Hi,

To "MCZ", what version of SQLserver were you running before the upgrade ?

and did you get any new issues after the upgrade ?

Previous version was 2012 Express Edition (so the basic setup which comes with installation of AD Connect) and now I see that I only installed SP1 for SQLServer 2016. In my case it worked and I didn't receive any other issues since then. Probably it is enough to repair the existing installation??

Hi all,

Not a Veeam user, but since this thread was what initially clued me in to the issue with the product we use for Hyper-V host-level backups of guests, I thought I'd chime in.

This definitely looks like a MS issue, but I haven't found any real acknowledgement of the problem anywhere from them. In hopes that we can raise the profile of the issue, I've posted to the AD Connect UserVoice as well as the MS Partner Support forums. Hopefully if you can add your voices to this, someone at MS will get involved:

The only solution that workt for us was to uninstall azure ad connect, install sql express (we used 2016 sp1) and reinstalled azure ad connect with option to use the manual installed express and a service account for sql (it's also working to use a sql on another server).

This works,

If you can accept that the AADconnect, is dead in the wather for a short period of time, a simple solution is this.

Use task scheduler:

1. Stop the AADconnect service shortly before the Veeambackup is set to run. (Powershell Stop-Service -DisplayName 'Microsoft Azure AD Sync')

---- The backup is running

2. Start the AADconnect again after a the backup has finished. (mine takes about 15min, so I start the service after 30min.) (Powershell Start-Service -DisplayName 'Microsoft Azure AD Sync')

Thats it.
My backup has been running 3 times this weekend without any further problems :-)

You should be able to start the service just after the snapshot has been taken (start it in the post-thaw script) because veeam releases vss-snapshot after vmware snapshot (if you are not indexing the filesystem).

ive been experiencing this issue - i found this - https://social.technet.microsoft.com/Fo ... errecovery

typically, i have to restart the server for it to complete a backup/rep. it usually requires a restart every few day as related to Azure AD Sync updating likely and causing issues with permissions. i changed the log on account of the SQL server VSS writer service to a domain service account with proper permissions to the DB. for now that seemed to solve it. i will give an update in a week or so to confirm whether or not the issue has resurfaced.

I have been following your post on the MS Partner Support forum and when looking at the SyncEngine-AutoUpgrader-XXXXXXXX-XXXXXX.log files in C:\ProgramData\AADConnect, I am seeing the auto-upgrade process being triggered every 6 hours as well starting on 10/23. However, what caught my eye is "Upgrading AADConnect to version: 1.1.648.0".

According to the version release history at https://docs.microsoft.com/en-us/azure/ ... on-history, this isn't a valid version number. Are you seeing the same thing?

Yep, I see the same version number in the logfile.

Changing the service account seems to be working for me. The first Veeam job after an Auto (non-)Upgrade completed without an error anyway. Thanks, Blake.

no problem, i still haven't had to restart this server and all jobs for it are still completing without any errors. at this point, i don't think it's just a coincidence and this may have fixed the issue on my end.

In my case, repairing the express-db-instance has resolved the issue...

Upgrading MSSQL Server 2012 Express LocalDB to SP4 fixed the issue for me. Multiple back up jobs finished successfully after that without restarting the vm.
