Backup error. Write operation failed. The specified network name is no longer available.
We have been sucessfully running a ReadyNAS Pro Business Edition (Radiator 4.2.27) for one level of network backups each day. Normally the NAS has been powered-on all the time. A scheduled backup jo...
What command do you use in your script to shut down the NAS?
If you add a test in your script after WoL but before starting the backup to test the availability of the share, like trying to access the share in a while loop exiting when successful, does the share eventually become available? How long does it take?
Do you see anything specific in dmesg after WoL, when your script fails to write to the share?
Thank you for your suggestions.
We are using Plink.exe NAS_IP -l username -pw "password" -ssh -P 22 - 2 -m "C:\shutdown.txt" in a batch file .
The text file "shutdown.txt" simply contains the instruction shutdown -h now
We have been successful so far with pre-conditioning the main backup with a small backup ~ 1Gb (ignoring whether this is successful or not).
Once we get our backup regime more on track we will go back and investigate dmesg for differences.
It would be possible to adjust the script to wait until a successful write reponse fron the NAS but we would need to be able to manage the situation where we fail to get a response from the NAS and how that erro is handled.
'The specified network name is no longer available' does show up in the Windows event log so we are not ruling out something on the SBS2003 server side which needs to be refreshed or stopped / restarted to re-establish a good / fresh connection to the NAS when it reappears on the network.

To gracefully shutdown the NAS, you should use rnutil rn_shutdown or rn_shutdown directly (use -r for a reboot).
