Add or remove a computer (Small Business)


This article provides step-by-step instructions for adding a new computer to or removing an existing computer (also known as device) from your CrashPlan for Small Business account. Adding all your business's computers to your CrashPlan for Small Business account helps ensure all your data is protected. 


  • CrashPlan for Small Business subscription pricing is based per device, so each month you are only billed for the number of active devices in your organization. 
  • After adding a new computer, you can begin backing up files for that computer. 
  • When you remove a computer from your account, the CrashPlan app stops backing up its files and permanently removes all its backed-up files. If you want to back up the computer again later, you must restart your backup.

Add a computer

Before you begin

 Use unique email addresses and passwords

Each person using CrashPlan for Small Business needs their own user account with a unique email address and password. Sharing a user account among multiple people is a large security and data privacy risk because any person using the shared account can download backed-up files from every device under that user account.

Step 1: Download the CrashPlan app installer

 Placing an installer on each device

Most CrashPlan for Small Business administrators prepare to install the CrashPlan app using one of these methods:

  • Download the CrashPlan app installer once, then copy the installer to multiple devices.
  • On each device, download the CrashPlan app installer from the CrashPlan for Small Business CrashPlan console.
  1. Sign in to your CrashPlan for Small Business CrashPlan console with your CrashPlan for Small Business username and password.
  2. Go to Downloads.

    Most Windows devices will use the Windows (64-bit) installer.

Step 2: Install CrashPlan for Small Business and sign in

Each user installs and signs in to the CrashPlan app using their own username and password.

  1. Run the CrashPlan app installer on the device where you want to install CrashPlan for Small Business.
    • Windows: Double-click the MSI file.
    • Mac: Mount the DMG and double-click the PKG file.

  2. After the installation is complete, sign in to the CrashPlan app using your CrashPlan for Small Business username and password.
    If you don't have a username and password, your CrashPlan for Small Business administrator can create them.

Step 3: Start backing up files

  1. (Users with other devices on the same user account only) The message Looks like this device is signing in for the first time appears. Click Add New Device and then click Yes on the confirmation dialog. 
    The new device appears on the Home screen.
  2. Click Add destinations.
    • To back up to the CrashPlan cloud, select CrashPlan PRO Online.
    • To back up to a local destination:

  3. Click Save.
  4. Click Done.
    Backup starts automatically.

Remove a computer

 Removing is permanent and can't be reversed

Removing a computer from your account deletes all of its backed-up files. This is permanent and cannot be reversed. Any previously stored backup information is deleted.

  1. Sign in to your CrashPlan for Small Business CrashPlan console.
  2. Go to Devices > Active.
  3. Click the device name for the computer that you want to remove.
    The device details screen appears.
