Veeam Error “There is not enough space on the disk.”

Share This Post

The generic “There is not enough space on the disk” error message is a fairly common and easy issue to investigate and resolve. The error is caused by the backup repository destination storage running out of space for the backup to run. The storage where the backups run differs from standalone agents and backups through your Veeam Backup & Replication console.

If you are seeing the error message for a Standalone Veeam Agent backup:

  • Please check your job settings to verify where the backup data is being sent. On occasions, the wrong location has been selected, causing the wrong storage to fill up.

  • After verifying the correct storage is selected, navigate to File Explorer to verify that the storage is visible. If it is not visible, this may indicate an issue with the connection between the storage and the machine being backed up.

  • If the storage is present, verify if there is enough space for the backups to run. If your storage has filled it, it may be necessary to clean up data. This may involve removing old unneeded data or lowering the retention rate. Once there has been enough free space cleaned up, you may kick off a backup.

If you are seeing the error message for a VM or Machine on Veeam Backup & Replication Console:

  • You can backup both VMs and physical machines through Veeam Backup and Replication. Please check your job settings to verify where the backup data is being sent. On occasions, the wrong location has been selected, causing the wrong storage to fill up.

  • After verifying the correct storage is selected, you can verify that the storage is accessible by rescanning the repository. In your Veeam Backup & Replication console, navigate to the Backup Infrastructure tab, the select Backup Repositories to populate the list of your backup storage. Veeam will show you storage information here, but right clicking and rescanning the repository will verify if the connection. If the rescan fails, this may indicate connectivity issues between Veeam and the storage.

  • If your storage is accessible, but has filled up, it may be necessary to clean up data. This may involve removing old backup chains, unneeded data, or lowering the retention rate. Once you have freed up space, retry your backups.

There may be additional reasons that may be preventing your backups from running. Please reach out to Support@Managecast.com to help troubleshoot and get your backups running successfully.
