Removing backup preferences for a virtual machine

By removing backup preferences for a virtual machine, you can ensure that the plug-in automatically applies the server preferences to the individual virtual machine. If you enable or disable quiescing at the server level, the same setting is applied to the virtual machine for which the configuration has been removed.

1
Start the Backup Job Wizard, and click Create New next to the Selections list.
4
Click the virtual machine, and select Remove Backup Preferences from the context menu.

Unlocking a virtual machine

You can use the following procedure to unlock a virtual machine from the WebUI.

1
Start the Backup Job Wizard, and click Create New next to the Selections list.
4
Click the applicable virtual machine, and select Unlock Virtual Machine from the context menu.

 

Defining a backup strategy

About backup methods and types

The Plug‑in for VMware supports image-level and file-level backup methods:

Image-level backups use the VMware snapshot technology to provide point-in-time image of virtual machines. You can use these backups to perform the following types of recoveries:

Image-level backups are supported on Linux- and Windows-based virtual machines. These backups can be performed with or without CBT.

When CBT is enabled on a virtual machine, the following backup types are supported:

Full Backup: A Full Backup provides a backup of all allocated sectors on a virtual drive. Full Backups take longer to complete and consume more backup media. These backups serve as the base backup for future Incremental and Differential image-level backups.
Differential Backup: A Differential Backup provides a backup of disk sectors that have changed since the last Full Backup. Differential Backups speed up recovery since the plug-in is only required to restore two savesets.
Incremental Backup: An Incremental Backup provides a backup of disk sectors that have changed since the last Full, Differential, or Incremental Backup. Incremental Backups consume minimum storage space and are quicker to perform. However, data recovery can take more time depending on the number of savesets that the plug-in is required to restore.

Only Full image-level backups are supported on virtual machines that do not use CBT.

The file-level backup method is only available to Windows-based virtual machines. File-level backups allow you to restore a single file or a set of files. You can use these backups to recover from data loss due to user errors, data corruption, or accidental deletion of files.

NOTE: Only the Windows version of the Plug‑in for VMware supports file-level backups of virtual machines.

The plug-in can only mount a virtual machine that uses the same version, or an earlier version, of the OS used by the backup proxy. For example, the plug-in cannot mount a Windows Server 2016 virtual machine that is located on a Windows Server 2012 backup proxy.

The Plug‑in for VMware uses NetVault Backup Plug-in for FileSystem (Plug-in for FileSystem) for file-level backups.

The Plug‑in for VMware supports the following types of file-level backups:

Full Backup: A Full Backup provides a backup of all selected files and folders. Full Backups take longer to complete and consume more backup media. However, restores are faster since the plug-in is only required to restore a single saveset. Full Backups serve as the base backups for subsequent Incremental and Differential Backups
Differential Backup: A Differential Backup provides a backup of files that are new or have changed since the last Full Backup. Differential Backups speed up recovery since the plug-in is only required to restore two savesets. However, these backups consume more storage space and take more time to complete than the Incremental Backups. Differential Backups duplicate the data backed up by previous backups of the same type.
Incremental Backup: An Incremental Backup provides a backup of files that are new or have changed since the last Full or Incremental Backup. Incremental Backups consume minimum storage space and are quicker to perform. However, data recovery can take more time depending on the number of savesets that the plug-in is required to restore.
