The backup Job above named “HyperV-job” was executed and finished successfully. With that being said – if your Hyper-V data is spread across several drive letters you will need either a dummy text file on each of them (unless you also do additional file backups on that Windows Server anyway), or you will need to make use of the Alldrives Plugin that comes with the Bacula Enterprise client for Windows. Please note that the FileSet contains a reference to a dummy text file that is necessary because the VSS snapshot of a Microsoft NTFS filesystem is triggered only if at least one file is specified. The plugin line in the fileset tells Bacula to back up all virtual machines found on this hypervisor. This is everything you need to get started. Please find an example configuration below: On your Bacula Director you will have to add a Client resource for the Hyper-V host (in our case a Windows Server 2012R2 with Hyper-V activated), and a FileSet resource (if not previously created for a different backup client in Bacula all resources can be reused) and finally a Job resource that defines all parameters of the backup job (when it is scheduled with which level for which fileset, etc.). How-to backup a Hyper-V host with Bacula Enterprise Edition We will configure Hyper-V backup as an example for backup of virtual machine with Bacula Enterprise. No matter which hypervisor you use, the process that follows in this how-to is always similar. Where possible, such as with VMWare, image based backups allow for incremental backups and single file restores as well using tools like Changed Block Tracking (CBT) and the single file restore capabilities presented by VMWare’s backup API.īacula Enterprise’s virtual machine backup plugins are all configured in a similar way. Bacula Enterprise – Supported Virtualization Enginesīacula Enterprise has plugins to natively integrate with and backup more virtual machine-types than any other backup vendor:ĭepending on the tools available from the hypervisor, the backup is either snapshot based or file based. Bacula Systems support can help determine which is the best approach for a given environment. However, it may be preferable to install a backup client and database-aware backup software on these machines for more granular backups of important databases and applications. In many cases, the virtualization software is able to quiesce the filesystem through the use of guest tools, and this often means that databases can be reliably backed up with a hypervisor initiated backup. There are some potential pitfalls to look out for, such as backing up databases running on a virtual machine. Single file restore is available as long as the hypervisor API allows us to access them, so there is no loss of functionality over file backups.New clients are automatically detected and added to the backup, reducing the risk of a machine being ‘missed’.There is no need to install the Bacula client component (FileDaemon) on each virtual machine individually.The hypervisor is a convenient central place to orchestrate all backup operations for your virtual environment.Some of the major advantages of performing backups at the hypervisor for virtual machines include: This how-to will cover some of the advantages of adding hypervisor-level backup of virtual machines to your Bacula Enterprise installation, and demonstrate the basics of setting up these backups for a HyperV environment. And of course, by using Bacula, the backed up data and applications benefit from the especially high levels of security that Bacula offers over other backup software vendors. Performing backups at this level rather than at the more ubiquitous file level provides many advantages, though in many cases a combined approach that uses both file and hypervisor backups will provide the best coverage in complex environments with virtual machines.
