I’m thinking this might be better as a separate function from the regular “pruning”. For example there might be several auto-backups a day for updated plugins; these will add up fast, and I’d think we wouldn’t want them to crowd out scheduled backups. A couple of ideas:
1. A feature that manually deletes all auto-backups older than X (user-defined) days/weeks
2. Automatically prune auto backups older than X weeks – as a separate retention rule
Consider it a feature request perhaps? This came up a long time ago also, and others have asked for something similar. I was kinda hoping there was some progress on it already :)
I’m storing them off-site and have lots of space, but not unlimited – and deleting these auto-backups manually would be endlessly tedious…
