LTFS – Linear Tape File System
Enterprise Data protection is not a new topic (it’s actually a core IT principal = protecting data) and we continue to see a growing investment in data protection methodologies in enterprises across the globe. While some of our competition want you to believe that all data needs can be satisfied by placing all data on spinning disk; doesn’t seem very economical to me. Tape is the greenest IT offering to date across the market. We are not going to discuss tape offerings, let us discuss what IBM helped write and released early in 2010. The product offering is called LTFS which stands for Linear Tape File System. This new offering allows admins drag and drop capabilities for files making the tape F/S system appear to be a removable media format (Flash Drive, DVD etc,) to the Operating System. So drag and drop to / from tape seems like an inexpensive solution for Video Surveillance files.
How does LTFS work?
LTFS is a physical media portioning technology and LTFS creates 2 partitions on LTO5 tapes while the schema is stored in XML format.
What Operating Systems are supported?
RHEL 5.4, 5.5, MAC OS X 10.5, Windows 7, and others are getting their stamp of approval.
What Backup Software is supported?
No dedicated backup program such as TSM, NetBackup etc are required as the OS can write directly to the tape itself.
What Hardware is supported?
LTFS V1 supports LTO5 tape drives while the Tape Libraries are gaining their stamp of approval look for that in future releases.LTFS Defaults: Block size is 1MB
Best of all LTFS is FREE, yes that is not a typo it’s free.
