Armadillo is an XML based secure backup script for AWS S3. It gathers any files and folders you specify, archives them, encrypts and/or signs them using GnuPG and finally uploads them to your S3 bucket. For more details see the comments in demo-config.xml and armadillo script.
I originally wrote Armadillo to explore newLISP as an alternative to python shell scripts and to have a small utility that would encrypt my backups before beaming them to S3.
Armadillo is very much still in an alpha stage and I haven't used and/or tested it much beyond my personal use.
