Controlling File Versions and Aging
Most Nextcloud users want to be able to retrieve old version of their files while ensuring they don't exceed their storage quotas. The Versions app (files_version) automatically delete old versions according to this pattern:
| For the... | Nextcloud keeps... |
| first second | one version |
| first 10 seconds | one version every 2 seconds |
| first minute | one version every 10 seconds |
| first hour | one version every minute |
| first 24 hours | one version every hour |
| first 30 days | one version every day |
| After the first 30 days | 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 currently available free space. If the stored versions exceed this limit, Nextcloud deletes the oldest file versions until it meets the disk space limit again.
You may alter the default pattern in config.php. The default setting is auto, which sets the default pattern:
’versions_retention_obligation’ => ’auto’,
