assumption that the new DS8700 meant that DS8300 was going away, or that anyone who bought a DS8300 recently would be out of luck. Obviously, I could not respond until today's announcement, as the last thing I want to do is lose my job disclosing confidential information. BarryB is wrong on both counts:
- IBM will continue to sell the DS8100 and DS8300, in addition to the new DS8700.
- Clients can upgrade their existing DS8100 or DS8300 systems to DS8700.
BarryB's latest post [What's In a Name - DS8700] is fair game, given all the fun and ridicule everyone had at his expense over EMC's "V-Max" name.
So the DS8700 is new hardware with only 4 percent new software. On the hardware side, it uses faster POWER6 processors instead of POWER5+, has faster PCI-e buses instead of the RIO-G loops, and faster four-port device adapters (DAs) for added bandwidth between cache and drives. The DS8700 can be ordered as a single-frame dual 2-way that supports up to 128 drives and 128GB of cache, or as a dual 4-way, consisting of one primary frame, and up to four expansion frames, with up to 384GB of cache and 1024 drives.
Not mentioned explicitly in the announcements were the things the DS8700 does not support:
- ESCON attachment - Now that FICON is well-established for the mainframe market, there is no need to support the slower, bulkier ESCON options. This greatly reduced testing effort. The 2-way DS8700 can support up to 16 four-port FICON/FCP host adapters, and the 4-way can support up to 32 host adapters, for a maximum of 128 ports. The FICON/FCP host adapter ports can auto-negotiate between 4Gbps, 2Gbps and 1Gbps as needed.
- LPAR mode - When IBM and HDS introduced LPAR mode back in 2004, it sounded like a great idea the engineers came up with. Most other major vendors followed our lead to offer similar "partitioning". However, it turned out to be what we call in the storage biz a "selling apple" not a "buying apple". In other words, something the salesman can offer as a differentiating feature, but that few clients actually use. It turned out that supporting both LPAR and non-LPAR modes merely doubled the testing effort, so IBM got rid of it for the DS8700.
Update: I have been reminded that both IBM and HDS delivered LPAR mode within a month of each other back in 2004, so it was wrong for me to imply that HDS followed IBM's lead when obviously development happened in both companies for the most part concurrently prior to that. EMC was late to the "partition" party, but who's keeping track?
Initial performance tests show up to 50 percent improvement for random workloads, and up to 150 percent improvement for sequential workloads, and up to 60 percent improvement in background data movement for FlashCopy functions. The results varied slightly between Fixed Block (FB) LUNs and Count-Key-Data (CKD) volumes, and I hope to see some SPC-1 and SPC-2 benchmark numbers published soon.
The DS8700 is compatible for Metro Mirror, Global Mirror, and Metro/Global Mirror with the rest of the DS8000 series, as well as the ESS model 750, ESS model 800 and DS6000 series.
- New 600GB FC and FDE drives
IBM now offers [600GB drives] for the DS4700 and DS5020 disk systems, as well as the EXP520 and EXP810 expansion drawers. In each case, we are able to pack up to 16 drives into a 3U enclosure.
Personally, I think the DS5020 should have been given a DS4xxx designation, as it resembles the DS4700
more than the other models of the DS5000 series. Back in 2006-2007, I was the marketing strategist for IBM System Storage product line, and part of my job involved all of the meetings to name or rename products. Mostly I gave reasons why products should NOT be renamed, and why it was important to name the products correctly at the beginning.
- IBM System Storage SAN Volume Controller hardware and software
Fellow IBM master inventory Barry Whyte has been covering the latest on the [SVC 2145-CF8 hardware]. IBM put out a press release last week on this, and today is the formal announcement with prices and details. Barry's latest post
[SVC CF8 hardware and SSD in depth] covers just part of the entire
The other part of the announcement was the [SVC 5.1 software] which can be loaded
on earlier SVC models 8F2, 8F4, and 8G4 to gain better performance and functionality.
To avoid confusion on what is hardware machine type/model (2145-CF8 or 2145-8A4) and what is software program (5639-VC5 or 5639-VW2), IBM has introduced two new [Solution Offering Identifiers]:
- 5465-028 Standard SAN Volume Controller
- 5465-029 Entry Edition SAN Volume Controller
The latter is designed for smaller deployments, supports only a single SVC node-pair managing up to
150 disk drives, available in Raven Black or Flamingo Pink.
