+Garage is an S3-compatible distributed object storage service designed for self-hosting at a small-to-medium scale.

+Garage is designed for storage clusters composed of nodes running at different physical locations, in order to easily provide a storage service that replicates data at these different locations and stays available even when some servers are unreachable.
