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.
A snapshot is a state of a virtual machine, and generally its storage devices, at an exact point in time. A snapshot enables the virtual machine's state at the time of the snapshot to be restored later, effectively undoing any changes that occurred afterwards.
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 ...
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.
VMware LLC is an American cloud computing and virtualization technology company headquartered in Palo Alto, California. [2] VMware was the first commercially successful company to virtualize the x86 architecture. [3] VMware's desktop software runs on Microsoft Windows, Linux, and macOS.
Building on the concept of VMware, esurfing cloud has launched a new software-defined storage product called HBlock. HBlock is a lightweight storage cluster controller that operates in user mode. It can be installed on any Linux operating system as a regular application without root access, and deployed alongside other applications on the server.
In May, 2017, Dell EMC announced ScaleIO.Next, featuring inline compression, thin provisioning and flash-based snapshots. The new release features enhanced snapshot tools and features and full support for VMware Virtual Volumes (VVols), as well as volume migration for deployments that want to take advantage of lower cost media for low-priority ...
