Although not open source, CrashplanPROe only costs $365 for a perpetual five client license. I use it to backup some of my Linux boxes. It has very good deduplication, compression, and encryption. For example I have 1.7TB of data on one linux system and another system that has 1.5TB. I NFS mount one of the systems to another and only use one Crashplan client to backup both data sets to a single backup archive. The backup archive is only 1.2TB and that also spans 90 days worth of file modification and deletion I can recover.
