- Yes, CrashPlan encrypts the data to be backed up. Code42 regards data security as the most important component of their backup services, that's why CrashPlan encrypts your backup files before any data is sent to your backup destination.
- If you have never used CrashPlan at MIT, choose “New Account.”
- If you’ve already used CrashPlan and are setting up additional devices or computers, choose “Existing Account.”
|If you have have never used CrashPlan at MIT and you choose "Existing Account", you will get an error after you enter your username and password: "The information you entered is incorrect". The solution is to select "New Account"|
- You can backup up an unlimited amount of data for up to 5 devices/computers.
- Yes. This is how our CrashPlan installation knows you are a member of the MIT Community. Your Kerberos Username and password are not stored within the CrashPlan software, on the server or the client and are not stored with your data in the cloud. The CrashPlan application passes authentication over to MIT’s authentication servers to verify that your Kerberos Username and password combination are correct.
- Your first and subsequent backups are automatically started once you have installed CrashPlan on your computer.
- CrashPlan will pause and resume as needed when you shut down your computer or when it goes off of the network.
- The backup will resume when you boot up or resume your computer.
We sometimes see problems with the "cache" that CrashPlan uses. See:
- By default, all “user” directories will be included in the backup. This includes /Users/yourUsername or \Users\yourUsername.
- Information on backing up other directories in available here: https://support.code42.com/CrashPlan/6/Configuring/Change_the_file_selection
- Questions? Contact the IS&T Help Desk.
- IS&T has done extensive testing of CrashPlan and has chosen the best options for our community, based on our experience and findings.
- For additional information or specific questions, contact the IS&T Help Desk.
- Crash plan backups up by default every 15 minutes.
- This is the recommended setting, however if you would like to make an adjustment, contact the IS&T Help Desk.
- What you’re actually quitting is the CrahsPlan client software management console.
- The CrashPlan program that does the backup is a service that will continue to run in the background, even when the software management console is closed.
- Adoption should only be performed in certain circumstances. Please contact the IS&T Help Desk to discuss whether or not adoption is necessary in your situation.

How do I backup multiple users sharing one machine? Example: I've got a number of machines that are shared with multiple users. Even though no one user "owns" the machine, I need to make sure they're being backed up with CrashPlan.
- This is something the Help Desk can assist with. We can create a CrashPlan service account, one per department, for machines that no one owns. A CrashPlan service account uses a restricted Kerberos username. it can be used to backup as many devices (more than 4) as needed. Please contact the IS&T Help Desk to request a CrashPlan service account.
- Unfortunately, functionality is not available for accessing a backup from a non-MIT individual CrashPlan account. Backups cannot be transferred from one account to another account. Your CrashPlan account is dependent on your Kerberos username. When your Kerberos username is deactivated, you CrashPlan account is also deactivated and the backup data is deleted after 30 days.

Some department admins may have configured reports for you, and you may or may not be able to edit them. If you have questions about report settings you are unable to change, consult your departmental IT staff.

Why is my backup percentage so low in my reports? Am I not backed up? Why isn't my backup finishing?
Don't be fooled by low percentages. If a report runs while CrashPlan is performing a full file verification scan, your Backed Up % may display a low percentage. Your backup is still okay! The next time the report generates when the scan isn't taking place, the percentage will reflect the actual percentage complete.
