The versioning app expires old file versions automatically to ensure that users don’t exceed their storage quotas. This is the default pattern used to delete old versions:
-
For the first second we keep one version
-
For the first 10 seconds ownCloud keeps one version every 2 seconds
-
For the first minute ownCloud keeps one version every 10 seconds
-
For the first hour ownCloud keeps one version every minute
-
For the first 24 hours ownCloud keeps one version every hour
-
For the first 30 days ownCloud keeps one version every day
-
After the first 30 days ownCloud keeps one version every week
The versions are adjusted along this pattern every time a new version is created.
The Versions app never uses more that 50% of the user’s storage quota. If the stored versions exceed this limit, allAccess deletes the oldest file versions until it meets the disk space limit again.
