I have a two node Active\Active SQL Server 2005 Cluster. I am running three instances on each node. When I try to backup the DBs on the one instance on the second node... it fails with:
"BACKUP DATABASE [database1] TO DISK = N'\\sqlclust..." failed with the following
error: "The operating system returned the error '64(The specified network name is no longer available.)' while attempting 'FlushFileBuffers' on
Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters
not set correctly, or connection not established correctly.
I moved the instance to the first node in the cluster and it runs successfully. All other instances back up to the same Network share with no issues. If I try to backup the DBs on the instance that fails to the Network Share to the local drive... it is successful.
I have tried recreating the Maintenance Plan several times as well as removing the "Verify backup" option in the plan. I also have the memory set to Static amounts. I have increased the Instance memory, but it still fails.
Any advice would be greatly appreciated!
