[FR]: Clean up remote backups

[tbelway]

Is your feature request related to a problem? Please describe.

The ability for rclone to delete on the remote is already baked in. However, the regex used to validate the config prevents deleting on the remote, citing a source is required.

Describe the solution you'd like

Remove the source requirement on delete command.

My apologies, it does seem to delete old files from the remote. It is too early for me :)

Ignore:
I was also thinking that rclone was able to keep two folders in sync. I prefer to delete my hourly backups automatically, also on the remote. Am I overseeing some option?

My config

- name: Sync Backups to idrivee2
  schedule: 15 * * * *
  command: sync
  sources:
    - /backup
  destination: idrivee2:bucket
  include:
    - AutoBackup*
  exclude: []
  flags: {}
