Backup stuck in loop

I’ve setup remote backup to a remote FTP server and it seems to be stuck in a loop.

Looking at the proccesses running I see

asterisk 20648 0.0 0.0 11296 1300 ? S 08:52 0:00 sh -c /var/lib/asterisk/bin/backup.php --id=3 2>&1
asterisk 20649 0.5 0.6 182504 26312 ? S 08:52 0:00 php /var/lib/asterisk/bin/backup.php --id=3

but if I use a kill -9 on those process they just restart and my ftp server just fills up with new files, I’m also unable to access the web GUI until I reboot the server.

has anyone seen this before?

Did you import old backup profiles with restore? Delete all the backup jobs and reenter them.
