- 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 applies only to 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.
Any warnings in your backup status report about data removal from local destinations actually reference CrashPlan Central (cloud) backups only. This issue will be resolved in a future release.
For our policy on expired subscriptions, see Backup Retention Policy For Expired Subscriptions And Trials.
CrashPlan Central retention policy
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. Backups sent to other destinations (including your own external drives, friends' computers, or other computers you own) are not affected.
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.
Keeping your old backups active
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.
To prevent the removal of your backup from CrashPlan Central, you can either:
- Reconnect your computer or connect a replacement computer to the backup on CrashPlan Central.
- Restore any file from your CrashPlan Central backup using the CrashPlan app, the CrashPlan mobile app, or the CrashPlan web app.
Either of these options resets the 180-day counter for activity on your backup. If your computer is not regularly connected to CrashPlan Central, you may need to take action again after another 180 days has passed.
Verifying your computers have recently connected
You can verify that all your computers have recently connected using the CrashPlan web app. From the Computers tab, locate the Last Connected time.
