Paul,
We currently run netbackup to push about 1.3PB of real data to tape.
This using 1 nb master and a single media server that is also a GPFS
client. The media server uses the spare file system space as a staging
area before writing to tape. We have recently invested into a TSM
server due to limitations of netbackup. The PVU licensing model makes
TSM cost effective. We simply are not able to speed up the netbackup
catalog even with SSD. You could potentially use the gpfs ilm engine to
create file lists to feed to netbackup.
netbackup (now back to veritas) does not officially support GPFS.
Netbackup is not aware of gpfs metadata.

We have a relatively mature NetBackup environment which handles all of
our tape backup requirements (e.g. databases, NetApp via NDMP, Windows
shares, and native Linux – which provides rudimentary coverage of
GPFS). Because of this existing base, we’re hesitant to invest in a
completely separate infrastructure just for the benefit of GPFS
backups. While this works well for many filesets, it’s not ideal for
very large ones.
We’ve been trying to get Veritas to support a more parallel file-scan
and file-copy approach to backing up GPFS filesystems, and have
repeatedly hit a brick wall there over the past year. But I have a
recent thread in which they note that there is a fairly large and
vocal GPFS customer who drives significant feature flow in their
product. Any chance that customer is a member of the User Group? If
so, I’d love to hear from you.
Thanks,
Paul
