1 Burp is a network backup and restore program. It attempts to reduce network
2 traffic and the amount of space that is used by each backup. There are two
3 independent backup protocols to choose from:
4 - Protocol 1: Optionally uses librsync.
5 Available in all burp versions and is stable.
6 - Protocol 2: Uses variable length chunking for inline deduplication, and
7 sparse indexing on the server side.
8 Available from burp version 2.0.x, but is experimental and should not be used
