VSS error after Windows 10 1903 update

Thread needs solution

Hello,

our customer is running Acronis 12.5 build 14330 on a HyperV machine.

Backups of several VMs work without problems.

3 Windows 10 VMs were recently updated to build 1903.

Since then Acronis backup is failing on these 3 VMs:

----------

Es wird ein crash-konsistenter Snapshot der virtuellen Maschine '76C85EDC-4DF4-4F99-8C3C-B4FA61DB921B' erstellt, weil kein applikationskonsistenter Snapshot von ihr erstellt werden konnte.
Der Task wurde mit Fehlern abgeschlossen.

----------
Fehlercode: 139
Modul: 83
Zeileninfo: 0x6D1FE7F1E47BA15F
Felder: {"TaskDescription":"Prüfpunkt des virtuellen Computers wird erstellt","$module":"hv_srv_vsa64_14330","ErrorCode":"32768","ErrorDescription":"Fehler beim Prüfpunktvorgang für \"RZ-03\". (ID des virtuellen Computers: 76C85EDC-4DF4-4F99-8C3C-B4FA61DB921B)"}
Nachricht: Der Task wurde mit Fehlern abgeschlossen.

I ran Acronis VSS Doctor on these VMs and it says: 

"insufficient free space" on the Windows Recovery partition (82 of 507 MB free, minimum 320 MB)

 

I think the Windows build update rearranged the Recovery partition somehow.

 

What can I do so that these VMs can be backup again?

 

Regards

Dennis

Hello Dennis,

thanks for posting on Acronis forums!

Looks like you need somehow to cleanup the recovery partitions.

Could you please share a full log of the failed backup operation? Please follow Overview ->Activities, select this log, download and share it here.

Hello Dennis.

According to the lof file data, the VSS backup failed but crash-consistent backup has been created. Which means that VSS has not been used during backup due to problems with the recovery partition:

2019-09-17T22:17:40:082 02:00 10088 I00490000: Der crash-konsistente Snapshot 'AcronisBackup' wird erstellt...

Thus, your client has a non-VSS backup of his Hyper-V VM. However, if there were any application that requires application-aware backup (e.g. SQL. Exchange, AD), then these databases would not be recovered separately only with a full machine backup. 

 

Hello Maria,

I understand.

We would like to do an application-aware backup again, like it worked with the previous VM versions.

How can I cleanup these recovery partitions?

Regards

Dennis
