Wbadmin backup jobs fails at 30% cannot find the file specified

Hi all,

I'm having problem running a backup of my servers build in harddisk drive C: to an iscsi target

I use wbadmin to do the backup. Everything is going oké to up and around 30%

It the stops with the next message:

Running backup of volume Local Disk(C:), copied (30%).
Running backup of volume Local Disk(C:), copied (30%).
Running backup of volume Local Disk(C:), copied (30%).
Running backup of volume Local Disk(C:), copied (30%).

Backup stopped before completing.

the command start out okay

H:\>wbadmin start backup -backupTarget:h: -include:c: -allCritical -vssFull -quiet

Retrieving volume information...

This would backup volume Local Disk(C:) to h:.

Backup to H: is starting.

Where can I found out why the backup is failing?


the h: drive is an iscsi target which I can read and write to using the server.
So normally Windows sees the h: drive as a local drive.

If however I do the wbadmin to g: (usb drive) all works fine and backup goes 100%
So, I was thinking it has something to do with the iscsi target??

If I were you I would just test the same backup to local drive or network share.
It could be you iSCSI problem but if you do not test it with internal drive or standard network share you never know.

I have tested it with a usb drive and then all works correct.

That is Why I suspect the Iscsi target to be the issue here.
But why? I can read / write the iscsi target without any problem.

I'm now thinking of deleting the catalog to see if this has anything to do with the catalog being corrput?

My first thoughts were about the stability of your network connection. The fact that it starts writing and then fails point to this. Is this server using single NIC or more?

Launch an elevated command prompt. type the following at the commandline --

wbadmin delete catalog


.. this will clear the all the old backup data from the backup catalog.

Tried this it gets 4 times more

and then displays the same error.

The backup server has only 1 nic.
The sbs server has 2 nics

Why do I asked about NIC. Recently I met a problem where 2 NIC server was interrupting network writing operations. I found out that the API was trying to use both NICs at the same time but only one of them had NAS connected.
Try to disable one NIC and run backup. If it fails enable it and disable the other one. Try to backup.
