Retention of files
|
|
==================
|
|
|
|
Nextcloud's Files Retention app allows to automatically delete files that
|
|
are tagged with a collaborative tag and have a certain age.
|
|
|
|
Example
|
|
-------
|
|
|
|
After installing the Retention app as described in :doc:`../apps_management`
|
|
navigate to the configuration and locate the Workflow settings.

|
|
:alt: Sample rule to delete files after 14 days.
|
|
|
|
The rule from the example will delete all files tagged with ``Temporary file`` after 14 days.
|
|
|
|
While creating a rule you can use the "Notify users a day before retention will delete a file" option to
|
|
make sure the the users will get a notification before a file gets deleted.
|
|
|
|
Common misconfigurations
|
|
------------------------
|
|
|
|
Public collaborative tag
|
|
^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Similar to :doc:`access_control` retention should use ``restricted`` or ``invisible``
|
|
tags. Otherwise any user can remove the tag and the file is not removed after the given
|
|
period. Use :doc:`automated_tagging` to assign such tags to newly uploaded files.
|
|
|
|
File age
|
|
^^^^^^^^
|
|
|
|
Currently retention is based on the creation date of the file. The sync client sends
|
|
the **original** creation date to the server, while uploading through the web interface
|
|
will create a new file with a **new** creation date.
|
|
We hope to be able to add a ``upload date`` to the filesystem soon, which would make more
|
|
sense. Until then this potentially unexpected behavior has to be taken into account.
