Supporting multiple compression methods would be nice.
Also one idea is to allow using one compression method (or no compression) while actually doing the backup, and then have a separate tool, to be run on otherwise idle time, recompress the data using some other, slower algorithm to conserve disk space without making the backup process slower.

done while this would be useful, it hasn't happened, and making the bug list longer is hampering other things. --liw
