nightshift

nightshift implements a POSIX filesystem within a SQLite database using FUSE.

• Benefit from SQLite's renowned durability, portability and well-documented storage format.
• Encryption is handled by SQLCipher, a battle tested library built on top of SQLite. SQLCipher uses AES-256.
• Compression is handled by lz4, providing fast compression and decompression speeds
• Hackable project: the filesystem is implemented with simple SQL queries and a few tables

Example: backup files with mount-exec

The mount-exec command will mount the given database at the given path using the given key and then run the command given in the --cmd arg using the optional --arg arguments. Once the script exits, the filesystem is safely unmounted and nightshift will exits with a status that indicates if the script failed or not.

nightshift mount-exec --db /tank/data/backup.db --mount "$(mktemp -d)" --key-file /opt/backup/key.txt --cmd /opt/backup/backup.bash

Write a callback script to backup precious files inside of the mounted filesystem. Use any command you like inside the script:

# file: /opt/backup/backup.bash
#!/bin/bash

cp -r /tank/data/photos "$NIGHTSHIFT_MOUNT_PATH"

pgdump ... | gzip > "$NIGHTSHIFT_MOUNT_PATH/databases.sql.gz"

scp -r [email protected]:/data "$NIGHTSHIFT_MOUNT_PATH"

nightshift always sets the NIGHTSHIFT_MOUNT_PATH and NIGHTSHIFT_DB_PATH environment variables inside the callback script.

Why is it called nightshift?

Naming projects is hard. I was listening to the song Nightshift from the Commodores when I started this project. It seemed like an acceptable name at the time.
