Re: [Veritas-bu] Backing up a SAN

Hi Eric,
We back up our SAN using standard network-based media servers. There
are options like off-host backups that are fully documented in the NetBackup
document set – see the Advanced Client documentation. The basic concept is
that you snapshot the file system, either through the host OS or via the SAN
storage frames, and then mount those volumes up on a media server that writes
directly to tape.
With NetBackup 6.5, you have the option of a “SAN client” which
is essentially a media server client but without tape drivers. This allows
you to access your SAN-based data and write to a SAN-based disk storage unit.
No network traffic is involved except for the catalog data.

Subject: [Veritas-bu] Backing up a SAN
How
do most people back up SAN data with NetBackup? Currently, we have a legacy
setup where the NB client on each SAN-connected host system backs up the SAN
mounts that it sees as a regular file system. Obviously, this is very
inefficient as it puts load on each client and requires additional network
traffic.
I
thought about a media server connected directly to the SAN, but then there are
locking issues with concurrent access to LUNs that are in use by the client
systems.
Can this be done properly without some sort of extra software/hardware
solution?
Eric
