This post is the third part of the “Vizioncore vRanger Quiescing & VSS Setting for image backup of Virtual Machines.” to start from the beginning of the series please start at: Vizioncore VRanger (Previously ESXRanger) Quiescing & VSS Recommended Settings Vizioncore vRanger (Previously ESXRanger) Quiescing & VSS Setting for non-database Virtual Machines.
As mentioned earlier, Quiescing is recommended to be disabled for virtual machines running a database application to avoid problems which seems to often occur when quiescing virtual machines that run a database application. In addition, for database servers which support VSS (MS SQL Server, MS Exchange, Active directory, and so on) it’s recommended to enable VSS to obtain a transactionally consistent backup image. As that backup can go over SAN using VCB, or over LAN using vRanger directly below is the required changes for both cases:
Ensure that Quiescing for vRanger backup is disabled (“disabled by default”). In addition, if your database applications support VSS you should Install VSS for that virtual machine & enable VSS by placing a check mark next to “Enable VSS” in vRanger. Setting is illustrated in the images below:
(How to install VSS in Database Virtual Machines)
(Disable Quescing & enable VSS)
As the “disable Guest Quescing” check mark does not affect VCB setting, and Quescing will always happen when running VCB if the VMware “Filesystem Sync Driver” which installed as a part of the VMware tools is installed on the VM to backup. For database servers where you are using VCB to backup and want to disable Quescing you will have to remove the Filesystem Sync Driver from under control panel => VMware tools on the virtual machine to backup as shown in the images below:
After that if your database support VSS, you will need to install VSS on the virtual machine you want to backup as well enable VSS for the machine you want to backup from vRanger as below:
