I use a virtual machine for PLC programming. I want to keep a full image backup of this machine in case something happens. Currently I backup the VMDK files using automated backup software and it takes forever due to the size.
What could I do to keep a fairly up to date backup without coping over 90gb of vmdk files 4gb in size that each seem to change so the backup software recopies them. If I did smaller VMDK files would some of them not change every day? What other options are there?
