YodaNote features cloud-based notebook snapshot of the disk, far as I know, is similar notes software first.
Notebook snapshot You can do the following:
A snapshot of your laptop will be a full backup, you can depend on your cloud disk size changes to your notes, create any snapshots, snapshot only takes up your cloud disk space does not take up your hard drive.
A month A day A year generated snapshots, you are in N, N, N, you can switch to the snapshot A year A month A Day, and then switch to the latest.

Notes version of history and notebook snapshot feature is consistent, that is, you save N snapshot, so that the notes will be up to (N 1) (N version snapshot + current latest version) and, of course, for the new notes may only one version.


Note: Snapshot for view, switch to the snapshot Do not modify the notes and synchronize, otherwise it will cause confusion in the content of your notes.

Note: The snapshot will only Full backup cloud disk version, certainly can not be used if you do not set the cloud disk, but before the new snapshot, manually make sure that has been synchronized.
