Data size deffers after restoration.

Hi masters,

After making service completely down we took backup of internal storage
and restored on other mount point (from dmx storage)
But when we compare size there was 2GB data size deference.

We have done this restoration using netbackup.

Even after doing cp also we found same issue.

Appreciated for you early response

Chandra

Typically this means you had a sparse file and when you copy it, you fill in the gaps with zeros.

Compare what how? Bigger or smaller? What's

Re: Data size deffers after restoration.

What type of data are you trying to restore and/or copy? With NetBackup will tell you how much data it backed up. Does that match what you were trying to backup and did NetBackup restore everything?
