At my old company we used NetApp, which supported a ".snapshot" feature. Whenever I did something stupid to my files, I could
cd .snapshot and find hourly and nightly directories which contain snapshots of my current directory. I get the file I need and resume my work.
Is there anything similar in the open source world?
I find many backup projects, but they generally backup to a different machine, with no easy access for the user. I find a couple user-space filesystems which operate on top of rdiff-backup, but is there a project that ties everything together into a cohesive system?
Thanks in advance.
