based backup arrived in 2004, and Southborough, MA
-
based
Sepaton Inc.'s S2100
-
ES Virtual
Tape Library (VTL) appliance led
the parade of products that confirmed disk
-
based backup's role in
the data center.
Sepaton's VTL supports both ATA and SATA drives, and emulates
almost any LTO, DLT and AIT tape drive. Scalability isn't much of
an issue a
s the S2100
-
ES uses its own scalable replication engine,
which starts at 3.5TB and can grow to 200TB.
Sepaton says its box is capable of 150MB/sec to 900MB/sec transfer
rates and can back up 1.6TB per hour. "It is incredibly fast, scalable
and uniquely u
nderstands what's in the backups it is receiving," one
judge gushed. "This allows it to create an index of the data and
perform synthetic backups, which simplifies recovery by consolidating incremental backups into
one complete backup."
Synthetic backups
are similar to Tivoli Storage Manager's incremental backups
--
where only
changed data is moved during a full backup. But Sepaton takes this notion a step further.
Because the S2100 knows where and what the backups are with its "content
-
aware architecture,"
it creates a new volume using pointers instead of recreating the data entirely. This method cuts
the time needed for full backups and frees up application servers and the network which, in turn,
leads to faster restores.
The S2100 is certified to work wit
h backup software from BakBone Software Inc., CommVault
Systems Inc., EMC Corp./Legato, IBM Tivoli and Veritas Software Corp.
The starting price for an S2100 is $58,000. Not chump change but, nevertheless, a bargain when
your backup window shrinks an orde
r of magnitude over conventional backup methods. And, yes,
all restores are much quicker as well.
SILVER:
Network Appliance's NearStore R200
Network Appliance (NetApp) Inc.'s NearStore R200 is the first disk
-
based backup product that achieved a critical mass with users.
Shipped in December 2003, our judge
s didn't forget it.
"The NearStore R200 allows the user to take advantage of all of the
wonderful replication capabilities of Network App's snapshot
applications using very low
-
cost disk. They were one of the first, if
not the first, with this technology,
" said one judge.
The R200 comes with a 14
-
drive disk shelf with SATA/FC
-
AL disks
and scales from 8TB to 96TB. Prices start at $7.00/GB for a low
-
end
system, but it's flying out of NetApp's door. According to ESG, NetApp
shipped nearly 35PB of R200 stora
ge since the product's inception.
