www.it-ebooks.info Chapter The same set of tests and verification processes are performed for replicas as well; when replicas are involved, the process is called SureReplica, but in essence, this is the same thing SureBackup requires Veeam Backup & Replication Enterprise or higher licenses Universal Application-Item Recovery (U-AIR) Universal Application-Item Recovery (U-AIR) is one of the most useful advanced features in Veeam Backup & Replication It allows for single item restore for several applications, such as Microsoft Active Directory, Microsoft SQL Server, and Microsoft Exchange In addition to this, it also lets the administrator restore single files from both Microsoft Windows and Linux-based VMs as shown in Chapter 3, Restoring Data In order to use application-item recovery, there needs to be a corresponding SureBackup job as this is the basis for the virtual lab environment that is created on demand To be able to restore single application items such as user accounts or groups from Microsoft Active Directory, all the dependencies need to be put into an application group to ensure that the virtual lab that is created for restore purposes is a copy of the production environment In the case of Microsoft Exchange, this application group needs to contain an Active Directory domain controller, a DNS server, and the Exchange server itself to be functional Usually such a restore process is started by the application owner, or administrator, who installs the required U-AIR wizard to his/her own workstation and uses it to submit a request for a virtual lab Once the Veeam Backup & Replication administrator approves it for a given time period, the virtual lab is fired up and the administrator who requested access is notified that the environment is ready The application-item recovery is then started and performed using the U-AIR wizard installation on the local workstation It utilizes a proxy VM that Veeam Backup & Replication manages to ensure availability between both the production environment (restore target) and the lab environment (restore source) Once finished, the lab can be shut down, or it will be automatically shut down when the time granted for the lab has expired [ 85 ] www.it-ebooks.info Other Features Quick Migration Quick Migration is a feature that is really helpful when you want to move VMs from one host to another and VMware vMotion or Storage vMotion isn't available Perhaps you have several standalone ESXi hosts running without vCenter and there is a need to move VMs from one host to another The Quick Migration feature of Veeam Backup & Replication is available in the free edition, as well as in the paid editions, and could be really helpful for those one-off migration scenarios This will require the ESXi hosts to be licensed at Essentials or higher (though the communication can go directly to the ESXi hosts if the vCenter Server application is not used) and can migrate VMs from one host to another or from one datastore to another, or both Quick Migration does a series of API calls to the ESXi host or vCenter Server that includes rebuilding the VM on the target storage This migrates the datastore swap file and the active host memory depending on the migration scenario Just install a copy of the free version of Veeam Backup & Replication on a physical server or VM, add the source and target ESXi hosts to the Veeam Backup console, you can then start moving those VMs around without the need for shared storage or licensed ESXi hosts All you need is a basic Veeam Backup & Replication infrastructure in place In fact, since Quick Migration works regardless of the VM state, you can even live migrations of powered-on VMs from one host to another As long as there is basic network connectivity between the target and source hosts, all that is required is a simple right-click on one VM, or several, in the inventory and selecting Quick Migration When Quick Migration is started, the following steps are performed by Veeam Backup & Replication: The VM configuration file is copied from the source host to the destination host A snapshot is created and the VMs disk content is copied to the new destination The VM state and changes made after the snapshot creation are moved to the new location If there are compatible CPUs on the source and destination hosts, a Veeam technology feature called SmartSwitch is used to suspend the VM on the source and resume it on the destination host without any interruption In case there are non-compatible CPUs, the VM is stopped to transfer the changes made after snapshot creation before it is powered up again on the destination host [ 86 ] www.it-ebooks.info Chapter SAN Support Veeam and Hewlett-Packard have worked together to integrate SAN snapshot support directly into Veeam Backup & Replication If you have a supported HP SAN available in your infrastructure, you can use their native snapshot functionality to perform backups This places a lot less load on your infrastructure, and the time a VM snapshot has to exist is significantly lowered, ultimately speeding up the backup process At the moment, the following are supported: • HP StoreServ (3PAR) • HP StoreVirtual (LeftHand/P4000 series) • HP StoreVirtual VSA (Virtual Storage Appliance) Veeam Backup & Replication v8 will introduce functionality for NetApp systems To be able to use SAN support features, the storage array needs to be added to the Veeam Backup & Replication infrastructure Once that is done, backup jobs can be configured to utilize the native snapshot functionality This enables frequent snapshots of IO-intensive applications, without significant impact on the infrastructure By creating a SAN snapshot immediately after the VM snapshot has been created, the VM state is captured without copying any data The SAN snapshot is then mounted on the backup proxy, and data is copied without impact on the original VM This also means that the SAN snapshot itself is no longer needed after the backup job has finished, eliminating the need for long-term storage of SAN snapshots This feature also works with Changed Block Tracking and the other advanced features Veeam Backup & Replication offers such as copy jobs In addition to utilizing SAN snapshots for backup purposes, Veeam Explorer for SAN Snapshots allows an administrator to view and manage SAN-level snapshots It allows you to mount snapshots directly to the ESXi