ignis

Ignis does not use packet writing anymore as it is
not 100% stable under current Linux kernels. It
now burns multiple sessions onto the medium. Big
changes a small enhancement were also done:
archives can now be split into more than one file
(avoiding the 2GB limit per file on DVDs).

Everything that's written onto the medium is now checked against the md5 sum of the original data. Signing with a private key is now possible. The metadata is now encrypted/signed and/or stored with the same compression as the data. Initial work on the recovery tool has started, e.g. it is now possible to search for a file and get a list of all available versions on the media. An option has been added for ejecting the medium before each use, for bad braindead hardware. UDF formating allows you to choose the type of UDF fs. There are many bugfixes and better error handling.

tar, tar.gz, and tar.bz2 backup methods are now supported. gpg can be used for symmetric or public key encryption. A new metadata system was implemented, which will make it possible to search for files without inserting the mediums. The configuration used to perform a backup is now also copied to the medium so that ignis can be recovered after a hard disk failure.
