Backup Retention Policy For Inactive Cloud Destinations

Applies to:
  • CrashPlan for Home


Computers that back up to CrashPlan for Home's secure online backup destination, CrashPlan Central, must connect to CrashPlan Central at least every 180 days (6 months). After 180 days of inactivity, backups stored on CrashPlan Central are deleted and cannot be restored. This article describes the backup retention policy for inactive backups stored on CrashPlan Central.

This policy affects only backups that use CrashPlan Central as a destination. This policy does not apply to backups sent to other destinations, including your own external drives, friends' computers, or other computers you own.

For our policy on expired subscriptions, see Backup Retention Policy For Expired Subscriptions And Trials.

CrashPlan Central retention policy

We recommend keeping your computer powered on, connected to the internet, and backing up to CrashPlan Central regularly in order to maintain a healthy backup. If a computer has not connected to CrashPlan Central for 180 days (6 months), we may remove the backups for that computer on CrashPlan Central.

Before we remove any backups on CrashPlan Central, we send a notification to the email address associated with your CrashPlan for Home account. This notification shows which computers' backups are scheduled for removal from CrashPlan Central. You can identify your computers in the Account tab of the CrashPlan app or the computer details in the CrashPlan web app.
