If you don't do anything more than open Parallels, resume your
VM, then suspend the VM and quit Parallels, the monolithic VM
container file will still have been modified, and that will cause
CCC to recopy it. Compare the following two tasks:
Run a CCC backup
Run the same CCC backup task again -- expected result: not a
lot of data will be copied, probably less than a few hundred
Launch Parallels and start your VM
Close the VM and quit Parallels
Run the same CCC backup task -- expected result: The entire VM
container will be copied because it was modified.
Unfortunately there isn't a lot that you can do to avoid this,
the Parallels VM container file is monolithic and it changes every
time you use the VM, even if you don't think you're making changes
Some people create separate backup tasks for their Parallels VM,
e.g. exclude it from the general backup task, then use the "Choose
a folder" options in the Source and Destination menus to back up
just the Parallels folder on a separate schedule.
Thanks for getting back to me so quickly. I do have one more question though.
When CCC recopies data in Parallels, does it 'write over' or does it 'add to'
the Parallels data already backed up previously? If the latter, then I'd have
two copies of basically the same data.
PS If CCC restores data as easily as it clones it, you have one tremendous

It depends on your settings. If you choose the "Temporarily
archive modified and deleted items" preset, CCC will move the older
version of the Parallels VM file aside to an archives folder, then
copy the newer version. If you use the preset to "Delete anything
that doesn't exist on the source", then the older version of the VM
file is simply overwritten.
