Yes, when you use the Windows filesystem compression the OS has to uncompress the data before it sends it to NetBackup. Filesystem compression does a wonderful job of slowing down your backups and beating on the disks.

Evening all

Wonder if I can seek some clarification. NBU 5.1+MP5+Win2k3 Server Master plus multiple SAN/Clients

I went to run a report "Client Backups" and wanted to see how many kb's were written during the backup. According to the Report, 3500984336kb backed up. This is approx 3,500GB or 3.41TB's  :-)

However, according to Windows itself, it claims that it shows 2.3TB of Data on the volumes. The volumes are compressed, so I wondered if NetBackup Report is showing uncompressed size?

Has anyone seen this?
Thanks
Simon
