Backing up a SQLite database file on a regular basis can quickly become really heavy! Indeed, the total weight of your backup will be (database_size * num_backups).

With an incremental backup system, only the difference since the last snapshot is saved!

So we end up with a lightweight save, including multiple snapshots to rollback to any state of the database.

This library is a cleaned up and TypeScript adapted version of sqlite3-incremental-backup by nokibsarkar, which was itself built after this StackOverflow discussion.
