It means you can restore the database to it's status at a certain time you specify (the point in time). For example, if you know you system was stable at 7:00 am but some corruption occurred after that but you don't know exactly when, then restore it to how it was at 7 am.

Enables point-in-time recovery
It means you can recover the data up to certain point, now that point can be up to the failure or the user can also specify the time.

1. Restore to the Point of Failure  
2. Restore to a Point in Time

1 . Restore to the Point of Failure

RESTORE LOG PawanDB FROM <backup_device_name> 
WITH NORECOVERY;

Open in new window

2. Restore to a Point in Time

RESTORE LOG PawanDB
FROM PawanBackups
WITH FILE=4, NORECOVERY, STOPAT = 'Mar 15, 2025 11:00 AM';

Open in new window

Hope it helps !!
