An incremental backup, which is faster and requires less storage than a full backup, captures changes made since the previous backup. Disaster recovery (DR) strategies are essential to ensuring the integrity, availability, and reliability of data, particularly in the event of unexpected failures or errors.

Hence, the node would still be available for other operations. Cons of logical backups As it reads all data, it can be slow and will require disk reads too for databases that are larger than the RAM available for the WT cache—the WT cache pressure increases, which slows down the performance.

This operation is quite expensive but our database can run it in a few milliseconds or less, thanks to several optimizations that allow the node to execute most of them in memory with no or little access to mass storage. It will also allow us to redirect read/write traffic to the primary and read-only traffic to all secondaries.

As I have talked about before, one of the reasons why we built Amazon DynamoDB was that Amazon was pushing the limits of what was a leading commercial database at the time and we were unable to sustain the availability, scalability, and performance needs that our growing Amazon.com business demanded. The opposite is true.
