I ran out of disk space on my server, which mainly hosts a nextcloud instance. Surprisingly I found tons of files I deleted ages ago in
It turned out my config.php was missing an entry for
trashbin_retention_obligation, which as a consequence defauls to
auto. I’ve now added the following line to configure a minimum and maximum amount of days that deleted files are kept:
'trashbin_retention_obligation' => '1, 7',
BTW: I think the default behaviour at least raises a data privacy issue.
