Per-directory archive of directory contents
Original directory hierarchy is preserved for easy location of backed up files
No limit on directory hierarchy restoration, eg. you can restore only one path thats 3 levels deep
Wide range of compression support, including xz, bzip2, gzip and no compression at all
Parallelized compression support
RSync friendly as archives are only updated if need be, eg. new files are added to a new archive if old files did not change
