A customer is planning to use EMC NetWorker integrated with Data Domain to backup their enterprise. Data Domain will be used to replicate backups to an offsite location to satisfy regulatory requirements. The customer is concerned about the difficulty in managing their backups and backup clones with two interfaces.
What could be done to simplify the management of backups and clones?
A customer has a large backup environment using EMC NetWorker integrated with Data Domain. They have a requirement to backup their hosts every night. They start all of their host backups at the same time. Each night during backups, their network utilization is high and the backups take a long time.
What is a recommendation to reduce the network utilization and backup time while minimizing cost?
While installing an EMC Avamar deduplication node in a NetWorker backup solution, the Microsoft Windows client backup jobs fail to run. Which process should be running on the client during the backup?
A company just converted its physical server environment to a virtual environment using vSphere 5. They have asked you to assist with creating a backup strategy for their virtual machines. The company wants to perform file level backups of their virtual machines without installing backup agents on them.
Which vSphere feature will provide this capability?
Scenario 1
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.
Refer to Scenario 1.
What must be done to ensure the transaction logs and any changed database files are backed up during an incremental backup of each database instance on the server?
