I got an backup issue on one of my VM. Here is the current situation:
Using Acronis backup to backup my VM
Server I want to get backup is
Windows 2003 Server Standard Edition Service Pack2
- Using vSphere client to manage my VMs
vSphere Client Version 5.1.0
When backup ran, it failed with error an message under "Create virtual machine snapshot" stage.
"An error occurred while quiescing the virtual machine. See the virtual machine's event log for details."
- Rebooted the server -> issue still exist
Install/Upgraded VMware tools
Installed and updated by using:
vSphere -> right click server -> Guest -> Install/Upgrade VMware Tools
But issue still exist
Uninstalled and re-installed VMware tools
Rebooted the box after the re-installation but still getting same error message.
Checked "vssadmin list writers" on the actual virtual machine
all VSS writers are:
State:  Stable
Last error: No error
Checked Event log (Event Viewer) on the actual virtual machine
In Application log, warning message found as following:
a) [ warning] [vmvss:vmvss] CVmSnapshotRequestor::WaitForOperation():2563: Async operation result: Operation aborted
Information message found as following:
a) The Volume Shadow Copy service was successfully sent a start control.
b) The Volume Shadow Copy service entered the running state.
Confirmed I can create snapshot without "Quiesce guest file system" option, but Acronis backup need this option to be on.
Due to Creating snapshot fails with "Quiesce guest file system" option on in vSphere, I believe that backup is failing at VM level and not at Acronis level
Thank you for reading this and any help or advise will be greatly appreciated.
