5 Ways VMware vSphere Improves Backup and Recovery
VMware's latest enterprise-level hypervisor product suite, vSphere, includes many new features and technological enhancements over its predecessor, VMware Infrastructure 3 (VI3). While there are several reasons to upgrade to vSphere, this white paper focuses on how VMware improved various storage technologies, how they relate to data backup and recovery, and how the new vStorage advanced programming interfaces (APIs) allow for better storage integration with third-party backup applications.
Of the many new storage-related technologies in vSphere, the following offer direct benefits to backup and recovery of virtual machines by improving backup speeds, reducing backup windows and reducing the amount of storage required for backups.
- Improved support for thin-provisioned virtual disk files,
- New vStorage APIs for third-party integration,
- Improved iSCSI Software Initiator, and
- Hot-add of virtual disk snapshot files.
