Host-Based Backup Challenges in Virtualized Environments.


Posted by Dave Mathson - 24 August, 2021

Virtualization allows you to not only increase utilization and reduce the number of servers, but also move virtual machines (VMs) between servers, accelerate system provisioning and deployment, and reduce hardware and energy costs. However, virtualization creates new backup challenges.

Legacy backup solutions were designed for physical server infrastructure with one application per server. These solutions don’t effectively support VMs, so administrators would typically install agents on every VM. This approach was inefficient and only got worse as the number of VMs increased and data volume skyrocketed. Because VMs share servers, a high number of simultaneous VM backups would also drain server resources and create performance issues.

Host-based backup overcomes many of the shortcomings of installing an agent for every VM. However, host-based backups require all VMs to run a supported operating system and all applications must be compatible with the backup application. Also, because VMs move between servers, a host-based backup could include different sets of VMs than the previous backup.

The backup problems with virtualization are exacerbated by the fact that many organizations are slow to upgrade their backup platforms. That means the solutions in place are using older technologies that can’t meet the performance requirements of newer business applications. Organizations usually don’t realize problems with their legacy backup exist until performance starts to go south.

There are two options for VM backup. The first is to upgrade to newer backup software that’s capable of supporting host-based VM backup. However, this approach doesn’t eliminate potential issues with application compatibility and VM mobility. The second option is to switch to a VM-specific backup solution for virtualized servers while the legacy solution takes care of all your servers.

Veeam Backup and Replication version 11.0 is capable of backing up virtual, physical and cloud workloads through a single management console. You can eliminate your legacy backup system and combine VM backup and replication into a unified software solution. Create image-level VM backups with advanced, application-aware processing, using storage snapshots from the world’s leading storage providers. Veeam SureBackup then automatically tests and verifies every backup and VM for recoverability.

Veeam’s Scale-out Backup Repository allows you to create a single virtual pool of backup storage and easily increase capacity when needed. Instead of building and maintaining infrastructure in a remote facility, use Veeam Cloud Connect for fast, secure cloud backup. Built-in WAN acceleration saves bandwidth and takes backups offsite up to 50 times faster.

Veeam Backup Solution and Replication can be integrated directly with HPE primary and secondary storage through StoreVirtual and StoreOnce. This allows you to minimize data loss and downtime by taking more frequent storage snapshots and implementing a more cohesive backup and disaster recovery strategy. Combining Veeam to backup servers with HPE makes it possible to achieve recovery time and point objectives of less than 15 minutes for all applications and data.

As your data center environment becomes more virtualized, the limitations of your legacy backup solutions will become painfully obvious, if they haven’t already. Let us show you how Veeam Backup and Replication coupled with HPE storage enables you to centrally manage backup for all workloads and ensure application performance.
