Unfortunately, the percentage complete backup bar is about as reliable a Microsoft's file copy bar. You know, the 10 seconds remaining file copy that takes 30 minutes? If you want accurate data you need to open up perfmon and get your KBps there. There are hundreds of things that could cause a backup to slow down. Is this a file server with millions of small files? Did disk utilization go up after hours because of running processes? Have you tried multiple streams versus single stream? If you kick off the backup before going home will it still be 20% in the morning or only 2%? You are going to have to do some investigating.

Good luck!

Hi all,

First of all I am a noob in backup systems.

I am having such a estrange issue with the Veritas NetBackup 6.0:

1. I launch a manual backup of one data server ( about 160Gb )

2. Check the proccess during working hous: every thing OK. It’s backuping as espected.

3. Check before going back home at the last minute of working hours 20% completed.

4. The next day morning at first minute check and see ( 22% completed )

So in 7hours from 8am to 3:00am 20% and in 17 from 3:00am to 8:00am next day only 2%. What can make that to happen?
