First pass at tests comparing rsync to backrest. Decent results, but room for improvement.
...
All tests local over SSH with rsync default compression, 4 threads and default compression on backrest. Backrest default is gzip = 6, assuming rsync is the same.
On a 1GB DB:
rsync time = 32.82
backrest time = 19.48
backrest is 171% faster.
On a 5GB DB:
rsync time = 171.16
backrest time = 86.97
backrest is 196% faster.

v0.50: restore and much more
...
* Added restore functionality.
* All options can now be set on the command-line making pg_backrest.conf optional.
* De/compression is now performed without threads and checksum/size is calculated in stream. That means file checksums are no longer optional.
* Added option `--no-start-stop` to allow backups when Postgres is shut down. If `postmaster.pid` is present then `--force` is required to make the backup run (though if Postgres is running an inconsistent backup will likely be created). This option was added primarily for the purpose of unit testing, but there may be applications in the real world as well.
* Fixed broken checksums and now they work with normal and resumed backups. Finally realized that checksums and checksum deltas should be functionally separated and this simplied a number of things. Issue #28 has been created for checksum deltas.
* Fixed an issue where a backup could be resumed from an aborted backup that didn't have the same type and prior backup.
* Removed dependency on Moose. It wasn't being used extensively and makes for longer startup times.
* Checksum for backup.manifest to detect corrupted/modified manifest.
* Link `latest` always points to the last backup. This has been added for convenience and to make restores simpler.
* More comprehensive unit tests in all areas.
