bup backups are 2.7 times smaller than rsnapshot

Zoran has been doing some interesting tests of bup space efficiency and import
performance vs. good old rsnapshot.

Lately, he's been working on an rsnapshot-to-bup importer tool.
According to his most
recent message, after importing the incremental backups from two
servers, the bup repo was 4.6GB vs. the original rsnapshot disk usage of
12.6GB. That's 2.7 times smaller.

YMMV. Results may not be typical. Always consult a physician.

And Also...

As of last night, you
can also restore your bup backups. Yeah, I know. It's that awesome.
