If I backup a virtual disk with standard backup software, will it be possible to use this disk in another VM, without...
any problems? How?
Also, how do I backup/copy an entire VM without any risks?
Are there any auxiliary files that we must delete before a standard backup?
- It will tell the virtual machine to dump cache so that all of the disk and memory of the running VM is committed.
- It creates a set of delta files where any new writes with the VM is performed.
- It frees up the virtual disk so that the files can be copied or backed up.
Once this is completed, you can copy the raw virtual machine disk's memory and configuration files to another machine and back them up from there.
After the VM files have been copied, you will then commit the delta back into the virtual machine.
No files need to be deleted if the above steps are followed.
