Thank you for your email. Actually concern is while taking backup using pgbackrest backup got failed with an error message ERROR [082] : WAL segment was not archived before the 60000ms timeout and received the below error in PostgreSQL log. Could you please help in this regard?.

The most likely bet is that something set the system clock back a couple of seconds. Otherwise you've got rather bad clock skew between different processors in the system. This isn't particularly harmful so far as Postgres itself is concerned, but you might want to do something about it to avoid ending up with seemingly-inconsistent timestamps in your data.
I'm also curious about how come the log entry timestamp seems to be a couple of months older than the timestamps quoted in the message. There seems to be something wacko about timekeeping on your system.
