Auto-delete older backups

[aj9669]

When backing up to my Nextcloud, whether it's over DAV or via Nextcloud, it accumulates all backups and causes my storage to fill up, until I have none left. Is there no possibility to automatically delete all old backups?

I use CalyxOS (always the newest stable version) on a Fairphone 4.

kind of a duplicate of #559

I suggest using the integrated WebDAV backend instead for now. Backups currently get duplicated only for fatal backup errors, will be fixed in an upcoming verison.

With #750 merged, we new only keep 3 daily snapshots and 2 weekly ones (one from this and one from last week). Anything older than this gets cleaned up automatically after each backup run.
