Agentless Backup for VMware
You can use DPX to protect VMware assets, such as virtual machines and specific files stored on these machines. For VMware users, data protection for virtual machines running on VMware ESXi servers is a critical component of any virtualization strategy, and it presents unique challenges compared to the protection of physical machines.
Typically, Agentless VMware Backup is a fast and reliable data protection method for VMware assets. Backup targets include Catalogic vStor Server, NetApp Storage Systems, or Catalogic DPX Open Storage Server (OSS) from which previous backups can be restored.
Advantages and Capabilities
Agentless VMware Backup provides robust protection in VMware environments. All backups are done through one or more proxy servers, that communicate with VMs through vSphere. Backup agents are not required on VMs or any VMware components, thus VM data protection is referred to as “agentless”.
Agentless VMware Backup provides significant advantages:
No Maintenance of Data Protection Software on VMs
Agentless backup eliminates the overhead of installing and maintaining a backup agent on each VM. Where there are hundreds or even thousands of VMs to protect, the savings in administrative costs can be substantial.
High-Performance Backups
The Catalogic DPX Agentless Backup for VMware combines several key technologies of Catalogic Software and VMware to provide high-performance, low-overhead backups:
VMware vStorage APIs for Data Protection (VADP) enables off-host backup of virtual machines through DPX proxy servers. This dramatically reduces overhead allowing for frequent backups without affecting VM users and critical applications.
DPX Virtualization proxy servers provide parallel load balancing for multiple VMs and associated virtual disks, promoting faster backups.
VMware Change Block Tracking is utilized to recognize and back up only changed blocks. This improves backup performance by minimizing CPU, reducing storage needs, and reducing network overhead.
Flexibility, Administrative Simplicity
No backup software to maintain on VMs.
Auto-discovery and protection of new and modified VMs.
Covers all VMs on all vSphere hosts.
Supports most operating systems running on VMs.
Optional automatic discontinuing of protection for deleted VMs.
VMs selectable for backup at vCenter, datacenter, ESX server, and VM levels.
Simplified, wizard-driven recovery.
Recovery of entire VM to original or alternative ESX server.
Recovery of individual VMDKs.
File recovery for all VMs, using LUN mapping plus file system copy.
Agentless VMware Backup also complements Block Data Protection with the following features:
