KB5007: How to troubleshoot missing scheduled backup?

Below are the steps to follow for troubleshooting problem with missed schedule backup:

• Computer shutdown or hibernated
  Was the affected computer switched off, hibernated or in standby mode?
  
  Check if the affected computer was switched off, hibernated or in standby mode when the scheduled backup is due to run (e.g. computer shutdown after office hour, but backup schedule configured to a time after office hour).

• Patch the CloudBacko application to the latest stable release
  Are you using the latest version of CloudBacko?
  
  Ensure that the CloudBacko application is running on the latest stable release, to rule out issues that are already resolved.
  
   

• CloudBacko Services
  Was the CloudBacko Service started?
  
  Ensure that the CloudBacko Service are started or can be started properly

• Run scheduled backup on this computer setting
  Was the backup schedule setting configured properly?
  
  Ensure the 'Run scheduled backup for this backup set' setting is enabled.
  
  Launch CloudBacko user interface, select Backup Sets, then the corresponding backup set, and Backup Schedule to confirm.

• Timezone setting
  Is the timezone setting configured properly?
  
  Ensure that the timezone setting of the corresponding backup account is correctly configured.
  
  In some cases, a missed backup job alert is received for a backup job that was actually performed at the scheduled time (but at an incorrect time).
  
  For these cases, check if the timezone setting of the corresponding CloudBacko machine is correctly setup.

• CloudBacko installation on Linux
  Did you run the RunConfiguator.sh script on the affected client computer?
  
  For CloudBacko installation on Linux, you must configure the client login setting by running the RunConfigurator.sh script at least once.

• Java heap size setting
  Did the client application ran out of memory?
  
  Ensure that there are sufficient free memory available on the CloudBacko machine for the backup to begin.
  
  Increase the memory allocation setting with the instructions provided in the following KB articles:

Important:
We would just like to clarify that missed backup may not necessarily be a software problem.

End-users may have their PC / server switched off, hibernated, or in standby mode when the schedule is due to run, or the network can be unavailable or being cut off during the scheduled backup time.

We have also seen cases where the system clocks of the CloudBacko machine is off.
