What is the threshold set for low disk space for this B2D ? And does this B2D have sufficient free space more than the threshold limit ?

Try pausing/unpausing as well. Have a look @ these KB articles too :-

Can you please post the B2D`s properties in a screenshot?

Are you backing up to a CIFS share, or an iSCSI LUN? If not iSCSI, and the NAS is capable of it, it's worth-your-while to check out this option as it's going to get around a number of issues (like authentication problems, connectivity, possibly disk utilisation etc).

Thanks!

Hello Tempera,

If this is the base version of Backup Exec 2010 with no revisions please upgrade to the latest Backup Exec 2010R3 sp3  See: http://www.symantec.com/business/support/index?page=content&id=TECH66724 

and also please check out the Backup Exec 2010|2010 R2|2010 R3 Hardware (HCL) to verify the NAS device is supported.

After upgrading, the Backupecex run (again) once ok; after that offline and low discspace.

Yes..and no.  I don't quite understand how to work this iSCSI thing. I have created an iSCSI LUN-1 and Target-1 with the NAS's wizard, but don't understand how to use them (how to set up visible.)120px_iSCSI.png

...unfortunately none of your screenshots are showing up correctly, but read my article below which will give you an idea on how to use iSCSI...

SOLUTION

I did test this (creating a local drive) on my Win7 and it was very simple indeed. Thanks for the advice. I'll let you know tomorrow whether it solved the problem.

Question: as I have now installed this new drive through one computer, is it possible to install it for the server too simultaneously (to be able to access it from two different computers)?

CraigV's picture

Yes, but just consider this very carefully. There is always the chance that data can be deleted from 1 server if someone logs on there for instance.

So just weigh up the possible implications with this.

Thanks!

Dear Craig,

The iSCSI setup seems to have solved the Low disk space -issue. Thank you for the assistance.

Just can't help wondering why Backup Exec doesn't work as normal backup to NAS? That is what it is sold for, isn't it? If one has to spend days and days to set it up, doesn't make a lot of sense.

...Windows plays no role in controlling disk access and storage on that NAS. So what I think happens is that the NAS might have more than enough disk space than Windows server can address, and it crops up with a message (error!) that the NAS is out of disk space.

iSCSI works like a charm. You can create up to 2TB LUNs, present to the media server, and group those into a far larger LUN for Windows to address.

Thanks!
