BA 9.2.2 incorrectly detects RDX

by Navion » Sat Mar 05, 2016 3:11 am

We're getting failures with 9.2.2 because the Basic Backup indicates that it wants to backup to drive Z: (Retrieving volume information...This would backup volume Local Disk(C:) to Z:...There is not enough....)
When I set up the backup, I indicated that the RDX was Drive L:, and I've verified that as far as Windows Server is concerned, it still IS drive L:. I ran Detect and didn't get any errors.
We don't have a Drive Z unless BA is creating a virtual drive for that.
Also, I don't seem to be able to select the files I want. BA seems determined to take the whole C: drive (which is less than 500 Gb ) when I only want to backup about 3 directories.
Finally (Sorry this is so long) is there a way to only use 2 RDX disks for the backup (odd day/even day) instead of using 5 (one for each day of the week)?
This is a very small office, not using exchange or any databases...just essentially file storage.

Hi there,

It's Stuart here from the BackupAssist team, thanks for posting on our forum.

In regards to the Z: drive, can you verify for me if you're running your backup to a Data Container? More information on this is located at
If you are using a data container, then this will be mounted as Z: drive by default.

With the System Protection engine, if you've selected that you're wanting a bare metal capable backup - then BackupAssist is going to select the critical volumes required which is why your entire C: drive will be being backed up and not allowing you to select specific files/directories.

As far as using just two cartridges, you're able to do so. All you need to do is configure a daily rotating scheme and select 'Number of disks in your backup pool' (on the destination tab) as 2 and the software will automatically configure that scheme for two cartridges for you.

By the sounds of it, I actually think you'd be best served by running a File Protection backup to the RDX drive. This is a file level backup which will allow you to easily select the files/folders which you're wanting backed up. More information on this engine is found at

Thanks, Stuart, that did the trick. Looks like I was trying to have my cake and eat it too (too many options). Everything's working perfectly now. Thanks very much!
