eXdupe is a backup tool that performs data deduplication at a record breaking 900 MB/s (3 TB/hr) on 8 cores. It makes it simpler and easier to get started utilizing deduplication than it has ever been before.
You can also utilize deduplication in a simple file archiver way, outperforming gzip, bzip2, pigz, rar, lzop, 7zip, qpress, etc, second-to-none with respect to both speed and
compression ratio.

Full backup:
[-rfcqmgtps] <source files> <destination>
[-rfcqmgtps] <-stdin> <filename to assign> <destination>
<destination> can either be -stdout or a file. Use .full as file extension

Differential backup:
-D[rfcqtps] <source files> <.full file> <destination>
-D[rfcqtps] <.full file> <-stdin> <filename to assign> <destination>
<destination> can either be -stdout or a file. Use .diff as file extension

Restore full backup:
-R[fq] <.full file> <destination directory> [files]
-R[fq] <-stdin> <destination directory>
[files] is a list of files to restore, typed as provided by -L flag

Restore differential backup:
-RD[fq] <.full> <.diff file> <destination directory> [files]
-RD[fq] <-stdin> <.diff file> <destination directory>
[files] is a list of files to restore, typed as provided by -L flag
