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.
Thus, the entire stack of snapshots is virtually a single coherent disk; in that sense, creating snapshots works similarly to the incremental backup technique. [citation needed] Other components of a virtual machine can also be included in a snapshot, such as the contents of its random-access memory (RAM), BIOS settings, or its configuration ...
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.
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.
To avoid downtime, high-availability systems may instead perform the backup on a snapshot—a read-only copy of the data set frozen at a point in time—and allow applications to continue writing to their data. Most snapshot implementations are efficient and can create snapshots in O(1). In other words, the time and I/O needed to create the ...

At this point the snapshot can be backed up through normal methods. [50] A snapshot is an instantaneous function of some filesystems that presents a copy of the filesystem as if it were frozen at a specific point in time, often by a copy-on-write mechanism. Snapshotting a file while it is being changed results in a corrupted file that is unusable.
VMware Player was available for personal non-commercial use, [5] or for distribution or other use by written agreement. [6] VMware, Inc. did not formally support Player, but there was an active community website for discussing and resolving issues, [7] and a knowledge base. [8]
