How to clean Miab and free some space

[Feydreva]

Manual Backup Frequency for MIAB?

Pull via rsync from your backup server daily at approximately 4-5 AM. MiaB makes a full backup and retains it usually for 28 days adding an incremental backup daily during the daily maintenance period. You need all of this data for a successful backup restoration. Don’t forget to store the secret_key.txt file somewhere safely.

If I look at my duplicity collection status, chain starts 2024-11-17
that s more than 28 days…
102 backups sets, and 109 volumes

any idea on how to clean this ?
