- Using the /FU command and the above registry commands on a Windows 2003 Server with SP1? reportedly gives a throughput to a network drive (1gb backbone) at about 1GB per minute (load depending of course), with local disks being up to 1.6GB per minute.
Deleted line 28:
- Have the /FU and the above commands run and on Win2k3 with SP1? you should have a throughput to a network drive (1gb backbone) at about 1GB per minute. (load depending of course). It's between local disks it can be up to 1.6GB per minute. Between local disks for me was on a SAN though...

Describe BackupTimeAndSystemPerformance here.
to:
Backup Time and System Performance
When the Ntbackup.exe program uses buffered input/output (I/O) to write to a destination .bkf file, the cache manager and the memory manager in Microsoft Windows Server 2003 may handle a large volume of data at a high throughput rate. This process consumes valuable system resources and may affect system performance.Resolution
- Install either the hotfix mentioned here: http://support.microsoft.com/kb/839272 or SP1? for Windows 2003 to enable the use of the /FU command.
- Now, add the following script to the pre-backup script section in BackupAssist (Advanced Tab > Modify scripts to run before and after the backup > pre-backup script):
-

- There is a new command
- Perform Inventory before each backup
- Move tape to free media pool before each backup
This can be achieved by going to the Options tab of BackupAssist and then clicking on the link to access the Advanced Tape Drive Settings:
