We have actually resolve similar problems buy purchasing Network Appliance
devices. I am not sure what your budget is like but 18mos ago I was looking
for a similar solution. We purchased two Netapp Units one for our remote
office and the other for corporate. Using Netapp's snapmirror technology all
Mission Critical data is replicated to the remote office nightly and data
comes back to corporate from the remote office. It works very well, the most
we have to do is check the logs to make sure replication was successful and
once a quarter we test our DR plan to make sure we can recover the
replicated data.

Subject: [Veritas-bu] Scenarios for remote site backup
We've got remote sites currently configured as independent master servers
with attached small libraries. These sites are connected via thin-pipe WAN
links to our main datacenter. Currently, we don't offsite any tapes or
attempt to transfer the data from these remote sites. This has gotten us
into trouble (two of these centers were affected by the Florida hurricanes,
one's near a fault, one's near a volcano, etc.). We need a more reliable,
ie: no people involved, way of offsiting this data other than trying to
physically remove tapes from the library when the hurricane is approaching.
I'm also spending waaaay to much time calling STK to replace failed tape
drives, remove stuck tapes, etc. I'd like to get rid of all the remote tape
libraries.
An obvious way would be to configure each remote server set as simple
clients from our local centalized library and master server and drag the
backup data across the network. This, unfortunately, is probably too slow
considering the WAN link sizes.
A solution to getting rid of the local tape libraries is backup to a local
disk array. This, however, doesn't solve the offsite problem. NFS mounting
a centralized protected filer as a local disk array would be WAN limited
again.
So - I've got this idea about perhaps backing up to a disk array on the
remote server then either using bpduplicate to create a second copy on a
centralized array or, perhaps, using some sort of filesystem/disk snapshot
technology to duplicate this remote disk array to a protected site. Done
right, it could be changed-blocks only.
Have any of you solved this problem and what are you doing?
