VMware VMFS (Virtual Machine File System) is VMware, Inc.'s clustered file system used by the company's flagship server virtualization suite, vSphere. It was developed to store virtual machine disk images, including snapshots. Multiple servers can read/write the same filesystem simultaneously while individual virtual machine files are locked.
It uses storage system snapshots as a source for backups and recovery of VMware VMs with disks residing on storage volumes. [22] [23] Veeam Backup & Replication also have build in direct NFS agent which allows to access NetApp snapshots directly from NAS storage bypassing hosts for backup, restore & storage scan operations.
VMware Workstation Pro can save the state of a virtual machine (a "snapshot") at any instant. These snapshots can later be restored, effectively returning the virtual machine to the saved state, [ 7 ] as it was and free from any post-snapshot damage to the VM.
DPX can protect data to disk, tape or cloud. It is used for various recovery use cases including file, application, BMR, VM or DR. DPX can spin up VMs from backup images, recover physical servers, bring up applications online from snapshot based backups, it can be used to recover from Ransomware.
Live migration, also called migration, refers to the process of moving a running virtual machine (VM) or application between different physical machines without disconnecting the client or application. Memory, storage, and network connectivity of the virtual machine are transferred from the original guest machine to the destination.
It can run virtual machines created by other VMware products and by Microsoft Virtual PC. VMware Server can preserve and revert to a single snapshot copy of each separate virtual machine within the VMware Server environment. The software does not have a specific interface for cloning virtual machines, unlike VMware Workstation.
In the context of virtualization, where a guest simulation of an entire computer is actually merely a software virtual machine (VM) running on a host computer under a hypervisor, migration (also known as teleportation, [1] also known as live migration) is the process by which a running virtual machine is moved from one physical host to another, with little or no disruption in service.
VMware provides a semi-automated tool called VMware vCenter Converter for moving physical servers running Windows or Linux into virtual environments while they are powered on. VMware vCenter Converter replaces two older utilities: Importer (bundled with VMware Workstation) and P2V Assistant.
