My server is Windows 2008 r2, and I have taken backups of all volumes using Windows Server Backup every day.
Last week, all previous older backups has been deleted due to making free space in the backup volume, and then only the latest backup has been created, and I found the following Event ID at the same backup time.
However, until I encountered this problem, all older backups hadn’t be deleted and only the oldest backup had been deleted in the past times even though I got same Event ID.
-----------------------------------------------------------------------------------------------------------------------------------------------
The Shadow Copies of volume X: were deleted because the shadow copy storage could not grow in time.
Consider reducing the IO load on the system or choose a shadow copy storage volume that is not being shadow copied.
Log Name: System
Source: volsnap
Event ID: 25
Level: Error
-----------------------------------------------------------------------------------------------------------------------------------------------
I’m using the dedicated backup volume, so I cannot understand why the cause of this problem is due to high I/O load.
Also, even if I got the Event ID, why didn’t all older backups be deleted every time?
I’d like to know the appropriate reason, because I’d like to keep older backups with the latest backup in the backup volume.
Then, Should I execute Diskshadow command to delete the oldest shadow copy to make free space in the backup volume by myself to prevent same problem?
Could you please give advice about this problem?
Thank you.
