Ahmed Mahmoud looks at point-in-time recovery and answers some frequently asked questions:
On some occasions, after the failover is initiated, the current Primary DR will start a new backup chain from that point and old backups are available on the current secondary DR. If we want to restore the backups which exists in Secondary it will not allow us to perform, apparently restore cannot be initiated on the Primary as the backup is not available.
Also, sometimes we observe in secondary DR for few databases, PitR restore point is available and for few databases it shows “no restore point available”
Read on to understand why that happens and what you can do about it.
