DatabaseandApplicationProtection

1. Do I still need to use separate Backup Exec Database or Application Agents for

backups?

Answer-

Yes, it is extremely important that Backup Exec Database or Application Agents continue to

be installed inside of Guest virtual machines and separate regular database or application

level backups be performed of virtualized applications such as Microsoft SQL, Exchange,

SharePoint, Oracle, Active Directory, Lotus Domino, etc. These applications and databases

require regular log truncation, database maintenance, consistency checks, etc that are

performed only as part of a regular Backup Exec database or application Agent-level

backup. If these separate Database Agent-level backups are not performed regularly,

application log files could continue to accumulate, eventually fill the entire disk, and cause

application or database failure.

Additionally, Backup Exec 12.5 database and application Agent backups allow granular

recovery and point-in-time recovery of the application itself. For example, to recover an

individual Microsoft Exchange mailbox, message, contact, calendar item, or database, the

backup must have been performed separately with the Backup Exec Agent for Microsoft

Exchange.

2. How do I protect and recover entire Guest virtual machines that run applications

or databases like Microsoft SQL, Exchange, SharePoint, etc?

Answer-

Applications that utilize the Microsoft Volume Shadow Copy Service (VSS) framework on

Windows 2003 and 2008 can be protected as part of an image-level backup of the entire

Guest virtual machine with AVVI using a “VSS Requestor/Provider” that must be installed

inside of the Guest virtual machine running the application.

There are two options for obtaining a VSS “Requestor/Provider” for your Windows Guest

virtual machines running Windows 2003 or later:

• A generic version can be obtained as part of ESX 3.5 Update 2 from VMware

• A BackupExec specific version can be obtained as part of Backup Exec 12.5

AVVI on the Backup Exec 12.5 CD. Please see your Backup Exec 12.5

Administrator’s Guide for more details on how to install the VSS

“Requestor/Provider”

• Each VSS Requestor/Provider should be installed separately and never on the

same system at the same time. Please select one or the other.

If your application is not “VSS aware”, this information does not apply. Check with your

application or database vendor to confirm its VSS capabilities.

3. How are applications that are not

VSS-compliant protected?
