Snapshots can be used to restore file(s) lost between an hour and one month.

 

The section below describes how to retrieve files saved in the snapshot directory.

 


Snapshots

Home Directories

A snapshot of your home directory is periodically taken.

 

At a terminal prompt, type:

 

cd .snapshot

If you type:

 

ls 

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

 

E-mail

 

A snapshot of your e-mail is also taken periodically

Contact Math Help if you need to retrieve e-mails.  We cannot guarantee that specific e-mails will be there due to the scheduling of backups.
