Re: [rdiff-backup-users] Enhancement request: other compression methods

[Mr. Clif]

+1 here,

by the way, it's highly desirable if your compression algorithm keeps 
changes localized so rsync can efficiently just transfer the 
differences. Right now gzip, and it's multi-threaded version pigz are 
the only compression utilities that provides this "--rsyncable" option. 
The others tend to change every block coming after the first difference.
