Snapshot HOWTO

From Earlham CS Department

The CS systems administrators maintain a snapshot system to provide live, self-service file restores to users. There are six hourly backups taken everyday at four-hour intervals, daily backups every day of the week, four weekly backups kept for a month, and then three monthly backups.

To access them, go to any ACL and cd into the /snapshots directory. Then cd into the backup level you want (you can use ls -l to figure out when the backups were taken), and then cd into quark/clients/users/$USER to access the backups of your home directory. You can then copy these files into your home directory on quark.

Example of use

If I wanted to restore my ~/.bash_profile file from last week, I would execute these commands:

  1. cd /snapshots/weekly.0/clients/users/skylar
  2. cp .bash_profile ~/
