The correct answer is D. all of the mentioned.
Automatic failover is a process that automatically switches to a backup system when the primary system fails. This can help to reduce downtime and improve the availability of your data.
Taking backups on a faster device can also help to reduce recovery time. This is because the backup data will be available sooner, and you will be able to restore your systems more quickly.
Taking multiple backups, one in the same location and another at a different location, can provide an additional layer of protection. This is because if one location is lost or damaged, you will still have the backup data from the other location.
Overall, all of the mentioned options can be used for reducing recovery time. The best option for you will depend on your specific needs and requirements.
