Hey thanks for the answer!
frankly speaking I don't even remember why I asked that...
Generally is a good thing to have the choice for different (high speed or high ratio) compression algorithms,
eg: snappy http://code.google.com/p/snappy/

Keep it up with this simple and beautiful backup tool!
my windows users really appreciate the magic of having multiple "full" backups on the linux server :)

I searched a little bit and found the program lzma which behaves like bzip2 or gzip.

Install lzma and set:

compress=lzma
uncompress=lzma -d
postfix=.lzma

in the configuration file.

Remember: You cannot link to old backups after this change!

I think the questioner is not here any more, but maybe it's of interest for somebody else.

Sorry, sorry, sorry. I missed this entry - shame on me.

You can use any compression program you want, but it must support reading from STDIN and writing to STDOUT.

You cannot change the backup algorithm in one backup repository! (up to now).

I do not know which program in particular you mean (and if you're still interested in the answer).

Do you know an implementation of 7z which supports STDIN / STDOUT?

Regards, Heinz-Josef

Is it possibile to use the LZMA compression for archiving?
Can someone provide the necessary configuration?
thank you
