How to delete server backups?

Found this and the thread indicates it takes a little while to update the database:

 

Use this command.

 

 

Wbadmin delete catalog

 

Deletes the backup catalog on the local computer. Use this subcommand only if the backup catalog on this computer is corrupted and you have no backups stored at another location that you can use to restore the catalog.

 

This subcommand applies only to Windows Server 2008. By running the command wbadmin delete catalog and clearing the event logs you will remove all previous information relating to out of date backups. when the next backup runs if there are already backups on that destination device (such as USB hard drive) the catalog will rebuild, it will also add more data into the catalog for every destination drive you run a backup onto if there were already backups existing. dont worry, ive done this loads of times, its not a problem.

 

(from Technet library)

 

As you can see this is not for everyday use and should only be used if the catalog is corrupt.

I was able to successfully perform this operation.

 

1)Run wbadmin delete catalog from a command prompt.

 

2)Run Event Viewer and clear log Applications and Services\Microsoft\Windows\Backup\Operational If you don't clear the Backup Operational log the backups will still be shown.

 

For some reason Dashboard reported Drive C needed to be checked for errors. Checked drive to clear message but there were no errors.

 

Dashboard now has a message that Server Backup needs to be Setup. Make sure your Server is functioning correctly because you will need to delete the backups on your Server Backup disk. I tried not deleting the backups and they didn't show up after the first backup and the backup ran way too quickly so I didn't trust the data stored on the hard drive.

 

Now the only Server Backup listed is the current backup.

Hi jmwills,

 

Purging the backup catalog was discussed earlier in the post #4 and served my purpose of configuring a new backup schedule on a different disk. However for those who rotate disks there don't seem to be a way to remove entries individualy from the backup catalog. I can delete the shadow copies using the diskshadow delete shadows ID {} command but the catalog still maintains the old backups. The only way right now seems to be to purge the entire catalog, run a new backup on the next disk which seems to import all the valid backups back into the catalog. Got to go to work now, but I'll try experimenting with a few things later.

thanks for the info. At least it looks like it IS do-able, even if it is pretty twisted.

I also just ran into this issue. I saw this shiny new WD Mybook 2TB on the shelf at best buy and couldn't resist. I removed my old 750 GB drive from the server and placed it in use in a different PC. Still all my old backup (that do not exist on the old drive anymore) still show up. Also, I think my backup DB is corrupted so I am going to take the advice above and do the following...

 

1)From the dashboard, removed the server backup schedule and removed the old hard drive from the backup pool

2)Remote desktop into the server and opened a command prompt

3)Type the command "wbadmin delete catalog"

4) Bingo! All server backup history purged from the catalog.

5) Install new HDD and configure server backups

6) Reformat old HDD

 

I'll post my results, but I have to say this, the Synology DS211+ is looking more and more attractive each day.

Ok, no matter what I did, I was not able to remove the Old Server backups from the catalog. Oh well I guess its not work worrying about but it would be nice if there was a built in wizard or something to manage your server backups.

 

Hopefully all the old ones just fall off after a while.

Hi,

 

Just want to say that this solution worked perfectly!

List of all backups cleaned up.

 

Thanks for sharing!
