What happens if my NAS is not reachable when the backup starts?

Q: What happens if my NAS is not reachable when the backup starts? 

A: BmuS has a built-in retry mechanism. It will try to ping your NAS (configured via NAS_IP) multiple times. If it fails, it waits for a few seconds and tries again. You can configure the number of retries (PING_RETRIES) in bmus.conf. If it still fails, the script will abort to prevent errors, unless you have set IGNORE_FAILED_PING=1.
