Options for versioned home directory?
 

I would like to switch my home directory over to a versioned system.

I have found a couple of ways to do this. However, I am having trouble finding a way that fulfills my one request: it must be transparent.

Source code control systems do almost exactly what I want, except the process of committing changes must be done manually. I'd also rather not have the commits run as a cron job. It seems like "versioning file systems" really support little more than snapshotting, and the snapshots would need to be done by a cron job (or manually.)

What would work best for me is to somehow mount a local Git (or svn, or ...) repository as a local filesystem such that commits are automatically done upon save. Is there a way to accomplish this?

Thank you for any help.

Not that it's necessarily the best solution, but have you taken a look at http://en.wikipedia.org/wiki/Ext3cow? Btrfs (still in pre-release stage) also supports versioning, if I recall correctly.

You might want to look at some fuse filesystems, I think there were a couple that did auto versioning

I know about Btrfs, but it appears that snapshots have to be explicitly created.

This appears to be exactly what I need.

Thank you.

Then mark the thread as solved (in Thread Tools).
