We have Norton Anti-virus running and the disks were changed after the
backup and before the restore from RAID5 to RAID1 and mirrored.

Did you have any anti virus software running - this can substantially
increase your restore times as we have seen the CPU pegged on the client.

Hi
There is the impact of LAN traffic - it can be substantial.
Are the disks RAID5 and either software RAIDED (not on an external disk
subsystem where there is a RAID controller ) or on an old RAID Subsystem.
- if that the case you are encountering RAID5 "write penalty" that will
slow done restores - restore times 3x backups may be too long for the
impact of RAID5 unless the system is old.
A quick test is to ftp a large file/s from client to backup server and send
it back again
Regards
Jim McDonald

Subject: [Veritas-bu] Long Restore times
Hello,
I understood that a Netbackup restore would take about twice as long as
the backup. My experience was 3 times as long to restore. The restore was
the only job running on the server and client. Are there some restore
parameters, I could use to help this process or is
3 times a better ROT?
Backup time 45g in 2 hours 38592 files
Restore time 43g in 6 hours 21405 files
Environment:
Master/media
Sun E450
Solaris 5.8
(3) 400MHz processors
NBU 4.5
L700 - DLT8000 drives
Client
Windows 2000
100mb/full duplex.
Thanks for any information or experiences.
