VM-aware storage (VAS) is computer data storage designed specifically for managing storage for virtual machines (VMs) within a data center. The goal is to provide storage that is simpler to use with functionality better suited for VMs compared with general-purpose storage.
Traditional backups only restore data from the time the backup was made. True continuous data protection, in contrast to "snapshots", has no backup schedules. [5] When data is written to disk, it is also asynchronously written to a second location, either another computer over the network [6] or an appliance. [7]
Shadow Copy (also known as Volume Snapshot Service, [1] Volume Shadow Copy Service [2] or VSS [2]) is a technology included in Microsoft Windows that can create backup copies or snapshots of computer files or volumes, even when they are in use. It is implemented as a Windows service called the Volume Shadow Copy service.

Veeam backup server – a Windows-based physical or virtual machine where Veeam Backup & Replication is installed. It is the core component responsible for all types of administrative activities in a backup infrastructure, including general orchestration of backup, restore and replication tasks, job scheduling and resource allocation .
A disk image is a snapshot of a storage device's structure and data typically stored in one or more computer files on another storage device. [1] [2]Traditionally, disk images were bit-by-bit copies of every sector on a hard disk often created for digital forensic purposes, but it is now common to only copy allocated data to reduce storage space.
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 ...
The ability to directly modify a virtual machine's hard disk from a host server supports many applications, including: Moving files between a VHD and the host file system; Backup and recovery; Antivirus and security; Image management and patching; Disk conversion (physical to virtual, and vice versa) Life-cycle management and provisioning (re)
