Questions # 1:

A company using Dell Avamar has decided to virtualize their Microsoft Exchange environment using VMware guests instead of physical systems.

Which backup methodology must they use to perform hot backups and restores of their Microsoft Exchange environment?

Options:

VMware Consolidated

VMware Image Level with Change Block Tracking

VMware Image Level without Change Block Tracking

VMware Guest Level

Answer

Explanation

Explanation/Reference:

You must use the backup agents to backup Exchange and SQL. Databases on Image level backups will not be consistent.

To backup the environments, you would need to do a guest level backup. i.e. Install the avamar agent, and the exchange VSS plugin on the Exchange server, and the SQL plugin on the sql server.

If you want to backup the OS, ensure you create windows datasets to skip the database files on the server, otherwise you'll be backing up database files that look totally different each time (consuming huge amounts of space on the grid), that will be no good to you (they'll be inconsistent)!

Besides the above points, the Exchange VSS plugin has some fairly useful functionality, like being able to backup databases in parrallel, and being able to do granular level restores (i'm still trying to get this to work).

Well worth using.

By default, what percentage of file system storage space is reserved for operating systems and checkpoint overhead on an Dell Avamar server?

Options:

Answer

Explanation

Explanation/Reference:

The OS View is the total file system in the Avamar, while the gsan View is the total allocated to stripes. Gsan view is 65% of the Avamar server and it is used mainly for user data - this is the licensed capacity. Above that, 20% of the system file space is used for checkpoint overhead and the remaining 15% is for the operating system.
