The error log is full of these errors as well. Not the best solution but it is a lot more reliable than the QNAP device at the moment. Does this error mean that disk 3 is now dead? Even though it is showing as ok in Disk Management? Currently the Backup to Disk I am using is a MAxtor 1tb USB.
"In degraded mode Read only, Failed Drive(s): 3". Raid Management still says the array is degraded. The disk was replaced and the rebuild failed, even though all lights are green. Disk 2 died and now the array is not usable. It was working well until I had a disk failure. I created an iSCSI target of 1.5tb and attached it to the backup server.
The disk array on the NAS is 3 x 1.5tb in Raid 5. The system we run BackupExec 2010 on is Windows Server 2008 64Bit. I imagine because of the volume of data that is thrown at the NAS. Image dumps tend to fail more consistently. In fact nightly incremental jobs are much less problematic. Sometimes you can retry the job and it goes through without a hitch.

So i think the error message you have from the tool is not related to the error you have when running the backups.
However, when you send the backup to the NAS, the backup are saved in a big v2i file, and not in many files. We will check the behavior with the number of open files. The test could only open 9992 of 10000 files." "Check the configuration to see if there is a way to increase the number of open file handles." Is there a way to increase the number of open file handles? Alan Dear Alan, Thank you for the feed back. "The appliance is unable to maintain a large quantity of open file handles. Symantecs tool to test the connection to the NAS gives an error on completion. The backups are intermittently failing with "unable to read/write to/from disk errors or the network disconnects.
