Hello,

check at least folllowing possibly limiting factors:

        - how long does it take to create a backupse (simple test it)
        - is the restore time eventually limited by the speed the old NAS
can
        create files? test it - copy a bunch of small files from a
workstation to NAS
        and look how the copy(=restore) speed is.

regards
Juraj

Betreff: Minimizing Restore Time Using Backupsets


Hello Everyone

I have the (perhaps) crazy idea that having backupsets around can help my
restore time even if they reside on a library controled by the TSM server..
I
have a server with around 400,000 small files and over 150 Gigs. I can't do
Image Backups cause files reside on an old NAS. I have an average backup
trhoughput of about 6 Mb/Sec but restore is not good: 2.2 Mb/Sec. I got the
idea that if I do periodic backupsets and restore from those, even though
they'll be traveling trough the network, restore tiem will decrease.

Is all this real or am I missing something? How do backupsets integrate in
your backup strategy?
