But this needs the secret key on the backup server which I would like to avoid. It also introduces multiple points of failure and complexity.\r\n\r\nWhat about having an extract mode which uses the already existing local data for an in place diff recovery? This could make it pretty cheap to restore to an older state!\r\n\r\nI guess this could be one with the existing de-duplication algorithm as it is kinda \"reverse backup\"."},"comment":{"url":"https://api.github.com/repos/jborg/attic/issues/comments/117291127","html_url":"https://github.com/jborg/attic/issues/322#issuecomment-117291127","issue_url":"https://api.github.com/repos/jborg/attic/issues/322","id":117291127,"user":{"login":"ThomasWaldmann","id":356103,"avatar_url":"https://avatars.githubusercontent.com/u/356103?v=3","gravatar_id":"","url":"https://api.github.com/users/ThomasWaldmann","html_url":"https://github.com/ThomasWaldmann","followers_url":"https://api.github.com/users/ThomasWaldmann/followers","following_url":"https://api.github.com/users/ThomasWaldmann/following{/other_user}","gists_url":"https://api.github.com/users/ThomasWaldmann/gists{/gist_id}","starred_url":"https://api.github.com/users/ThomasWaldmann/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ThomasWaldmann/subscriptions","organizations_url":"https://api.github.com/users/ThomasWaldmann/orgs","repos_url":"https://api.github.com/users/ThomasWaldmann/repos","events_url":"https://api.github.com/users/ThomasWaldmann/events{/privacy}","received_events_url":"https://api.github.com/users/ThomasWaldmann/received_events","type":"User","site_admin":false},"created_at":"2015-06-30T18:25:33Z","updated_at":"2015-06-30T18:25:33Z","body":"Interesting idea!"}}
