SQL Backup Issue

Posted on 2009-07-01
Last Modified: 2012-06-27
I have a backup job that runs everynight through SQL server 2005 to a NAS device.  The job fails every other night.  When it fails I get the error that says the network name cannot be found.  Also I can run the job manually at any time and it runs just fine.

Thank you,

are you hitting the NAS by UNC or by mapped drive?

Anything in the event viewer around the time the job is failing?

I am going to the NAS by UNC.  In my event viewer I have this error message:
18210 :
BackupMedium::ReportIoError: write failure on backup device '\\\Share\SQL Backups\Critical\BAANDB2.bak'. Operating system error 64(The specified network name is no longer available.).

error message proves my doubts, your network loosing the connection with your NAS I guess.

could be the device failing itself.  Any jobs to power cycle the device or anything?

Power Cycling the NAS after each backup has resolved the issue. Thanks!
