Point-in-time recovery allows database administrators to recover the database to a specific point in time, either via an SCN or timestamp value, instead of the most recent transaction. In this video, learn the principles of point-in-time recovery and the types of database failures where it can become essential to perform point-in-time recovery for your database.
- Let's take a closer look on how…Point-In-Time-Recovery is performed in an…oracle database using a combination…of the database backup and the database…archive redo logs.…Let's start our imaginary day at 12 PM.…I actually wish this was always the case,…but anyway, let's say we performed the…full database backup precisely at 12PM.…That's the first thing we did when…we arrived at the office.…A couple of hours have passed,…and it's now 4PM.…
So we took another database backup.…We are diligent DBAs, so we take regular…backups of our oracle database.…After the second backup has completed,…we now have one database backup from 12PM,…and another database backup from 4PM.…Some more time has passed, and it's now 8PM.…Hopefully, we are not in the office anymore,…but, nonetheless, we get notified about…a major database failure which have occurred…and we need to restore our oracle database.…
We immediately take a look at our…database backups and see that we only…have backups from 12PM and 4PM.…So if we use the 4PM backup to…restore our database,…
