vc-backup is a vc backend that uses backups for simgle-file version control.
vc-backup.el is part of GNU ELPA, and can be installed using
package.el.
To activate the backend, add
(add-to-list 'vc-handled-backends 'Backup t)
to your initialisation file. It is recommended to enable
version-control so as to have multiple versions of a file
accessible.
Bugs or patches can be submitted to my public inbox. Note that non-trivial contributions require a copyright assignment to the FSF.
This package is still young, so wishes, impressions and criticism are very appreciated. If you have anything to say, feel free to send an email to the aforementioned public inbox.
vc-backup.el is distributed under the GPL v3 license.
