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