Version control
|
|
===============
|
|
|
|
Nextcloud supports simple version control system for files. Versioning creates
|
|
backups of files which are accessible via the Versions tab on the Details
|
|
sidebar. This tab contains the history of the file where you can roll back a
|
|
file to any previous version. Changes made at intervals greater than two minutes
|
|
are saved in **data/[user]/files_versions**.
|
|
|
|
.. figure:: ../images/files_versioning.png
|
|
|
|
To restore a specific version of a file, click the circular arrow to the right.
|
|
Click on the timestamp to download it.
|
|
|
|
The versioning app expires old versions automatically to make sure that
|
|
the user doesn't run out of space. This pattern is used to delete
|
|
old versions:
|
|
|
|
* For the first second we keep one version
|
|
* For the first 10 seconds Nextcloud keeps one version every 2 seconds
|
|
* For the first minute Nextcloud keeps one version every 10 seconds
|
|
* For the first hour Nextcloud keeps one version every minute
|
|
* For the first 24 hours Nextcloud keeps one version every hour
|
|
* For the first 30 days Nextcloud keeps one version every day
|
|
* After the first 30 days Nextcloud keeps one version every week
|
|
|
|
The versions are adjusted along this pattern every time a new version gets
|
|
created.
|
|
|
|
The version app never uses more than 50% of the user's currently available free
|
|
space. If the stored versions exceed this limit, Nextcloud deletes the oldest
|
|
versions until it meets the disk space limit again.
|
|
|
|
|
|
Naming a version
|
|
----------------
|
|
|
|
You can give a name to a version.
|
|
|
|
.. figure:: ../images/files_versions_actions.png
|
|
.. figure:: ../images/files_versions_naming.png
|
|
|
|
When a version has a name, it will be excluded from the automatic expiration process.
|
|
|
|
Deleting a version
|
|
------------------
|
|
|
|
You can also manually delete a version without waiting for the automatic expiration process. |
