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 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 have filled up with archives. Free up disk space on destination by deleting unnecessary archives as described in Acronis True Image 2019: 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.
5. Lastly, set up automatic cleanup rules to avoid filling the storage completely: see Automatic Cleanup Rules section in product documentation.
