"can't back up" issues with a 2008 R2 backup

[Alfaj0r]

Using version 7.6.123 on a multi-server install.

 

I'm backing up an entire Windows 2008 R2 server, and I'm getting error messages every single time the job runs:

• 
  -Can't back up registry, error -517 (backup client is busy)
  -Can't back up WMI Repository, error -517 (backup client is busy)
  -Can't back up COM+ Class Registration database, error -517 (backup client is busy)
  -Can't back up Removable Storage Manager, error -517 (backup client is busy)
  

Each one of these is an email sent to 4 people, so it's pretty annoying to have to delete these every single time the backup runs (which is 4 times a week!).

 

Now, according to a post by Mayoff in another thread , the one about the Removable Storage Manager is a "cosmetic error".

Can I make it so the backup excludes trying to back it up, so that I don't have to have 4 people deleting an email 4 times a week?

 

On that note, what are the chances that the other issues are also cosmetic?

I'd appreciate any help in figuring out how to keep the errors from happening. The rest of the backup seems to run fine, but the errors are annoying and make the IT management feel a bit uneasy.

I got the same problem with some (but not all) of our Win 7 clients.

 

I think you need to upgrade to 7.7 to be able to backup properly.

Upgrade, you say?

Is that different than an update? Because I checked for updates, and there are none available.

Normally, updates are free but upgrades cost money. (That's not only for Retrospect.)
