In R75 when you create a backup job using the SCP method you may find that it fails to logon to the SCP server. If you check the logs it will show that the username/password failed.
This is because when you schedule the backup job in the web GUI it saves the password incorrectly in /var/CPbackup/conf/backup_sched.conf.
To fix this you must use the CLI to schedule the job. This saves the password correctly.
1. SSH from an allowed host to the management server
2. Schedule the backup:
backup -l --sched on 07:00 -w 1 --scp <server IP> <username> <password>
3. Check that it worked OK in the GUI.
