Description

BackupAssist has attempted to change the shadow storage limit on the source backup drives, but hasn't been able to.
The VSS snapshot manager within Windows requires some drive space to be able to store snapshots successfully so that the backup can be completed.

Resolution

Manually re-size the shadow storage on the source drives.

The shadow storage size can be checked and manually changed through a command prompt.

To check the current limit set: vssadmin list shadowstorage

To change the limit:vssadmin Resize ShadowStorage /For=X: /On=X: /Maxsize=XX%

This will resize the limit to XX percentage size for the X: drive.

We recommend setting the drive to 30%.
