PLAT-ALM occurs overnight
when a scheduled CM backup fails to runovernight

Sometimes a PLAT-ALM error occurs when a scheduled backup fails overnight.


Notice the one that failed at 4 am. This can be viewed under Data backup/restore in the CM web GUI:



Sometimes a backup fails because it cannot reach the intended server that is receiving the backup, perhaps due to a brief network outage at that time. This is under Backup History, Check status of the last backup image:


We can also check the backup history on any CM or AAM server with the backup -t command

dadmin@sigavayacm1> backup -t | less

If the network outage is momentary, you can re-run the scheduled backup immediately and check to make sure it was successful.
