Hello,

my mail-in-a-box is growing.
How to clean ?

4.0K    /home/user-data/mailinabox.version

Looks like most of the space is taken by backups.
I checked the /home/user-data/owncloud-backup folder last backup was 2024-10-29
Not sure when theses are created . Any idea ?

I would also like to clean the backup in /home/user-data/backup/encrypted
But I am notr sure on how to do that wityh duplicity in place. where to start ?

Thank you for your help

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 ?

No advice on the duplicity backups.
The owncloud-backups are created on an update of Nextcloud. If it is running ok, you can delete those.
To clean up /var/log/journal use sudo journalctl --vacuum-time=10days

There might be more advice, search in the forum, there have been topics on this before.

Would it be easier to just delete (back up before deleting) the current ones and start from scratch if you want to use Duplicity to back up your MIAB as I suspect something did not go to plan between version upgrades maybe … ?
