+
+Drops of glue between [SSHFS](https://github.com/libfuse/sshfs), [Borg](https://www.borgbackup.org/) and [cron](https://github.com/vixie/cron)
+
+## Features
+
+- Auto-mounts specified SSHFS as required
+- Encrypted, deduplicated backups thanks to Borg
+- Backup of specified directories to SSHFS
+- Daily cron scheduler
+
+## Usage
+
+Enter SSH credentials, host and destination directory in `/etc/tupper.conf`, as well as the directories to back up.
+
+Then either run `sudo tupper` or wait for the daily cron scheduler to kick in.
+
+## Building
+
+`dpkg-deb --build . tupper_0.1_any.deb`
