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.
Snapshots have also been available in the NSS (Novell Storage Services) file system on NetWare since version 4.11, and more recently on Linux platforms in the Open Enterprise Server product. EMC's Isilon OneFS clustered storage platform implements a single scalable file system that supports read-only snapshots at the file or directory level.
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.
Operating-system-level virtualization, also known as containerization, refers to an operating system feature in which the kernel allows the existence of multiple isolated user-space instances. The usual goal of virtualization is to centralize administrative tasks while improving scalability and overall hardware-resource utilization.
Since a snapshot is a subvolume, creating nested snapshots is also possible. Taking snapshots of a subvolume is not a recursive process; thus, if a snapshot of a subvolume is created, every subvolume or snapshot that the subvolume already contains is mapped to an empty directory of the same name inside the snapshot.

After the Easy Install operation is complete, VMware Tools may fail to install as some guest operating systems, such as Windows 7, Server 2008 R2 and Server 2012 R2, need some Windows Updates to first be installed (KB4474419 and KB4490628 for Windows 7 and Server 2008 R2; KB2919355 and installation of the .NET Framework 3.5 for Server 2012 R2)
VMware ESXi, its enterprise software hypervisor, is an operating system [4] that runs on server hardware. [ 5 ] On November 22, 2023, Broadcom Inc. acquired VMware in a cash-and-stock transaction valued at US$ 69 billion, [ 6 ] with the End-User Computing (EUC) division of VMware then sold to KKR and rebranded to Omnissa.
