Re: Backup toooo slow.
Sorry guys, I repeat my question with valid information.
What are the reasons for slow data backup. Process usually locks-up the
whole system. I've checked everything I know. But still have slow backup
process. We have tried both on tape and disk devices. Also ontape and
onbar does not make any difference.

Hello Gursoy,
How long takes your backup ?
We use ontape and need for 11 GB Data on a UNIX/AIX 2 1/2 hours for backup
an LEVEL 0 Archive.

What environment are you running in ? Do you have any figures for the restore ?
Many thanks
