Arq uses its own format. However, the developer of Arq has provided an open source restore tool on github: http://sreitshamer.github.com/arq_restore/ http://sreitshamer.github.com/arq_restore/ http://www.haystacksoftware.com/blog/2010/04/open-source-arq-restore-utility/ http://www.haystacksoftware.com/blog/2010/04/open-source-arq... Edit: the files on Github have not been updated in 3 months. So this most likely can't restore Glacier backups.
