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.
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.
VMware LLC is an American cloud computing and virtualization technology company headquartered in Palo Alto, ... snapshots, encrypted virtual machines, and some ...
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 ...
Regular snapshots of the VM (its simulated hard disk storage, its memory, and its virtual peripherals) are taken in the background by the hypervisor, or by a set of administrative scripts. Each new snapshot adds a differential overlay file to the top of a stack that, as a whole, fully describes the machine. Only the topmost overlay can be ...
VM-aware storage has some similarities to and can benefit from software-defined networking, but is distinct in that the latter provides general purpose physical equipment that can be customized and configured in software whereas VM-aware storage is designed for virtual machines.
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.
