There are two features that I need that are difficult to setup with most backup systems.

    1. Does this support encryption? 
    2. Can this do one-command restore of files to a previous revision or day?

Yes and Yes.

Duplicacy follows the git/hg command model. To initialize the repository (the backup to be backed up), run the init command:

  duplicacy init repository_id storage_url -e

The -e option turns on the encryption.

To backup:

  duplicacy backup

To restore:

  duplicacy restore -r revision_number [files]
