VMware ESXi is a “bare metal” hypervisor which does not run in an external operating system, but is incorporated in the core of it. For its execution it relies on a Linux system prepared to execute the processes of the hypervisor and VMware virtualization components. Until version 3.5u4 its executable base code was in 32 bits, from version 4 (vSphere) it became 64 bits, so its requirements are higher but its performance is higher with more efficient, robust and reliable.
Bacula Systems’ VMware backup solution is used to perform VMware ESXi backups and especially fast data recovery of your VMware ESXi hosts using vSphere with Bacula Enterprise Edition. Our VMware backup software also provides fast ESXi virtual machine bare metal recovery and especially quick Single File Restore which is reducing the time of re-installation and recovery of the virtualization host in case of any failure.This VMware backup software also enables users to backup VMware ESXi at guest level. The Bacula’s VMware backup solution can work either over a SAN or via Network Block Device. Our VMware backup tool integrates VMware’s Changed Block Tracking (CBT) technology to ensure that only the blocks that were modified since the initial Full, or the previous Differential or Incremental backup are relayed to the current Differential or Incremental vSphere backup stream, providing markedly more efficient ESXi backups, lighter network load and optimization of the disk space. Using our VMware ESXi backup software together with Progressive Virtual Full dramatically reduces disk storage utilization and lowers the I/O operations as well.
This Single File Restore capability for VMware backup solution comes with industry-leading speed and convenience. Finding and restoring single files is now so fast and easy, you need to see it to believe it. This is done from any of the management consoles with a few clicks in the web environment or GUI by indicating some criteria or parameters from CLI.
Our VMware backup tool is available for the following platforms:
Our VMware backup solution is compatible with Bacula Enterprise 6.x and higher. Backup VMware ESX or ESXi versions 4.0, 4.1, 5.1, 5.0, 5.5 and 6.0 and 6.5 with the vStorage API enabled.
Our VMware backup software can store ESXi VM backups to:
Single File Restore for VMware VM backup software becomes particularly useful when you need to restore from a backup of VMware virtual machine a critical data file that has become corrupted or lost for some reason. Want to avoid restoring from the backup of the entire VMware virtual machine? Frequently, recovery cases only require single files to be restored from a backup of VMware VM. In these cases, you can now save yourself a lot of effort and time – and just recover the individual files that you need from vSphere VM backups.
Bacula Enterprise performs the check of VMware backup and recovery operations. This is done during the execution phase or by configuring and running verification jobs that allow these checks to be carried out.
What are the advantages obtained with the verification of VMware backups? Although there are multiple advantages, the main one is to validate the consistency of the backed up data since it can be affected by various factors that decrease its usefulness such as physical disk errors, logical software errors or changes in the permissions of the objects.
