At the end of this video, the student will learn how to set up and utilize a lagged copy of Exchange 2016 databases. A lagged copy allows you to utilize database availability groups to create a copy that is purposefully behind the other databases in case of system-wide corruption. This can assist getting email back up and running more quickly in case of disaster or virus outbreak.
- [Instructor] The purpose of the lagged database copy…is to provide a recovery mechanism for the…rare event of system-wide or catastrophic corruption.…It's not intended for individual mailbox recovery…or individual item recovery.…By utilizing the lagged database copy in this manner,…it's important that we understand that…the lagged database copy is not a…guaranteed point in time backup.…The lagged database copy will have an availability threshold…due to periods where the disk containing the lagged copy…is due to disk failure.…
For example, if we have a lagged copy of one hour…between the highest activation number,…in this case number two, and the active database,…number one, then if number one's database becomes corrupt…and we activate the database on number two,…then we'll lose one hour of email, but we'll still have…the rest of the email available.…Although it's not designed as a type of backup,…it certainly can be used as a type of backup,…since it does get data to you…that is mostly complete.…
If you choose to have a lagged copy that is farther…
