Unfortunately very slow restores is the biggest problem of
The backup is very fast. And the restore of the volume is very
fast. But when you try to restore a file, then you may wait more time than the
time to restore the volume. Netbackup reads the backup serially, to find the

file restore from a raw FlashBackup backup will perform much more slowly than a
restore of the entire partition, and the performance decreases exponentially
the more individual files that are selected for restore. One way to increase
performance is to configure the 'Maximum fragment size' on the Storage Unit to
a small size such as 1GB or even 500MB (prior to the backups of course).

Subject: [Veritas-bu] FlashBackups - Q & A:
fellow member has kindly guided me into the right direction of using
FlashBackps. However I have a few Questions to clarify if poss.
all Windows 2003 SP2 + NBU 6.5.6 - Running Eval License of NBU to open up
have tested the product, and moved the tests into production (to gain full
access to Robot+Drives+San Media Servers).
ran a test on a Network based Client of their E: Drive. It performed the
FlashBackup in 48mins. Looking at the full backup running under the normal
client took 2 hours.
today, I have tried to do a restore of a 1GB folder containing lots of files.
But its taking what appears to be ages. 20 Mins in, and only recovered 300mb so
this sound correct?
when I create a Backup Policy, under the Policy -> Backup Selections Tab I
type in \\.\E: and press return. I get a dialog
box telling me that "The NetBackup Client Service on the client must have
a Log on account specified other than the system account. the account used must
have permission to create directories and files under the UNC path specified.
Do you wish to continues?"
have an account created, and applied this to the NetBackup Client Service and
as I mentioned, it has run. But if I create a brand new policy, add a client in
the Clients Tab, then goto Backup Selections and type in \\. \E: and press
Enter I do not get a pop up message. If you look carefully, I have put a SPACE
after the fullstop! But this seems to go against the NetBackup documentation I
have that does not appear to show a space.
the purpose of this is for some of our large servers that have Multiple
volumes. Is there any problem selecting multiple drive letters under Backup
selections tab? In other words, rather than list 1, can I list 8 different
for the feedback.
