An idea I have is implement simple versioning on the thaw folder. If edited the changes can then be reverted.

  And I have counter idea — encrypt N times, so every shadow copy is borked; certainly you are not storing "infinite" history?

    I presume the thaw folder would have an upper limit on storage, once hit you forbid writes entirely.

  Isn't that just a CoW filesystem? Just use e.g. ZFS and configure it to take regular snapshots (though you may want to be careful, a few years back if a zpool got completely full things got wonky, dunno if they've fixed it, so you may want to keep some disk space outside the zpool just in case, so you can expand the zpool enough to work if it gets completely full)

    OpenSolaris derivatives (eg OmniOS, SmartOS) are able to present the snapshots over SMB as windows previous versions. I have the server at work, which only has windows desktop clients, making 1-minute snapshots with a one-day lifetime in addition to daily, weekly, monthly etc. It's very handy for the occasions where you accidentally save over a document and slap yourself in the head immediately afterwards.
