It backs up the C: drive fine, moves to the D: drive and it just seems to time out and fail.
So I consult the report -
Event Type: Error
Event Source: NTBackup
Event Category: None
Event ID: 8001
End Backup of 'D:' 'Warnings or errors were encountered.'
Consult the backup report for more details.
There is space, the drives are online and accessible. Any Ideas?
Backup started on 08/03/2013 at 21:42.
Error: The device reported an error on a request to write data to media.
Error reported: Unknown error.
There may be a hardware or media problem.
Please check the system event log for relevant failures.
The operation was ended.
Backup completed on 09/03/2013 at 21:51.
Time: 1 day, 0 hours, 9 minutes, and 42 seconds
Error: D: is not a valid drive, or you do not have access.
The operation did not successfully complete.

On my servers this is normally a sign of problems on the media, what are you backing up onto??

NAS - Seems like no errors on the device.

- Rep Power
We had this some time ago and to be honest it turned out to be lack of space. Not sure if ntbackup creates large temp files or similar, but as I say at first glance there appeared to be sufficient space - but there wasn't!

I had a similar thing backing up to a USB caddy. I could access the backup drive, manipulate files and all looked fine. But NTBackup failed. I swapped out the caddy and it's right as rain. Do you have another backup device you can try?

2TB drive with a backup size of approx 900GB, 1.7Tb Free
Just did a new backup selection, will see how it goes.

Failed with the same error.

How big is the backup file getting? Could it be running into a maximum file size problem on the filesystem of the NAS?
Conversely, are there any large files in the source that could be too big for NTBackup?

Have you tried backing up a smaller number of files? That should help determine if it's a file size issue.

@AngryTechnician @laserblazer - just trying your suggestions now, will let you know.

Is the drive mapped ? Or are you backing up using \\blahblahserver\share ?

Seems specific to the D: drive, will investigate further.
