How are organizations leveraging replication for DR?
For those people who have tried to use tape and traditional methods of backup and have found that they’re simply not able to meet their RTOs, those companies have gone to replication for DR, especially for their critical applications. So basically they’re using synchronous or asynchronous replication so that they constantly have a copy of their data offsite. This way, they don’t have to do a restore when they’re in a DR situation. They simply have to switch whichever copy of the data that they are using. Can you discuss the pros and cons of synchronous replication vs. asynchronous replication? It’s not so much pros and cons as it is that each one is appropriate for a different application. Synchronous replication is meant to have the updated copy continuously, completely up to date. It doesn’t give the acknowledgement of the write to the application until that write has been copied over to the target site. So that’s going to make sure that the target system is always up to date with th
