Files that still reside on your system are stored indefinitely on the backup server. Whenever a file is changed, a new version is captured and backed up every 15 minutes. CrashPlan stores a number of versions of each file, based on the age of the revision:

  • A 15-minute snapshot for up to 7 days;
  • A daily snapshot for up to 90 days;
  • A monthly snapshot for older than 90 days.

Files that you have deleted from your system are kept on the backup system for 90 days.

  1. Open the CrashPlan application. This can be found in your applications folder or program files.
  2. Sign in with your NetID and password.
  3. Select the device from which you want to restore files, click the Get Files button.
  4. By default the most recent versions of the files and directories will be restored. If you prefer an older version, click on "As of Today" to choose a different backup date and time.

  6. In the Get Files menu you will be able to select the destination, file name (if file already exists), and the file permissions. When you're ready, click Go.

9. Will running CrashPlan PRO slow down my computer?

Based on our testing we did not notice much performance impact from running CrashPlan PRO. CrashPlan  is configured to use very little CPU time while the user is using the computer. If you have an older computer and feel that you want to tell CrashPlan PRO to use even less CPU time while you are present you can modify the setting.

  1. Open the CrashPlan Pro application. This can be found in your applications folder or program files.
  2. Sign in with your NetID and password.
  3. Click on the Tools menu and select Options.
  4. In the Usage tab modify the "When the user is present, use up to X percent CPU". By default this is set to 30. Set it to a lower number to have CrashPlan PRO use less CPU time.
  5. Exit the CrashPlan PRO application. It will continue running in the background performing backups.

10. How long will it take for my initial CrashPlan PRO backup to run?

The initial backup time varies depending on the speed of the computer, the network connection, and the amount of data being backed up. In our testing a year-old computer plugged in to the campus network was able to back up 50 GB of data in four hours. Most computers left plugged in to the campus network and unattended should be able to back up overnight. Users backing up from the wireless network or a home network may take longer.

11. Does CrashPlan PRO work off-campus?

Yes. CrashPlan can perform backups of your computer from any location with an Internet connection.

12. How do I know that CrashPlan PRO is working?

  3. In the home section you will see the device(s) being backed up, click on Details to obtain the most up to date information regaring your device's backup.
  4. Exit the CrashPlan application. It will continue running in the background performing backups.

By default, CrashPlan sends you an email if it is unable to perform a backup for 3 business days.
