I have another customer that has two 250GB partitions added to their Domain Controller with no problems backing up. Now I'm having a hard time believing that an additional storage partition would cause this issue. So I then added a 500GB partition and tried the backup task. I then deleted the added partition from the Domain Controller and ran a backup task. The one with the added partition still did not backup. I separated each VM into it's own backup task and the two that didn't have the added partition backed up fine. When I set up Acronis VM-Backup to backup the three VMs, the backup failed. I then added a 1.4GB partition to the Domain Controller. I increased the RAID storage on my client's Host and restored 3 VM-Ware Virtual machines from an Acronis Backup Archive. I am working on the second one presently, and here is what I've found. Recently, the past year, I have ran into two of my clients that Acronis cannot backup. I have been using Acronis VM-Backup for years.
uninstall them, then reboot the VM, then install VMware Tools, making sure you select the VSS components (they are selected by default, but still worthy to double-check), then reboot the VM again to complete the installation -> next verify the presence of VMware Snapshot Provider under "vssadmin list providers" and if it's present then the quiesced snapshot should work without the error you referenced. Therefore I'd recommended going through VMware Tools re-installation procedure, i.e.
Some users discovered that removing this GUID key reference from Windows registry helps: see the following thread, however what actually happens is that removal of the key effectively disables VSS processing which is done through VMware Snapshot Provider in case of quiesced snapshot. This also explains why VSS works from inside the guest OS only, since in this case system state backup will use native Microsoft VSS provider instead of VMware Snapshot Provider used during quiesced snapshot. Writer Id: GUID corresponds VMware Snapshot Provider (see references to this GUID here). When running vssadmin list writers from an elevated CMD window I get the following: Reason: An error occurred while saving the snapshot: Failed to quiesce the virtual machine.
Message: Awaiting task 'CreateSnapshot' has failed. Message: VMware error: 'Remote method call failed.'. Message: Failed to open the virtual machine ( xxx/xxx.vmx). Message: Failed to perform the requested operation. I get the same error: Unable to Quiesce the VM.įailed to perform the requested operation. Take a snapshot of the VM with snapshot the VM's memory OFF and Quiesce guest file system ON. there are other errors in the event log but the error is always failing to Quiesce the VM.ġ.
I have a problem with Acronis for VMWare where I cannot create a backup of one of my hosts.
