![]() NAS: NAS (network attached storage) transport mode enables the virtual server agent (VSA) proxy computer to read data directly from the network file server (NFS), without going through an ESX host or transferring data over the local area network (LAN). Encryption should be used for sensitive information, even within a private network. NBD SSL: Similar to NBD mode, but data transfer between the proxy computer and the ESX server is encrypted. The local area network (LAN) can be the production network or a dedicated backup network. NBD: Data is transferred using the TCP/IP connection between the ESX server and the proxy computer. If the virtual machine and the proxy are not on the same host, all datastores must be shared between the hosts. The ESX host the proxy is running on must have access to all datastores for the virtual machine. In HotAdd mode, the data volumes containing the virtual machines to be backed up are automatically mounted to the proxy, so they can be accessed by the proxy as a local disk. Hot Add: The Virtual Server Agent is installed on a virtual machine residing on an ESX server. SAN transport mode cannot be used if the proxy computer is a virtual machine. The ESX host is contacted only to coordinate access to the LUN. Data is read directly from the storage where virtual machines reside, without going through the ESX host or transferring data over the local area network (LAN). The Virtual Server Agent must have access to the datastore LUNs (logical drives) that provide storage for virtual machine disks. SAN: For directly connected storage using Fibre Channel (FC) or Internet SCCI (iSCSI) protocols. If the datastore is accessible to the ESX server for a virtual proxy, HotAdd is used. If the datastore is accessible to a physical proxy, SAN is used. Transport mode for VMware: Select one of the following options:Īuto: The transport mode is selected automatically based on the backup environment: To specify credentials for guest VMs in the VM group, click the key button ( ), and then provide the guest credentials.įile system and application consistent: Quiesces the file system and applications while performing the backup.Ĭrash-consistent: Takes a point-in-time snapshot of virtual machine data without quiescing. Virtual machine backup type: Select the type of backup to perform:Īpplication Aware: Uses in-guest application plug-ins to assist the Virtual Server Agent in quiescing the file system and applications and supporting granular application data recovery. of readers: Set the number of readers to control how many parallel read operations can be launched during backups. To edit other settings, in the Settings area, click Edit. To enable file indexing, move the File indexing for advanced reporting and search toggle key to the right. To discover VM owners during backups, move the Auto detect VM owner toggle switch to the right. For virtual machines where there is a known issue with CBT, you can turn off CBT to run backups using the cyclic redundancy check (CRC) method instead. With CBT, backups only write blocks that have changed since the previous backup. To use changed block tracking (CBT) for backups, move the Use changed block tracking toggle key to the right. In the Settings area, you can make the following changes directly: To modify the security associations for the VM group, in the Security area, click Edit. The VM groups area displays summary information for any existing VM groups. On the Hypervisors tab, click the hypervisor. ![]() Procedureįrom the navigation pane, go to Protect > Virtualization. If you enable file indexing, and the access node (VSA proxy) that is assigned to back up the VM group does not have the software packages that are required for file indexing, then Commvault installs those packages automatically. If you enable file indexing, and the MediaAgent associated with the backup plan or storage policy that is assigned to back up the VM group does not have the software packages that are required for file indexing, then Commvault installs those packages automatically.
