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

Was the original backup  multiplexed?

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.
