Upgrading Veeam Availability Suite

This is probably this simplest thing ever, but I figured I’d throw it up here in case someone thinks it is harder than it is.

1.) Download the update ISO from the Veeam Website and get that mounted on the box that has Veeam installed.

2.) Run the Setup executable and select Update on Backup & Replication

3.) Select Next, check whether to update remote components or not, select Next again, and finally select Finish.

That’s it!  It really is just that simple.  Follow the same process for Veeam One.

Veeam Error: Agent failed to process method {DataTransfer.SyncDisk}

The other night I had my Veeam box decide it was not going to backup my VM’s.  This, naturally, is unacceptable behavior!  The error I was getting was the following (I cut out all the junk from my environment):

Processing <VMName> Error: An unexpected network error occurred. Failed to write data to the file <StorageUNC>.vbk]. Failed to download disk. Shared memory connection was closed. Failed to upload disk. Agent failed to process method {DataTransfer.SyncDisk}.

Before you jump to the obvious, there were no network related issues.  I did some digging and I found the solution!  I apologize to the random blog that I found the solution from, I have since closed the tab and lost the link.  Anywho, the following directory needs to be empty:


I had a log file left in the directory.  Cleared it out, bounced the box (because why not?), and kicked off a backup of all my VM’s which completed without issue.
