Eclipse has a very excellent feature called Compare with Local History, which allows you to compare all files in the workspace with previous versions. This is very useful for restoring old versions, even if they are not in the original control system, and this works because Eclipse saves snapshots of all files when they are saved.
Eclipse (default) supports up to one week, up to fifty changes and up to 1 MB of snapshot data for each file.
On a Mac, you also have Time Machine backups that instantly back up every file once an hour, saving hourly snapshots for a day, daily snapshots for a month, and weekly snapshots until you run out of disk space.
Is there an Eclipse plugin to use Time Machine data for local history outside of the copies that Eclipse stores?
