Burp is a program that backs up and restores data. It uses librsync in order to save on the amount of space that is used by each backup. It also uses VSS (Volume Shadow Copy Service) to make snapshots when backing up Windows computers.
This release adds multiple retention periods (e.g, keep 1 backup per day for 7 days, 1 backup per week for 4 weeks, 1 backup per 4 weeks for a year). See the 'keep' option in the man page. A network send rate-limiting feature was added. There are small bugfixes.
