the image being recovered is located in Acronis Secure Zone (p. 360) or
when using Acronis Active Restore (p. 360),
because these features are primarily meant for instant data recovery on the same machine.
Universal Restore is not available when recovering Linux.
Unmanaged vault
Any vault (p. 373) that is not a managed vault (p. 369).
V
Validation
An operation that checks the possibility of data recovery from a backup (p. 361).
Validation of a file backup imitates recovery of all files from the backup to a dummy destination. The
previous product versions considered a file backup valid when the metadata contained in its header
was consistent. The current method is time-consuming but much more reliable. Validation of a
volume backup calculates a checksum for every data block saved in the backup. This procedure is
also resource-intensive.
While the successful validation means a high probability of successful recovery, it does not check all
factors that influence the recovery process. If you back up the operating system, only a test recovery
under the bootable media to a spare hard drive can guarantee successful recovery in the future.
Validation rules
A part of the backup plan (p. 362). Rules that define when and how often to perform validation (p.
373) and whether to validate the entire archive (p. 361) or the latest backup in the archive.
Vault
A place for storing backup archives (p. 361). A vault can be organized on a local or networked drive or
detachable media, such as an external USB drive. There are no settings for limiting a vault size or the
number of backups in a vault. You can limit the size of each archive using cleanup (p. 364), but the
total size of archives stored in the vault is limited by the storage size only.
Virtual machine
On Acronis Backup & Recovery 10 Management Server, a machine (p. 369) is considered virtual if it
can be backed up from the virtualization host without installing an agent (p. 360) on the machine. A
virtual machine appears on the management server after registration of the virtualization server that
hosts the machine, provided that Acronis Backup & Recovery 10 agent for virtual machines is
installed on that server.
W
WinPE (Windows Preinstallation Environment)
A minimal Windows system based on any of the following kernels:
Windows XP Professional with Service Pack 2 (PE 1.5)
