Backup-data does not delete old backup

Support
1

Hello everyone.
I have a small problem, I explain:
I have configured a backup for my server. In it I have a 1Tb USB disk configured as a backup disk.
Duplicity backup, with a copy every day, retention of 7 days and full copy on Sunday.

After setting up the backup twice, I’ve run into the same problem: It doesn’t delete the old backup.
I leave you the log

Thanks for your help

Duplicity can’t delete the last full backup because the newer incremental backups depend on it.
It will be deleted when the Saturday incremental backup is 7 days old.

You could set backup retention to 1 day so it should remove the last full backup.

To remove old backups, you may also use command line:
