I cannot find the password for the restic incremental backups using SFTP.
It is not here: /home/domain.com/domain.com
Could not find it in any Cyberpanel database table.
No emails sent.
However, the backups are created and I am able to restore them in Cyberpanel, "Incremental Backup - Backups v2 - Create/Restore V2 Backup - Restore backups.

This log file “/home/cyberpanel/incbackuplogs” contains this line, multiple times:
Starting Incremental Backup job..

Any clues?
