How do I retrieve lost or deleted files?

A snapshot of your home directory is periodically taken.
At a terminal prompt, type:
cd .snapshot

If you type:

You will see a list of directories:
./         hourly.1/  hourly.4/   nightly.1/  nightly.4/  weekly.1/

../        hourly.2/  hourly.5/   nightly.2/  nightly.5/  weekly.2/

hourly.0/  hourly.3/  nightly.0/  nightly.3/  weekly.0/

hourly.0 contains the most recent backup.

Search through the directory to find your lost or deleted file.

When you are finished, you can copy it to your current home directory by typing:

cp file /my/home/directory
