Using the _backup from standby_ feature I could able to take backup from

take backup from primary.
This is entirely on purpose. Backup from standby is designed to reduce
load on the primary so we believe it is counter-intuitive to put load
back on the primary when the standby is down. Running backups *at all*
when degraded is usually a bad idea.

You can run more than one standby and pgBackRest will automatically
select the first one it finds that is up. If you must take a backup
when degraded then you can specify --no-backup-standby on the command
line to disable standby for that one backup.
