Crackup is a pretty simple, pretty secure remote backup solution for folks who want to keep their data securely backed up but aren’t particularly concerned about bandwidth usage.

Crackup is ideal for backing up lots of small files, but somewhat less ideal for backing up large files, since any change to a file means the entire file must be transferred. If you need something bandwidth-efficient, try Duplicity.

Backups are compressed and (optionally) encrypted via GnuPG and can be transferred to the remote location over a variety of protocols, including FTP. Additional storage drivers can easily be written in Ruby.

• Ruby 1.8.4+
• GnuPG 1.4.2+ (if you want to encrypt your backups)

The latest version of Crackup is always available via RubyGems:

gem install crackup

Or you can download it yourself:

• crackup-1.0.1.gem
• crackup-1.0.1.tar.gz