- EXN3000 and EXP5060 Expansion Drawers
IBM offers the [EXN3000 for the IBM N series]. These expansion drawers can pack 24 drives in a 4U enclosure. The drives can either be all-SAS, or all-SATA, supporting 300GB, 450GB, 500GB and 1TB size capacity drives.
The [EXP5060 for the IBM DS5000 series] is a high-density expansion drawer that can pack up to 60 drives into a 4U enclosure. A DS5100 or DS5300
can handle up to eight of these expansion drawers, for a total of 480 drives.
- IBM System Storage Productivity Center v1.4
The latest [System Storage Productivity Center (SSPC) v1.4] can manage all of your DS3000, DS4000, DS5000, DS6000, DS8000 series disk, and SAN Volume Controller. You can get the SSPC built in two modes:
- Pre-installed with Tivoli Storage Productivity Center Basic Edition. Basic Edition can be upgraded with license keys to support Data, Disk and Standard Edition to extend support and functionality to report and manage XIV, N series, and non-IBM disk systems.
- Pre-installed with Tivoli Key Lifecycle Manager (TKLM). This can be used to manage the Full Disk Encryption (FDE) encryption-capable disk drives in the DS8000 and DS5000, as well as LTO and TS1100 series tape drives.
- IBM Tivoli Storage FlashCopy Manager v2.1
The [IBM Tivoli Storage FlashCopy Manager V2.1] replaces two products in one. IBM used
to offer IBM Tivoli Storage Manager for Copy Services (TSM for CS) that protected Windows application data, and IBM Tivoli Storage Manager for Advanced Copy Services (TSM for ACS) that protected AIX application data.
The new product has some excellent advantages. FlashCopy Manager offers application-aware backup of LUNs containing SAP, Oracle, DB2, SQL server and Microsoft Exchange data. It can support IBM DS8000, SVC and XIV point-in-time copy functions, as well as the Volume Shadow Copy Services (VSS) interfaces of the IBM DS5000, DS4000 and DS3000 series disk systems. It is priced by the amount of TB you copy, not on the speed or number of CPU processors inside the server.
Don't let the name fool you. IBM FlashCopy Manager does not require that you use Tivoli Storage Manager (TSM) as your backup product. You can run IBM FlashCopy Manager on its own, and it will manage your FlashCopy target versions on disk, and these can be backed up to tape or another disk using any backup product. However, if you are lucky enough to also be using TSM, then there is optional integration that allows TSM to manage the target copies, move them to tape, inventory them in its DB2 database, and provide complete reporting.
Yup, that's a lot to announce in one day. And this was just the disk-related portion of the launch!

In my last blog post [Full Disk Encryption for Your Laptop] explained my decisions relating to Full-Disk Encryption (FDE) for my laptop. Wrapping up my week's theme of Full-Disk Encryption, I thought I would explain the steps involved to make it happen.
Last April, I switched from running Windows and Linux dual-boot, to one with Linux running as the primary operating system, and Windows running as a Linux KVM guest. I have Full Disk Encryption (FDE) implemented using Linux Unified Key Setup (LUKS).
Here were the steps involved for encrypting my Thinkpad T410:
- Step 0: Backup my System
Long-time readers know how I feel about taking backups. In my blog post [Separating Programs from Data], I emphasized this by calling it "Step 0". I backed up my system three ways:
- Backed up all of my documents and home user directory with IBM Tivoli Storage Manager.
- Backed up all of my files, including programs, bookmarks and operating settings, to an external disk drive (I used rsync for this). If you have a lot of bookmarks on your browser, there are ways to dump these out to a file to load them back in the later step.
- Backed up the entire hard drive using [Clonezilla].
Clonezilla allows me to do a "Bare Machine Recovery" of my laptop back to its original dual-boot state in less than an hour, in case I need to start all over again.
- Step 1: Re-Partition the Drive
"Full Disk Encryption" is a slight misnomer. For external drives, like the Maxtor BlackArmor from Seagate (Thank you Allen!), there is a small unencrypted portion that contains the encryption/decryption software to access the rest of the drive. Internal boot drives for laptops work the same way. I created two partitions:
- A small unencrypted partition (2 GB) to hold the Master Boot Record [MBR], Grand Unified Bootlloader [GRUB], and the /boot directory. Even though there is no sensitive information on this partition, it is still protected the "old way" with the hard-drive password in the BIOS.
- The rest of the drive (318GB) will be one big encrypted Logical Volume Manager [LVM] container, often referred to as a "Physical Volume" in LVM terminology.
Having one big encrypted partition means I only have to enter my ridiculously-long encryption password once during boot-up.
- Step 2: Create Logical Volumes in the LVM container
I create three logical volumes on the encrypted physical container: swap, slash (/) directory, and home (/home). Some might question the logic behind putting swap space on an encrypted container. In theory, swap could contain sensitive information after a system [hybernation]. I separated /home from slash(/) so that in the event I completely fill up my home directory, I can still boot up my system.
- Step 3: Install Linux
Ideally, I would have lifted my Linux partition "as is" for the primary OS, and a Physical-to-Virtual [P2V] conversion of my Windows image for the guest VM. Ha! To get the encryption, it was a lot simpler to just install Linux from scratch, so I did that.
- Step 4: Install Windows guest KVM image
The folks in our "Open Client for Linux" team made this step super-easy. Select Windows XP or Windows 7, and press the "Install" button. This is a fresh install of the Windows operating system onto a 30GB "raw" image file.
TuxRadar has a good [Howto: Linux and Windows virtualization with KVM and Qemu] on this if you are not in IBM. To my surprise, the Windows XP runs better as a KVM guest under Linux than it did running natively in my dual-boot configuration.
(Note: Since my Thinkpad T410 is Intel-based, I had to turn on the 'Intel (R) Virtualization Technology' option in the BIOS!)
There are only a few programs that I need to run on Windows, so I installed them here in this step.
- Step 5: Set up File Sharing between Linux and Windows
In my dual-boot set up, I had a separate "D:" drive that I could access from either Windows or Linux, so that I would only have to store each file once. For this new configuration, all of my files will be in my home directory on Linux, and then shared to the Windows guest via CIFS protocol using [samba].
In theory, I can share any of my Linux directories using this approach, but I decide to only share my home directory. This way, any Windows viruses will not be able to touch my Linux operating system kernels, programs or settings. This makes for a more secure platform.
- Step 6: Transfer all of my files back
Here I used the external drive from "Step 0" to bring my data back to my home directory. This was a good time to re-organize my directory folders and do some [Spring cleaning].
- Step 7: Re-establish my backup routine
Previously in my dual-boot configuration, I was using the TSM backup/archive client on the Windows partition to backup my C: and D: drives. Occasionally I would tar a few of my Linux directories and storage the tarball on D: so that it got included in the backup process. With my new Linux-based system, I switched over to the Linux version of TSM client. I had to re-work the include/exclude list, as the files are different on Linux than Windows.
One of my problems with the dual-boot configuration was that I had to manually boot up in Windows to do the TSM backup, which was disruptive if I was using Linux. With this new scheme, I am always running Linux, and so can run the TSM client any time, 24x7. I made this even better by automatically scheduling the backup every Monday and Thursday at lunch time.
There is no Linux support for my Maxtor BlackArmor external USB drive, but it is simple enough to LUKS-encrypt any regular external USB drive, and rsync files over. In fact, I have a fully running (and encrypted) version of my Linux system that I can boot directly from a 32GB USB memory stick. It has everyting I need except Windows (the "raw" image file didn't fit.)
I can still use Clonezilla to make a "Bare Machine Recovery" version to restore from. However, with the LVM container encrypted, this renders the compression capability worthless, and so takes a lot longer and consumes over 300GB of space on my external disk drive.
Backing up my Windows guest VM is just a matter of copying the "raw" image file to another file for safe keeping. I do this monthly, and keep two previous generations in case I get hit with viruses or "Patch Tuesday" destroys my working Windows image. Each is 30GB in size, so it was a trade-off between the number of versions and the amount of space on my hard drive. TSM backup puts these onto a system far away, for added protection.
- Step 8: Protect your Encryption setup
In addition to backing up your data, there are a few extra things to do for added protection:
- Add a second passphrase. The first one is the ridiculously-long one you memorize faithfully to boot the system every morning. The second one is a ridiculously-longer one that you give to your boss or admin assistant in case you get hit by a bus. In the event that your boss or admin assistant leaves the company, you can easily disable this second passprhase without affecting your original.
- Backup the crypt-header. This is the small section in front that contains your passphrases, so if it gets corrupted, you would not be able to access the rest of your data. Create a backup image file and store it on an encrypted USB memory stick or external drive.
If you are one of the lucky 70,000 IBM employees switching from Windows to Linux this year, Welcome!
