Here is a short information about the Option available in Netbackup for VMware.
VMware Credentials in Netbackup:
- Click Media and Device Management > Credentials > Virtual Machine Servers.
- Click Actions > New > New Virtual Machine Server.
- On the Add Virtual Machine Server dialog, enter the name of a virtual machine server (vCenter server or ESX server).
Note: The credentials for ESX or vSphere client are needed that Netbackup can create and access the virtual machine Snapshots.
VMware backup host
- Backup Media Server: This option allows a Windows media server that is selected in the policy to operate as the backup host. (Selection of the media server is determined by the specified storage unit.) To operate as the backup host, the Windows media server must contain NetBackup client software.
Note: The storage unit that is specified in the policy must be unique to your Windows media servers. If the storage unit is also available on a UNIX media server, the snapshot cannot succeed.
Note: When the Backup Media Server option is selected, NetBackup cannot determine a host to perform policy validation. To validate the policy, temporarily select one of the possible media servers as the backup host (do not select Backup Media Server). When the policy validates successfully, reset the backup host to Backup Media Server.
- backup_host_name: Select a particular backup host to perform the backup.
Note: The backup hosts (but not backup media servers) must be identified in the Administration Console as follows: Go to Host Properties > Master servers > double-click the master server > Master Server Properties > VMware Access Hosts.
Enable file recovery from VM backup
- Enable recovery of individual files.
- all the files inside the virtual machines can be restored in the virtual machine or 2 different location
- still the full VM can be restored to the ESX / vSphere server
Enable block-level incremental backup
- For block-level backups of the virtual machine. This option reduces the size of the backup image.
Exclude deleted blocks
- Reduces the size of the backup image by excluding any unused or deleted blocks within the file system on the virtual machine. This option supports the following file systems: Windows NTFS, and Linux ext2, ext3, and ext4.
- This option uses proprietary mapping technology to identify vacant sectors (allocated but empty) within the file system.
To back up a virtual machine that contains Veritas Storage Foundation Volume Manager volumes, disable this option. Also make sure that the Enable file recovery from VM backup option is disabled.
Exclude swapping and paging files
- Reduces the size of the backup image by excluding the data in the guest OS system paging file (Windows) or the swap file (Linux).
- Note: This option does not exclude the swapping and paging files from the backup: it only excludes the data in those files. If the files are restored, they are restored as empty files
Primary VM Identifier
- VM hostname: The network host name for the virtual machine. (This option is the default.) NetBackup obtains the host name by means of a reverse lookup on the virtual machine's IP address. If no host name can be found, the IP address is used as the host name.
- VMware display name: The name of the virtual machine as displayed in the VMware interface. A display name is assigned to the virtual machine when the virtual machine is created. When virtual machines are included in a NetBackup policy, restrictions apply to the characters that are allowed in the virtual machine display name. Note: The restrictions also apply to other vSphere objects, such as floppy image name, parallel port or serial port file name, and CD-ROM ISO name. Each display name must be unique in your VMware environment.
- VMware BIOS UUID: The ID assigned to the virtual machine when the virtual machine is created. This ID may or may not be unique, depending on whether the virtual machine has been duplicated. This option is included for compatibility with the existing policies that use the older VM UUID identifier.
- VM DNS Name: The VMware DNS Name of the virtual machine. In vSphere Client, this name appears on the virtual machine's Summary tab.
Note: This name may or may not be associated with the virtual machine's IP address. VMware Tools obtains this name from the host name that is configured in the virtual machine. For further information on this name, refer to the documentation for the guest operating system.
- VM instance UUID: The globally unique ID assigned to the virtual machine when the virtual machine is created. This ID uniquely identifies the virtual machine within a vCenter server. Even if the virtual machine has been duplicated (such as within a vCloud), only the original virtual machine retains this instance ID. (The virtual machine duplicates are assigned different instance UUIDs.) This option applies only to backup hosts (NetBackup clients) at 7.5 or later. If your backup host is 7.5 or later, this option is recommended instead of the VMware BIOS UUID option.
Note: VM instance UUIDs are not available for standalone ESX 3.5 or ESXi 3.5 servers or for servers that VirtualCenter 2.5 manages.
Orphaned Snapshot Handling
- Ignore: NetBackup ignores any existing virtual machine snapshots (including snapshots previously created by NetBackup) and proceeds with snapshot creation and the backup.
- Abort: If any snapshot exists on the virtual machine, NetBackup aborts the job for that virtual machine only.
- Remove NBU: If a virtual machine snapshot exists that a NetBackup backup previously created: NetBackup removes the old snapshot, creates an updated snapshot, and proceeds with the virtual machine backup. (This option is the default.)
Enable Exchange Recovery
- This option enables recovery of the Exchange databases or mailbox messages from the virtual machine backups. If this option is disabled, you can recover the entire virtual machine from the backup, but you cannot recover the databases or mailbox messages individually.
Enable SQL Server Recovery
- This option enables recovery of individual files from Microsoft SQL data in the virtual machine backup. If this option is disabled, you can recover the entire virtual machine from the backup, but you cannot recover the SQL files individually.
Enable SharePoint Recovery
- This option enables recovery of SharePoint objects from the virtual machine backup. If this option is disabled, you can recover the entire virtual machine from the backup, but you cannot recover the SharePoint objects individually.
For Exchange, SQL and Sharepoint Recovery are the following notes:
To use the Enable SharePoint Recovery option, note:
- The Enable file recovery from VM backup option must be enabled.
- The Enable block-level incremental backup option must be disabled.
- san: For unencrypted transfer over Fibre Channel (SAN) or iSCSI.
- hotadd: Lets you run the VMware backup host in a virtual machine. This feature requires ESX 3.5 Update2 or later.For instructions on this transport mode and on installing the backup host in a VMware virtual machine, refer to your VMware documentation.
- nbd: For unencrypted transfer over a local network that uses the Network Block Device (NBD) driver protocol. This mode of transfer is usually slower than Fibre Channel.
- nbdssl: For encrypted transfer (SSL) over a local network that uses the Network Block Device (NBD) driver protocol. This mode of transfer is usually slower than Fibre Channel.
- Move Up, Move Down: Use these buttons to change the order in which NetBackup tries each selected mode. Highlight a mode and click Move Up or Move Down.For example: assume that all four transport modes are selected, and the order is san, hotadd, nbd, and nbdssl. If one of the virtual disks cannot be accessed using san, the san transport mode is not used for any of the virtual machine's disks. NetBackup then tries to use the hotadd mode for all the disks. NetBackup continues to try each mode until it finds one that succeeds for all the disks.
