Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I am doing system state backups on a Windows Server 2008 R2 Enterprise (Service Pack 1) machine and expected the backups after the first one to be incremental. However with each backup a new directory with vhd files are created and the vhd files are almost the same size as the with the first backup. So the backups does not seem to be incremental.

I used the following command to do the backup:

wbadmin start systemstatebackup -backupTarget:f:

I played around with the settings under "Configure Performance Settings" in the Windows Server Backup plugin in Server Manager but according to the description at the top of the dialog these settings are not applied to system state backups.

Are there any settings available for wbadmin system state backup to make the backups incremental?

I think it's better for you to pick a professional backup tool with incremental backup.

I know that both easus todo backup and handy backup offer incremental backup.

but, I'm not sure whether handy backup can support system incremental backup or not.

maybe you can check it.

but I'm sure that easus todo backup can do system backup, clone disk/partition.

and it's price is quite fair.

Windows Server Backup uses Volume Shadow Copy Service and block-level backup technology to efficiently back up and recover the operating system, files and folders, and volumes. After the first full backup is created, Windows Server Backup automatically runs incremental backups by saving only the data that has changed since the last backup occurred. Unlike previous versions, you no longer have to worry about manually scheduling full and incremental backups.

Is the changed data supposed to be copied/replaced to/in the same VHD that was created by the first backup? I get a new directory with a name like "Backup 2011-03-15 104335" with every backup that contains a VHD file of roughly 7GB. –  user74513 Mar 15 '11 at 10:43
