Disk-to-Disk Backup! As
the proliferation of low cost IDE/ATA RAID solutions continue
to grow and the cost approaches the same per-megabyte as
tape, disk-to-disk backup is becoming a more viable and
affordable solution. Having a hard drive speed near real-time
copy of data, without having to wait on inherently slow
tapes to restore, is paving the way for faster recovery
times between failures, corruption, virus attacks, etc.
Faster recovery times means less down time, minimizing your
risk of loss revenue to your organization.
Unlike NAS, an iSCSI backup is performed at a "block-level"
verses a "file-level". Therefore, an iSCSI backup
is twice as fast as NAS. None of the CPU overhead associated
with "rebuilding" the files are necessary using
the iSCSI method. But most importantly, the restoration
time is performed twice as fast.
Going to the next level, disk-to-disk backup can be performed
over your WAN connection to a remote site for a true disaster
recovery plan.
Also, technologies are in the making that allow for "serverless"
or "extended copy" backups. This is where your
application server would be relieved of the duty (I/O and
CPU cycles) of protecting it's data. Protection of your
data is performed directly from the storage to the hard
drive/tape drive. By doing this, there is no performance
degradation on the server being protected. This leaves all
your server's resources to service your customers, clients
and end-users.
Use simpleSAN's experience
and expertise to help you design a disk-to-disk solution
that will ensure that your mission critical data is allows
protected.
iSCSI, all the availability,
scaleability and manageability benefits of fibre channel SANs
at a fraction of the cost and without the intense learning
curve.

Disk-to-disk backup is a "killer app" for iSCSI.
Backup is a universal problem, and in all the big shops, the
traditional disk-to-tape methodology doesn't work anymore.
Users need to create backups directly onto disk, and then
off to tape. iSCSI disk arrays provide a cheap, simple way
to create an online, real-time recovery methodology at only
a fraction of the cost of traditional primary storage.
By utilizing an iSCSI disk array, users can very inexpensively
solve the backup problem with no real downside, while at the
same time gaining the advantage of dipping their toes into the
storage-over-IP waters.
