Do we have any Backup validation in Cocuhbase?

We have cbbackupmgr to take backups in Couchbase, also I have gone through all the possible attributes with this command but didn’t find any backup validation process or command.

Can any one please provide me more details on this?

In the command set, all you really have is list - https://docs.couchbase.com/server/6.5/backup-restore/cbbackupmgr-list.html

The truly only way to “verify” a backup is to restore it to a lower environment at this time.
