Overview of the VMware backup process
The following table describes the phases in the NetBackup backup process.
Table: NetBackup backup process
Phase | Description |
|---|---|
Phase 1 | The NetBackup primary server initiates the backup. |
Phase 2 | The NetBackup client on the VMware backup host initiates a VMware snapshot on the virtual machine. |
Phase 3 | 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 4 | The VMware server creates a snapshot on the virtual disk datastore. |
Phase 5 | The NetBackup client reads the snapshot from the datastores and writes the data to the NetBackup storage unit. |
