- Adopting Another Computer
- Adoption is the process of having one computer take over for another, which is used in circumstances such as: moving a backup to a new computer, replacing an old computer, replacing your computer's main hard drive, or recovering after an operating system reinstall. By reconnecting to the previous computer's backup archive, you avoid repeating the potentially lengthy, initial backup.
- Adopting A Computer With A Different Operating System Or File System
- Are you changing your operating system or file system on your computer? Whether changing between Mac, Windows, Linux or even newer versions of the same operating system, adopting your existing backup can help you get started on your new system. By carefully following this tutorial, you can reconnect to the previous computer's backup archive, and avoid repeating the potentially lengthy initial backup.
If you are using CrashPlan PROe version 3.4.1 or earlier, see Adopting A Computer With A Different Operating System (3.4.1 And Earlier) instead.
- Adopting The Correct Archive
- When adopting a computer, you want to select the correct backup archive. In some cases, you might have an old archive that was forgotten or replaced. This article will help you identify which computer to adopt.
- Attaching An Archive
- When you back up files to a destination, CrashPlan creates an archive there. For all practical purposes, the archive is the actual “backup” of your computer.
If you need to restore from an archive on a local backup, but the archive is not listed as an available restore destination, follow the steps below to attach the archive.
If you are a CrashPlan PRO user, please see Restoring From An External Drive (PRO).
Local Backups Only
Attaching an archive only applies to local backups, not to cloud destinations like CrashPlan Central.

- This tutorial explains how to change the email address associated with your CrashPlan account.
- Changing Your CrashPlan Password
- This tutorial describes how to change your password from the CrashPlan app, as well as how to request a password reset in the event that you lose or forget your password.
Tips For Creating A Secure Password
We recommend using a password that is at least eight characters long. Your password must use a minimum of five characters.
We recommend using at least two numbers (123) or symbols ($%^).
Choose a password that is easy to remember, because you will need to supply the password to manage your CrashPlan account or to change your password.
Don’t use items that are easy for someone else to guess, such as names, words, dates, or your ATM PIN.
Less Secure Passwords:
More Secure Passwords
Change Password From The CrashPlan App
If you know your current password, you can change it directly from the CrashPlan app.
Open the CrashPlan app and go to Settings > Security
Enter your Current Password
Enter your New Password, then re-enter it below
Request Password Reset
CrashPlan for Home and CrashPlan PRO only. If you use CrashPlan PROe, contact your CrashPlan administrator to have your password reset.
If you lose or forget your account password, you can request that it be reset.
Open a web browser and go to the password reset page for your CrashPlan product:
CrashPlan for Home
Enter the email address associated with your CrashPlan account
Note: You can view the email address associated with your account in the CrashPlan app from Settings > Account
Click Submit (CrashPlan for Home) or Reset (CrashPlan PRO)
Follow the password reset instructions sent to your email
Password Reset Link
The password reset link is time sensitive and will expire. If you do not see the password reset instructions in your email inbox, check your spam folders.
- Creating Backup Sets
- When you first start backing up, CrashPlan backs up everything in your home directory or user folder in a single, default backup set. With backup sets enabled, you can create additional backup sets so that different groups of files can back up to different locations and with different settings.
This tutorial includes important considerations as well as step-by-step instructions for creating backup sets. You can also copy, rename and remove backup sets.
- Deleting Files From Your Backup Archive
- CrashPlan allows unlimited retention of your backed up files, but there are times that you may want to delete files from your backup archive. This article explains ways that you can remove files from a backup destination or remove a backup destination entirely.
- Enabling Windows EFS Support
- In order to back up and restore EFS files, you need to run CrashPlan “as user” and set the proper permissions. This article describes how to tell CrashPlan to run “as user.”
The information presented here is intended to offer information to advanced users. However, Code42 does not design or test products for the use described here. This information is presented because of user requests.

- Excluding Networks Used For Backup And Restore
- The CrashPlan app allows you to exclude network adapters and wireless networks from use by CrashPlan. For example, this is useful if you want to prevent CrashPlan from:
Using a slow VPN connection
Backing up through a data card that could result in overage charges from your wireless carrier
This tutorial provides a step-by-step guide to excluding network adapters and wireless networks.
- Excluding Or Filtering Files Using File Type & Regular Expressions
- Certain files and file types can be globally excluded from a backup without having to modify the file selection by unchecking each individual file/folder. These exclusions can be added either by file type or by using regular expressions (regex). This tutorial explains how to configure your backup using both file type and regular expression exclusions.
- Installing CrashPlan on Windows Home Server
- If you intend to run CrashPlan on your Windows Home Server (WHS), please follow these instructions. Windows Home Server is not an officially supported platform at this time, and this guide is provided as a resource for those who would like to try this experimental procedure.
- Limiting The Disk Space A Friend Can Use For Backup
- Allowing other people to back up to you is a great way to help your friends protect their information. However, you may want to limit the amount of storage they can use for backup. This tutorial explains how to specify the amount of space friends can use.
