Backup a VMware running VM
I have always wanted to be able to backup a running virtual machine. That way I could make regular backups of the files that make the VM without actually shutting down. Warning--by using this method the VM believes it was shut down improperly.
Delete all virtual machine snapshots.
Take a new snapshot of the virtual machine. Title this snapshot "Temp-Backup" (the name is not important, just label something to delete.) You do not need to capture memory, but queisce the file system if possible.
Browse the datastore that hosts the virtual machine and open the folder where the machine resides.
Download a copy of the VMDK virtual disk file. Do not download the snapshot file (this file is in use and cannot be accessed).
Remove the snapshot on the virtual machine.
Download the rest of the files that make up the virtual machine. (.nvram, .vmx, .vmsd, .vmxf, etc).
Several projects are scripting to do this manual process. If you want to automate the process look into the script.
