This blog is great, and a fantastic resource for someone very new to the storage arena. I have really easy question for you...<div>&nbsp;</div> I have limited knowledge and experience backing up enterprise level systems and I've recently been charged with backing up a 11 TB of sensitive data, with room for growth to 50 TB and more. Taking scalability into consideration, what's my best resource to learn very quickly what I need to know? I don't want some vendor to cajole me into wrapping our financial resources around something that's too small, too large, or too limited.<div>&nbsp;</div> Have any suggestions?<div>&nbsp;</div> In the meantime, I'll keep reading this awesome blog.<div>&nbsp;</div> Thanks!Brandon

Brandon,Yes, very reasonable question. Without knowing the specifics of your situation, operating system, file system, database, or application, I can only point you to general resources. You are welcome to post back with more details, or contact me via e-mail (tpearson@us.ibm.com) if you don't want your details public on this blog.<div>&nbsp;</div> First, learn about IBM Tivoli Storage Manager (TSM). We have a TSM Express and Tivoli CDP for Files for small Windows-only deployments, TSM Standard Edition for medium deployments, and TSM Enterprise Edition for large deployments, with the ability to grow from one to the other. Web site: http://www.ibm.com/software/tivoli/products/storage-mgr/<div>&nbsp;</div> Second, review our IBM Redbooks collection. IMHO, these are the best-written books within IBM, and are written by real people using the products and solutions they are writing about. You can search the library for terms like "Backup", "Tivoli Storage Manager", "Business Continuity" and so on.Web site: http://www.redbooks.ibm.com/<div>&nbsp;</div> Third, you mentioned the data was "sensitive", which implies that the backup copies either need to be on disk, or encrypted tape, to prevent un-encrypted data walking out the door in someones pocket or briefcase. TSM can backup directly to disk systems, virtual tape libraries (VTL) that are actually disk looking like tape such as our IBM System Storage TS7520, and encrypted tape (either our TS1120 or LTO4 drives).<div>&nbsp;</div> Fourth, consider supplementing TSM with advanced copy services available on disk systems. Point-in-Time copies like FlashCopy make instant copies of a disk LUN to another disk LUN. Disk Mirroring like Metro Mirror or Global Mirror send data written to one disk LUN to another at some distance away in real time, keeping them current continuously, rather than one-time copy. These features are available on most of our disk systems: IBM System Storage SAN Volume Controller, DS4000, DS6000, DS8000, and N series.<div>&nbsp;</div> This should get you started. Feel free to contact me, or anyone else in IBM, when you are ready to continue the conversation.<div>&nbsp;</div>
