How can I select where to save snapshots?

I have looked through the settings and documentation… But I can’t find out where I can select the location to save snapshots… Supposedly this is a feature, right?
How can I do this?
Thanks

No. Do you understand that CTM is not a backup tool, don’t you?
Also, that the snapshots aren’t into a file…
CTM uses the free space of the disk (in fact, all the disk) to “map” the use of the disk and save this map. The disk sectors are what is saved.
