replication and tape backup
|

| If I use replication to make a copy of data at a DR site
how do I create a tape backup off of that for long-term
retention? Short-lived snaps are no problem, they only
live on disk but once every few months I want to write a
tape to capture that point in time for longer retention.
If the DR site only has replicated LUNs how do I do tape
backup for the long-term?
To say it another way if I have N different types of clients
using replicated SAN storage do I have to buy N more clients
for the DR site to mount those volumes as filesystems in
order to run Netbackup?

| The issue you will have to deal with is the number of different file
system types that exist at the DR site.
A Windows 2003 system should be able to handle LUNs from any earlier
version of windows. The same rule would apply to a Linux environment as
well.
If you have a mix of operating systems but they are all running on a
x86 platform then you could consider using a product like VMWare to
create a virtual machine for each OS.
If, however, you have clients with different architectures such as
Windows clients and Apple clients then you will likely need seperate
physical boxes to back up such an environment.

It depends.
OS software? Back up software? Bandwidth between production and DR
site?

| Veritas NetBackup includes in its base product disk staging. You could
create 2 copies from disk or "clones"

Have a look at Bacula <http://www.bacula.org> which backs up an impressive
number of client architectures onto a Unix server.
