S3QL is a file system that stores all its data online using storage
services like Google Storage, Amazon S3, or OpenStack. S3QL
effectively provides a hard disk of dynamic, infinite capacity that
can be accessed from any computer with internet access running
Linux, FreeBSD or OS-X.
S3QL is a standard conforming, full featured UNIX file system
that is conceptually indistinguishable from any local file
system. Furthermore, S3QL has additional features like compression,
encryption, data de-duplication, immutable trees and snapshotting
which make it especially suitable for online backup and archival.
S3QL is designed to favor simplicity and elegance over performance and
feature-creep. Care has been taken to make the source code as readable
and serviceable as possible. Solid error detection and error handling
have been included from the very first line, and S3QL comes with
extensive automated test cases for all its components.
