We have a windows Server 2003 (SBS) on which, the windows Backup Utility is creating a System State backup.  This system state backup is now huge (Just reached 300GB).

I have tried doing a manual backup to another filename to see if it was something to do with retention.. but the new one was looking to be a similar size.  Im not too sure what is making the file so big.  I had a look around google for some information but i cant find much about how i might shrink this.

This is a small company with 14 users.  The server is running exchange, Active Directory and DHCP and is the only server in the office.

Hi guys,

Thanks for the replies..

The only item in the backup was  "System State".  None of the drives or any other files / folders etc were selected.  I have since found that it was appending the new backup to the old file so i was wrong about retention.

It is still approx 7GB though.  Is this too large or is this about average?

When the ntbackup starts it estimates 2990 files to be backed up.  The first file processed takes a while to back up and is over 6.5GB is this something we can shrink down somehow?

sounds about right for a server with AD, Exch and DHCP/DNS - my std 2003 member servers are roughly 480 - 690MB for their System State only backups.  My only 2003 DC just has AD and DNS running, and is currently running @ 698MB.

ntds.dit is 25MB  
sysvol is 11.1MB

It seems that although the Windows Backup software states that the backup media will be overwritten it is still "Appending" the data when it runs the automated backup.  I thnk i will need to use the batch file method as mentioned by sabk and the further information from jakirkhan.

you can choose a different name when running the backup, usually with the date in it, so it creates a fresh file each time, rather than appending all the time.

I was unable to use the method where the different names would be created as these are to be backed up remotely over night.  I have set a batch file to remove the old version of the file and create a new one once a week.  the remote backup software then uploads this new version to the backup server.

I would like to thank everyone for their help and information.
