This is a variation (clone) of the backup gem without Qiniu storage. The qiniu gem has a dependency on an old version of json, and this blocks the backup gem from being updated to more current versions of ruby. This variation removes the use of the qimiu gem and so removes Qiniu as a storage option.
Thus this variation of the backup gem can be used with more current versions of ruby. The version number has "a" appended as a clue that this is a variation of the orginal.
What follows is from the original Readme:
Backup is a system utility for Linux and Mac OS X, distributed as a RubyGem, that allows you to easily perform backup operations. It provides an elegant DSL in Ruby for modeling your backups. Backup has built-in support for various databases, storage protocols/services, syncers, compressors, encryptors and notifiers which you can mix and match. It was built with modularity, extensibility and simplicity in mind.
