Yes. There are several ways to do it. On being your own scripted snapshot
method. Some companies use this method as their primary backup method.
They do not backup the files within the VM at all.

VMware offers Consolidated Backup addon, which is supposed to aid
commercial backup software vendor products in doing (essentially) the
same.

It is your choice to deside how you do it.
