We had this before, now it’s back: the problem with not working scheduled backups after upgrading to a R70.xx version. Seen on R70.20, now I upgraded a environment from R70.10 to R70.30 – and the error is still there. The backup files are not correctly transfered to the SCP server configured.
The solution is to disable scheduled backup through the WebUI.
Then go to the /var/CPbackup/conf directory and delete the file backup_sched.conf.
Afterwards open the WebUI again and re-configure scheduled backup.
Next time the backup runs everything will be OK and files are transfered to another server with SCP.
