Problem
The user receives an email warning or alert stating that a computer has not backed up to any destination for a specified number of days.
Environment
- CrashPlan app
Cause
Alerts and warnings are sent automatically when a backup has not occurred within the configured time period. By default, warnings are sent after three days of inactivity, and alerts are sent after five days. This can be caused by network connectivity issues, the device being powered off or asleep, background service errors, or restricted backup schedule configurations.
Resolution
- Verify that the computer is turned on, awake, and connected to the Internet.
- Open the CrashPlan app and check for any app status messages, such as "Unable to connect, check your network."
- Select Settings.
- Select Backup Sets.
- Click Change next to the backup schedule.
- Set the schedule to Always keep up to date, or verify that the computer is awake during the time window configured for backups.
- Restart the CrashPlan service or restart your computer to resolve potential connectivity issues.
- Trigger a manual backup to verify the issue is resolved and to reset the alert period.
