Transcript

Okay, the next topic is disaster recovery. Azure takes snapshots of your Synapse Analytics data warehouse throughout the day. Then if you need to restore your data warehouse to a previous state, you can simply choose which of the automatic restore points you want to go back to.

In some cases, you may want to create your own user-defined restore points in addition to the automatic restore points. For example, you may want to take a snapshot before you make a large number of changes to your data.

Both the automatic and user-defined restore points are stored in the primary region where your data warehouse runs, so if the primary region is down, you won’t be able to access any of those restore points. To ensure that you will still be able to bring up your data warehouse in another region, Azure makes a geo-redundant backup once a day to a paired data center. If disaster strikes, you can use that backup to restore a copy of your data warehouse to any region that supports Synapse Analytics.

And that’s it for disaster recovery.
