Veeam backing up volumes without a drive letter assigned

Which backup method did you choose for the job?  There is entire computer and also volume level.  Maybe this will help - https://veeamcookbook.com/vbr/Backup/AgentBackup/AgentBackupWinServer.html

Hi ​@APK17 -

“I’m trying to use just a single backup job for all of the machines because I understand that dedup only works for backups done as part of the same job.  Am I wrong on that?”

> Nope..you are indeed correct, as stated in the Guide here.

“Is this a bug in Veeam that it will back up volumes without a drive letter assigned or intended behavior?” 

> Good question...never really thought about this before because 99% of the time this is the case. In looking at the VAW Guide on Volume Backup, it appears this is the case. I wonder if you can try and exclude folders (root folder of these) to see if that works.

Best.

I’m currently using a Volume level backup because that method allows for excluding a volume, E: in my case, and allows for BMR.

Before configuring the job to exclude E: I tried using the other “Backup the following volumes only” option.  I put C: and D: in the list, two of my computers have a D: drive, two do not.  This did work, meaning that it didn’t try to backup the drivepool drives, but Veeam would throw an error on the two computers that did not have a D: drive.  

Unless I’m mistaken you can’t exclude file/folders when you use volume based for your job, no?

Hi ​@APK17 -

Yes, that is correct. I think it may be best to switch to the file/folder backup option

The issue with that is you lose the ability to do bare metal restores.

Ah yes...as you stated earlier that’s also what you wanted. Hmm...I’m out of suggestions at this point.

Either way thank you for the discussion, I appreciate you taking the time to reply.  I’ve opened a support case with Veeam to see what they say.  

Anyone want me to update this thread with their determination?

Good deal. Yes..please give an update when you have one. Appreciate it.
