Windows Server Backup Error – low disk space error (error code 2155348010)

Windows Server Backup (WSB) was introduced with Server 2008, replacing the functionality of NTBackup in earlier versions of windows.  WSB uses automatic space and version management, so in theory there should be no need to manually clear old backups to make space for the new ones.  Of course the difference between theory and practice is that in theory there is no difference; in practice there is…






You may one day notice that your WSB backups fail with error code 2155348010 (hex 0x8078002A) “One of the backup files could not be created”.  If you check the backup target disk you find there is little free space.  You can format the disk (losing all backups on it), buy a larger disk, or try deleting snapshots from the disk using Diskshadow.exe.

We will see in the below demostration How we can delete the Windows Server Backup Copies and these are the exact steps which you can follow… Lets Explore

Error: Snapshots were found, but they were outside of your allowed context. Try removing them with the backup application which created them.

Open command prompt
