Modified rsync that used as part of BackupPC
Rsync-bpc is a customized version of rsync that is used as part of BackupPC, an open source backup system.
The main change to rsync is adding a shim layer that emulates the system calls for accessing the file system so that rsync can directly read/write files in BackupPC’s format.
Rsync-bpc is fully line-compatible with vanilla rsync, so it can talk to rsync servers and clients.
Rsync-bpc serves no purpose outside of BackupPC.
