This segment presents important timelines in site recovery and auto-reseed, including best practices regarding the database volume to expidite recovery.
- [Instructor] For the last two chapters…we've covered the features of database availability groups…for high availability and for site resilience.…I wanna wrap up these two chapters with some…realistic expectations of these features.…The concept of high availability usually requires…more than one site because it's not uncommon for…an issue like a power outage to take down an entire site.…For that reason, DAGs should include servers…at multiple locations,…but sometimes the problem is a little more localized…as we just mentioned a defective hard drive.…
In this situation, it's preferred to have at least…one more Exchange server from the DAG in the same…active directory site.…But if you are able to create a DAG of four or more members…across two sites, losing a server for a few hours…or even a couple days is not a catastrophe.…With that in mind, Microsoft designed the site resilience…options of database availability groups to not be so hasty…to rebuild a lost a database that it might cause…other problems elsewhere.…
