KVM - Advanced attributes

The following additional parameters are available for KVM backups. In most situations, the best settings are the defaults.

Table: KVM advanced attributes

Configuration parameter

Description

Virtual machine quiesce

This option is enabled by default. In the great majority of cases, you should accept the default.

I/O on the virtual machine is quiesced before NetBackup creates the snapshot. Without quiescing file activity, data consistency in the snapshot cannot be guaranteed. If not consistent, the backed-up data may be of little or no value.

If this option is disabled, the snapshot is created without quiescing I/O on the virtual machine. In this case, you must perform your own analysis for data consistency in the backup data.

Caution: Cohesity does not recommend that you disable quiesce. In most cases, this option should be enabled.

Note:

If the QEMU guest agent is not installed, the backup fails.

Perform snapshot without quiescing if quiesced snapshots fail

Select this option to automatically perform the snapshot with quiescing if any backups of quiesced snapshots fail.
