SCS Data Protection Service FAQ

About

The SCS Mobile Data Protection Service syncs up your data anytime your laptop is connected to any network. There is no need to be on the SCS or Carnegie Mellon network to protect your data. Unlike archived backups (TiBS), this is a data protection service that will only sync data from your user profile. For more detailed information about this service, see the Data ProtectionService page. The data protection system used is Code42 CrashPlan. Here are some frequently asked questions (and answers) about the SCS Data Protection service. Contact the SCS Help Desk at help@cs.cmu.edu if you would like assistance or have any additional questions.

Frequently Asked Questions

  1. How do I subscribe to have my data protected?

    To subscribe to have your data protected, email the SCS Help Desk at help@cs.cmu.edu with the asset tag of the laptop you would like to subscribe. Please note that if your computer is not subscribed to any other support services you will need to provide a valid oracle string with your request.

    For more information about the support charges for this service, please see the machine charges page.

  2. Is my mobile device eligible for this service?

    Any mobile device that is running one of the operating systems supported by SCS Computing Facilities is eligible for this service. Unlike archived backups (TiBs), network and software support are not required to enroll in the Mobile Data Protection Service.
  3. How can I determine if my data is being protected?

    You should see an icon in your system tray or task bar for the Code42 Crashplan client, or you can start the client manually through the Start menu. On the main client page, click on Tools/History and it will show the last time the client successfully copied files to the server.

  4. Which files are protected by this service?

    All files that are located in the Users folder are automatically defined to be synchronized to the server for backup. In addition, all files in your user profile are copied, as well as certain system and application settings. File types that are not synced are:
    • .vmdk
    • .dmj
    • .iso
    • .vmem
    • .vmsn

    Note: Linux CrashPlan backs up the user home directory (/usr0/home/$USER on Dragon systems).

  5. Is there a limit on the amount of data that can be protected?

    Currently, there is no limit of data per person.


  6. How does this service differ from traditional backups?

    Unlike traditional backups, this is a data protection service that will only sync data in your user profile. The SCS Data Protection service does not back up system files. Restores initiated using this service cannot be used to restore/rebuild a broken computer.

  7. Can I limit how much network and CPU is used by this service?

    The amount of network bandwidth and system CPU consumed by the client can be adjusted from the "Tools/Options" page in the Code42 Crashplan client. We recommend that you not change these settings unless directed to do so by SCS Computing Facilities; changing these settings may prevent the Data Protection Services from working correctly.

  8. How do I restore my data?

    You can restore data that has been copied to the SCS Data Protection server yourself using the Code42 Crashplan client.

    To perform a restore using the Code42 Crashplan client, open the Code42 Crashplan client by right-clicking on the icon in the task bar (or though the Start menu). Select the "Get Files" option from the main client page. You will be shown a directory listing of all the folders and files that are available on the server, along with a series of possible "restore points", which are the times that the data was copied.

    You should select the file(s) needed and the version of the data and select “Get Files”. You will then be prompted to choose the destination for the file(s) to be copied to.

  9. How long will my data be protected?

    Currently there is a 6 month data retention period. The most recent copy of your synced data will always be available as long as you are subscribed to the service.


  10. If my laptop crashes, can I use this service to restore my documents? Yes. The Data Protection Service backs up all files under "My Documents" and other similar locations. You can use the Code42 Crashplan client to restore your files to another computer.
  11. If my laptop crashes, can I use this service to restore my operating system?

    No. The SCS Data Protection Service is not designed to do full system backups and restores.
