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

LTFS is a physical media
portioning technology and LTFS creates 2 partitions on LTO5 tapes while the

such as TSM, NetBackup etc are required as the OS can write directly to the
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.

Best of all LTFS is FREE,
yes that is not a typo it’s free.
