Indeed, it's not straightforward to understand the difference between
Restore and Revert.
- Restore will restore a file/folder that you HAVE in a backup on your
disk. The important point is that you really need to have it in the
backup you are looking at.
- Revert doesn't need you to have the file/folder in the current
backup. It will dive into older backups till the last full one to find
your file/folder.

Let's take an example.

Full snapshot
     [Folder] => fileA(v0), fileB(v0), fileC(v0)
Inc Snapshot 1
     [Folder] => fileB(v1)
Inc Snapshot 2
     [Folder] => fileC(v1)

Then :
Restore [Folder] from Snapshot 2:
   *Result*: [Folder] => fileC(v1)
Revert  [Folder] from Snapshot 2:
   *Result* : [Folder] => fileA(v0), fileB(v1), fileC(v1)

So Revert gives you the state of the folder at a certain date, while
restore gives you the files stored at this date.
