Urbackup Hyper-V Client 2.2.19 Does not backup Host drive SYSVOL, MBR and C:

1

Hi ,
Normally i can image backup SYSVOL , C and mbr without any problem. But since i start using the Hyper-V client, i suddenly can’t

I used the client (2.4.1.0) before with server version 2.4.1.2
and that backups the SYSVOL, C: and MBR straight away (worked)

Now i am using the version for Hyper-v because it are all Hyper-V hosts.
With the Hyper-v client (2.2.19) : (doesn’t work)
I run into trouble:

See the log:

Starting unscheduled full image backup of volume “C:”…
Request of image backup failed. Reason: Creating shadow copy failed. See client log file for details.
Transferred 206 bytes - Average speed: 7.008 KBit/s
Time taken for backing up client Machine: 4s
Backup failed

I have 3 hosts (server 2016) which contain Hyper-V machines, and all of them do backup the VM’s but not the C drive of the host machine itself.

The Backup host is using Windows Server 2016 server service 2.4.1.2.

debug log from random Windows Server 2016 client with Hyper-V client from Urbackup:

All the same 3 hosts seem to have the same issue.

I did not take great care to preserve the ability to backup the hyper-v host because I assumed that would not be needed…

Could you try if this version works better: http://beta.urbackup.org/tmp/UrBackup%20Client%202.2.19-hyperv.exe ?

Hi Uroni,

thanks for the super fast reply.

I will try it out !

I really would love this feature within the hyper-v client.
It will add a lot of options to my customers environment , which i remote backup.

I will let you know , if this version is working better.

And as i promised,

This installer works exactly the way it should be out of the box.
Great work.
You’re a artist. I love your work and contribution.

Thank you
