Re: [Veritas-bu] Remote Online Backups
2008-03-14 14:52:04
A suggestion I tend to favor for Windows is putting in a
DFS (or similar) solution where by all data as Remote Site A is replicated (bit
by changed bit) back to a DFS in the data center. We're using a
home-grown similar solution for our Linux / Unix replication here.
Come backup time you just grab the local datacenter copy.
Similar to Ed below, we also looked at a Data Domain
appliance (and replication) to de-dupe the data locally then send it across the
wire for backup to tape / keep offsite. The appliance fills the gap Ed
mentions below where a local copy of the data is available, but adding an extra
box (even a "cheap" appliance) would definitely be more expensive than the
Pruedish solution below.

We
have about 40 locations worldwide, with a typical data size of about 200 GB
per location, with some up to 2 TB. Most sites have 1024 to 1536 Kb/s MPLS
links, with a few 2 Mb/s and one 4.5 Mb/s. Central data center has two 45 Mb/s
links. We are looking to remote, online backups to our data center from
each location. I'm wondering which products and processes have
worked.
Has anybody successfully implemented remote, online backups of
Windows servers across their WAN to a central data center?
We're using PureDisk for our remote offices. For smaller offices,
we're backing up directly across the WAN to our central data center. For 1
large site, we have a storage location there with replication do the central
data center. For other sites, we just have a NetBackup media server at the
remote site with a bunch of local disk. For those, we obviously don't care
about DR since the backups are at the same physical site as the source
data.
Contact your friendly Symantec sales rep for a PureDisk

The biggest gotcha with remote backups is not the backups - it's
the restore. You can push a lot of data across a slow line over a long
period, but if somebody takes a double-disk failure in their RAID5 set and wants
to restore 200GB, be prepared to do a restore to a portable USB drive and to
ship that via FedEx/UPS...
