Tarsnap is a secure cloud-based backup service featuring client-side encryption and de-duplication created by Colin Percival. You will need to be a Tarsnap subscriber to use this software. The recommended cache directory for Slackware is /var/cache/tarsnap, but this can be changed in /etc/tarsnap.conf to suit your file scheme. Even casual backups may contain sensitive data! Before running the build, please take a moment to verify the source tarball. The Tarsnap website has instructions for checking your copy against the release hash and Tarsnap code signing key.
