Safekeep is a tool for making incremental backups, written in Node.js.
Installation through NPM:
$ npm install -g safekeep
$ safekeep <source> <destination>
Requires .safekeepignore in the <source> directory or a parent directory.
A <destination> directory might look something like this:
~/backups
├── back-2015-09-13.10-04-05
├── back-2015-09-13.10-41-09
├── back-2015-09-13.14-23-56
├── back-2015-09-14.17-33-27
├── back-2015-09-15.16-12-06
├── back-2015-09-16.08-56-24

├── back-2015-09-19.22-02-52
├── back-2015-09-19.22-03-50
└── current -> back-2015-09-19.22-03-50/
Each time safekeep is run, a timestamped backup is made with the convention back-YYYY-MM-DD.HH-mm-ss, as well as a link called current -> which points to the latest backup.
Any changes made to <source> are incrementally backed up.
