Well, I followed through, but when I execute the job, I get this error:
I did manually run rsync and it was successful:
Also, I'm not sure where the /home/remote-backup/bin/validate-backup-cmd.sh command is supposed to come into play?
How might I manually run the rsync command with the extra options to verify the command line? When I try that, it's prompting for a password, which would imply I don't have the keys set up right?
root@omv-pd:/var/lib/openmediavault/ssh/keys# rsync -avz -e ssh --numeric-ids -q -e '/usr/bin/ssh -oStrictHostKeyChecking=no -p 22 -i /var/lib/openmediavault/ssh/keys/openmediavault-1a5daba4-f676-4f33-a1b1-a7840deecf39' --delete-excluded --exclude=/lost+found --hard-links remote-backup@openfiler299:/mnt/vg-sda2/sda2-shares/MusicOnHold /media/4547cf41-3d1b-4133-af1f-c0fd9312fc53/OpenFilerBackups/
sure enough, if I manually enter the password, rsync transfers files successfully....though no output. I guess I'm not understanding how the key exchange is supposed to work.
