i am facing an issue with a KVM container which has been incompletely backup
on last Tuesday (August 30th). last week this machine was
backup successfully. but this week it stuck. the process of this backup job
can bee seen here.

 Warning: bad ps syntax, perhaps a bogus '-'? See

this process has been stuck for a week which has been initiated on August

No error message can be seen in VZDUMP log.
