■ Performs full backups and incremental backups, including block-level
incrementals.
■ Backs up the full virtual machine.
■ Backs up the virtual machines even when they are turned off.
■ Can restore selected files from the backup.
Overview of the VMware backup process
The following table describes the phases in the NetBackup backup process.
Table 3-1
NetBackup backup process
DescriptionPhase
The NetBackup master server initiates the backup.Phase 1
The NetBackup client on the VMware backup host initiates a VMware
snapshot on the virtual machine.
Phase 2
Windows: VSS synchronizes the file system on the virtual machine.
Linux: If snapshot quiesce is enabled in the Linux guest OS, the file system
is synchronized on the virtual machine. (Contact your operating system
vendor and VMware for additional information on how to enable snapshot
quiesce.)
Phase 3
The VMware server creates a snapshot on the virtual disk datastore.Phase 4
The NetBackup client reads the snapshot from the datastores and writes
the data to the NetBackup storage unit.
Phase 5
Transport modes options (VMware)
The transport modes determine how the snapshot data travels from the VMware
datastore to the VMware backup host. The appropriate mode depends in part on
the type of network that connects the VMware datastore to the VMware backup
host.
By default, all modes are selected. NetBackup tries each transport mode in order,
from top to bottom. It uses the first mode that succeeds for all disks in the virtual
machine.