- Moving And Renaming Files In Your Backup Selection
- You can move and rename files and folders on your computer that are already backed up. If you are moving or renaming files within your existing backup file selection, CrashPlan’s data de-duplication feature detects the change automatically. If you move files to a location outside of your backup file selection, then you must update your file selection.
This tutorial contains step-by-step instructions for moving and renaming files backed up by CrashPlan.
- Moving A Backup Archive To A New Folder Or Drive
- This tutorial explains how to move an archive from one local destination, such as a folder or external drive, to another local destination. When you change the backup location, CrashPlan moves the entire backup archive so that all of the archived files are in one place. This might be useful, for example, if you are backing up to an external drive that fills up and you want to move the backup to a larger drive.
- Pausing Backup Or Restore In CrashPlan
- This article describes how to pause the CrashPlan service for a specified period of time. Pausing the CrashPlan service temporarily stops inbound and outbound backup. In other words, you can't restore or back up files while the CrashPlan service is paused.
- Protecting Your Data After A Computer Is Stolen
- If your computer is stolen, you can take a few simple steps to protect your CrashPlan backup. This article describes best practices for protecting your CrashPlan backup after a theft, as well as next steps for recovering your data from a new computer.
Note: If you use CrashPlan PRO or CrashPlan PROe, and your computer is stolen, contact your CrashPlan administrator immediately.
- Removing A Backup Destination
- This article provides step-by-step instructions for removing a backup destination. You should remove a backup destination when:
A destination computer is no longer available for backup
You want to remove all of the files backed up to a destination from your backup archive
- Removing A Computer From Your Account
- This article provides step-by-step instructions for removing a computer from your CrashPlan account. When a computer is removed, you can no longer back up its files or use it as a destination for other backups.
- Renaming Your Computer Backup
- The CrashPlan app uses the information from your user account to assign a name for your computer. This tutorial shows how to change the name that CrashPlan assigned to your computer.
Changing The Computer Name
Your computer backup name is a label for you to distinguish one computer from another. The name itself has no effect on your backup. The name that you choose displays in email reports, CrashPlan web app, and within the CrashPlan app. You can change the name of your computer backup from several places, as described below.
From The CrashPlan App
Go to Settings > General.
From Name for this computer, enter the new name.
From The CrashPlan Web App
(CrashPlan for Home only)
Sign in to CrashPlan web app.
Select the computer's name that you want to change.
In the computer name field, enter the new computer name.
From The Administration Console
(CrashPlan PRO and CrashPlan PROe only)
Go to the administration console for the version of CrashPlan used by your business:
CrashPlan PROe: Contact your CrashPlan administrator for the administration console's URL (e.g., https://example.com:4285/console/login.html)
Click My Profile.
Select the computer's name that you want to change.
Click the action menu.
Next to Name for this device, enter the new name for the computer.
- Setting An Archive Question
- An archive question is an optional feature of the archive key password security option (displayed as 448-bit encryption + password in the security settings). The archive question can be used to reset your archive key password in the event that the existing password is lost or forgotten.
Note: The archive question feature is available in versions 3.6.1 and later of the CrashPlan app
- Signing Out Of The CrashPlan App
- This tutorial explains how to sign out of the CrashPlan app. You may need to sign out if you have changed your account information, you have two accounts, or if you are accessing your account from someone else's computer.
- Upgrading CrashPlan Security
- This article explains CrashPlan's default security setting, as well as recommendations and considerations for when it is appropriate to upgrade. Links to step-by-step instructions for upgrading are also provided.
No matter which CrashPlan security option you use, your backup files are always encrypted before any files are sent to your backup destinations. Encryption is the translation of data into a nearly indecipherable code, and it is the most effective way to protect your data. To view the contents of an encrypted file, you must have access to an encryption key that enables you to decrypt it. CrashPlan offers several options for securing this encryption key.
Note: If you are looking for in-depth technical details about each of our security options, please see our article on archive encryption key security.
- Upgrading CrashPlan Security To Archive Key Password
- Upgrading your CrashPlan security option to 448-bit encryption with password adds an additional level of security beyond the default setting. This article outlines the upgrade process and how to optionally add a security question to enable resetting the encryption key password.
- Upgrading CrashPlan Security To Custom Key
- Upgrading your CrashPlan security option to a custom key is the highest level of security available. However, it also requires the most management because you must provide your custom key when restoring data or installing the CrashPlan app on new computers. This article provides step-by-step instructions for upgrading to this security option.
- Using CrashPlan On A Headless Computer
- The CrashPlan app is designed with the assumption that the CrashPlan user interface and the CrashPlan service are running on the same computer. When the CrashPlan app is installed on a computer without a graphical environment, also called "running on a headless computer," the CrashPlan service must be administered from another computer.
Although running the CrashPlan service on a headless computer is an unsupported feature, this article describes a process that some users have found useful.
