You have a customer with a large IBM Lotus Domino environment. The customer is in the process of migrating from a UNIX to a Microsoft Windows infrastructure. As part of this process, they are going to perform a refresh of the hardware and software that Domino is running on. In addition, they will migrate all client backups to a new EMC NetWorker environment. The new backup environment consists of a

NetWorker server and two storage nodes running on Windows 2008.

The Domino environment consists of a single server running two instances of Domino. The total amount of data that needs to be backed up is approximately 900 GB. The Domino server will have connections to both the SAN and the LAN. They would like to perform hot backups of the databases using the NMDA but are leaving specific design decisions to you.

Additionally, the customer would like to send all data to disk for onsite backups and clone the first full backup of the year to tape for long-term offsite retention. The backup target infrastructure consists of a single Quantum i2000 tape library with six LTO-4 tape drives in addition to two EMC Data Domain 890s. One Data Domain will be located at their primary site. The second Data Domain is at the disaster recovery (DR) site as a replication target for the first.

One of the customer's major concerns is the backup speed of the Domino environment. They are interested in any best practices they can implement to improve backup performance at the Domino level.

Furthermore, they are looking for guidance in using NMDA to backup the data and leverage their backup infrastructure in the most efficient way.

To achieve optimal backup performance, which recommendation would you make regarding the disk layout of their Domino server?

A. Install the operating system, Domino data, and the transaction logs on separate drives B. Install the operating system on the C:\ drive and Lotus Domino on the D:\ drive

C. Install Lotus Domino on the C:\ drive with the operating system but keep the transaction logs on the D:\ drive

D. Install the operating system, Domino data, and the transaction logs on the same fast SAN disk Correct Answer: A
