I have an Ubuntu VM with 3 partitions. One is the main partition, one is a small swap-space partition, and the last is a 3rd partition with 20 GB of storage space.
I imagined these 3 would be separated into 3 .vmdk files, so it would be a nice modular file format. However, I go look and I have 22 .vmdk files! What are all of these? And is there any files that separate the 3 partitions? For example, if I keep backups of my VM and want to revert to a months old version, but keep my current 3rd storage partition, is there a single file with this that I can keep?
