To control number of synced file versions stored in Acronis Online Storage, you can set automatic cleanup options. In this case obsolete versions are deleted automatically according to the specified rules.
You can set the following cleanup rules:
Delete versions older than [defined period] - Select this option to limit the age of sync versions. All versions that are older than the specified period will be automatically deleted.
Store no more than [n] recent versions - Select this option to limit the maximum number of sync versions. When the number of versions exceeds the specified value, the oldest version will be automatically deleted.
The last version of a file can be deleted from the storage only manually and not as a result of automatic cleanup. Deleted versions cannot be restored.
