61992: Acronis Cyber Protect Home Office, Acronis True Image: Backup fails with "There is not enough space on the destination drive to perform a backup"

Last update: 12-10-2022


Backup task fails with the following error:

There is not enough space on the destination drive to perform a backup


The software detected that there is not enough space on the destination to complete the backup.

  1. If this is the first time you create a backup, make sure that the selected destination has enough space for the data that you want to backup. Specify a different backup destination or select less data for backup.
  2. If you have previously created backups with this backup task, most likely the destination has filled up with archives. Free up disk space on destination by deleting unnecessary archives as described in Acronis True Image: How to delete old backups.
  3. If there are old .TIB files in the destination location that do not correspond to any of backups in Acronis True Image interface, turn off Active Protection temporarily and delete those .TIB files in Windows Explorer to make room for new backups.
  4. If you do not know what consumes disk space in the destination location, use a free disk space analyzer tool: DiskSavvy, WinDirStat or any other.
  5. If previously you deleted .tib/.tibx files via Windows Explorer (not via Acronis True Image interface), then the backup database may contain incorrect information about free space on the destination. Refresh the data in database: delete the backup task (move the mouse over the backup in Acronis True Image, click a small down arrow button next to the backup name and select "Delete", then click Remove in the pop-up window) , and after that add the backup again as described in Adding a previously created backup to the backups list
  6. This error may occur if there is not enough free disk space on the source disk for Microsoft VSS snapshot. If less than 10% of the source disk is free, we recommend freeing some space on the source disk for proper snapshot creation. 

    If there is enough free space on the source disk, run the free Acronis tool for troubleshooting Microsoft VSS issues: Acronis VSS Doctor to exclude possible issues with VSS.

After resolving the issue, set up automatic cleanup rules to avoid filling the storage completely: see Automatic Cleanup Rules section in product documentation.