hosts, promoting it as a new LUN to selected ESXi hosts Veeam Explorer for Storage Snapshots is included in Veeam Backup & Replication Free Edition, while the backup from SAN snapshot feature is available in the Enterprise Plus license tier [ 87 ] www.it-ebooks.info Other Features vCloud Director support From the administrator's perspective, working with vCloud Director vApps is very similar to working with traditional VMs in a VMware vSphere environment Once the vCloud Director infrastructure is added to Veeam Backup & Replication, it's content is available for protection The following items are available for selection: • vApp • Organization vDC • Organization • vCloud Director instance As with regular backup jobs, these backups can be scheduled and performed automatically Restore of vCloud Director-based backups are also performed in the same familiar manner as with vSphere-based VMs, and features such as Instant VM Recovery are also available It is even possible to restore an entire vCloud Director-based VM to a vSphere infrastructure directly from the restore wizard To be able to protect a vCloud Director environment, the Enterprise license or higher, is required Veeam® Backup Enterprise Manager Enterprise Manager is an optional component that is installed on the Microsoft Windows server in the environment This can be either a physical server or a virtual one, and the Enterprise Manager component can be installed on a Veeam backup server or as a dedicated server When an Enterprise Manager is installed, it acts as a federated view for all connected Veeam backup servers, centralizing the management of jobs and reporting It also enables the indexing of files inside Microsoft Windows guest OS backups, making it possible to search for files in all current and archived backups regardless of media type and location The license level governs how much data Enterprise Manager retains If you have the Standard license, Enterprise Manager will only keep an index of those backups that are currently stored in backup repositories If Enterprise or Enterprise Plus licenses are in use, it will also keep track of files on an archived medium, such as tape Enterprise Manager uses its own SQL database; it does not share a database with the backup server [ 88 ] www.it-ebooks.info Chapter Once installed, the Enterprise Manager is reached by opening its web-based administration interface This is available, by default, at https://host-name:9443 Log on using a user account that is a member of the local administrator group You can then add all your Veeam backup servers to the Enterprise Manager, after which it will, by default, query them every 15 minutes for any changes and job status Enterprise Manager also acts as a central licensing repository where you can manage the licenses for your entire Veeam Backup & Replication infrastructure Enterprise Manager also offers extensive granularity You can add other users or user groups and give them specific role-based access You can, for instance, create a scheme where some users have access to restore some VMs but not all of them This can be particularly useful in larger environments, where you want to give application owners restore access on their own applications but not other parts of the infrastructure This kind of self-service recovery can greatly reduce the amount of calls to the backup administrator and helps application owners get their applications up and running again quickly in case of a disaster The granular permissions also lets backup administrators safely delegate file-restore operations without the need to provide general access to all of the backed up data [ 89 ] www.it-ebooks.info Other Features Veeam® Backup Search If the backup jobs defined on the backup servers have the guest file indexing option checked, the files get indexed and they will be available through the search interface in Enterprise Manager For large environments, it is possible to install the search component on a dedicated Microsoft Search Server to offload the Enterprise Manager For smaller environments, the Enterprise Manager server can process indexing on its own, without the need for a Search Server installation 1-Click VM Restore 1-Click VM Restore is available in Enterprise or Enterprise Plus licensed environments and enables the restoration of a VM with a single click in the Enterprise Manager interface Given that the user performing the operation has sufficient permissions, this allows for very quick restoration of a VM to its original location All the user has to is to find the VM, select an available restore point, and select restore Users can perform this operation without having to log in to the Veeam Backup & Replication server or have any software installed locally on their workstation Everything is controlled via the web interface of Enterprise Manager [ 90 ] www.it-ebooks.info Chapter vSphere Web Client plugin While the Enterprise Manager offers a web interface, it also offers the possibility to show details of Veeam Backup & Replication statuses via the VMware vSphere Web Client This means that vSphere administrators can view details of statuses directly from their own day-to-day management interface As long as a loggedin user in vSphere Web Client has appropriate permissions in Veeam Enterprise Manager, they can view the job status for their VMs as well as information on both used and available backup storage space, and statistics for processed VMs The Web Client plugin is installed from the Veeam Enterprise Manager interface by adding a vCenter instance to it In order for the plugin to work, the vSphere Web Client must be vCenter Server 5.1.0a (build 880146) or newer, and the Single Sign-On service must be running After installation, a new Veeam Backup & Replication option is presented in the left-hand side navigation pane of the vSphere Web Client [ 91 ] www.it-ebooks.info Other Features Summary This chapter covered some of the features available in Veeam Backup & Replication that were not detailed in the previous chapters Veeam Backup & Replication offers a rich set of options and capabilities, enabling it to grow at the same rate as your infrastructure Advanced features such as SureBackup, SureReplica, Universal Application-Item Recovery, Enterprise Manager, and the vSphere Web Client plugin give even more value to the backup solution, in addition to the basic backup and replication
