Symptom:

A client/clients do not run a scheduled backup

A manual backup appears to run successfully.
No scheduled backup appears under Server > Scheduled Backups for the affected client.
Things to Check:
  • Make sure the client has a schedule enabled under Clients > Edit (you can also see this information under Clients > Summary under the "Schedule" Column)
  • Look over the schedule under Clients > Schedules to confirm the schedule has the proper schedules configured for backups
  • Check the CFA time under System > Status and change it to match the servers if needed by going to System > Settings > Time
Resolution:
This issue is commonly attributed to something getting hung up during the initial client configuration.
If none of the above steps resolve the issue, it is recommended to create a new client and test to see if the same behavior is observed with the new client.
Also, you may try applying the different schedule to the client, click Apply, then Activate Configuration, apply the required schedule, and activate it.
