Configuring SAN-based backups with Backup Exec 2010 Agent for VMware Virtual Infrastructure
is relatively simple after following some basic guidelines:

• For performance reasons, it is recommended that only one Backup Exec server be zoned
to see a set of VMFS LUN’s at one time.

• Zone the LUN’s containing the VMFS datastore so that the Backup Exec 2010 server can
see and access them.

• On the Backup Exec 2010 server, ensure that the “automount disable” and
“automount scrub” commands have been run to disable automatic drive letter
assignment.

• As a result of the “automount disable” and “automount” scrub” commands having been
run, the VMFS datastore LUN’s should appear in Windows Disk Administrator as
“unknown”. Do not attempt to mount, partition, or format these disks.
