Feature Request: Cleanup of automatic backups

[scoopex]

OpenWB allows it to create automatic backups to a Nextcloud.
Due to the fact that this backup is created every night, hundreds of backup files are stored to the Nextcloud share.

It would be a good thing to have a configurable limit of backup generations to keep which has the effect that i.e. only the most recent 90 backup are kept (Pattern match the backups in the target folder, order them by filename, delete all except the last 90 files).
