Scheduled backups for VEs that are using particular schedule are not performed after specific date. One might find multitude of exceptions of the following kind in vps.log:

ERROR ClusterImpl [QuartzScheduler_Worker-7] - Failed to save pipeline #4880 [(VE_BACKUP for: VeId[1308432.example]), created at node [im1], step 0 (<start>), mode: EXEC, state:SHARED_RUN, reqIs: null] java.lang.StackOverflowError: null

        at com.esotericsoftware.kryo.Generics.getConcreteClass( ~[kryo-3.0.0.jar:na]

Scheduled backups for VEs for other schedules are performed correctly.


CCU-14645 damaged database caching layer during handoff of VEs. That resulted in exceptions (of the same kind) during VE_BACKUP procedure which lead to appearance of entries in the database, that are not cleaned-up automatically, but are considered as active backups.

Therefore, the task that scheduled backups does not place more backups in queue.


CCU-14645 was fixed in OAP version 7.2. Update is required in order to resolve the issue permanently.

In order to apply the workaround, please contact Odin Technical Support.
