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.

Sample

Sample rule to delete files after 14 days.

The rule from the sample will delete all files tagged with Temporary file after 14 days.

Common misconfigurations

Public collaborative tag

Similar to Files 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 Automated Tagging of Files 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 behaviour has to be taken into account.
