Static group

A group of machines which a management server (p. 247) administrator populates by manually

adding machines to the group. A machine remains in a static group until the administrator removes it

from the group or from the management server.

Storage node (Acronis Backup & Recovery 11.5 Storage Node)

A server aimed to optimize usage of various resources required for protection of enterprise data. This

goal is achieved by organizing managed vaults (p. 247). Storage Node enables the administrator to:

 use a single centralized catalog (p. 242) of data stored in the managed vaults

 relieve managed machines (p. 247) of unnecessary CPU load by performing cleanup (p. 241),

validation (p. 249) and other operations with backup archives (p. 238) which otherwise would be

performed by agents (p. 238)

 drastically reduce backup traffic and storage space taken by the archives (p. 238) by using

deduplication (p. 242)

 prevent access to the backup archives, even in case the storage medium is stolen or accessed by

a malefactor, by using encrypted vaults (p. 245).

Task

A set of actions to be performed by Acronis Backup & Recovery 11.5 at a certain time or event. The

actions are described in a non human-readable service file. The time or event (schedule) is stored in

the protected registry keys (in Windows) or on the file system (in Linux).

Tower of Hanoi

A popular backup scheme (p. 239) aimed to maintain the optimal balance between a backup archive

(p. 238) size and the number of recovery points (p. 248) available from the archive. Unlike the GFS (p.

245) scheme that has only three levels of recovery resolution (daily, weekly, monthly resolution), the

Tower of Hanoi scheme continuously reduces the time interval between recovery points as the

backup age increases. This allows for very efficient usage of the backup storage.

For more information please refer to "Tower of Hanoi backup scheme (p. 47)".

Unmanaged vault

Any vault (p. 250) that is not a managed vault (p. 247).

Validation

An operation that checks the possibility of data recovery from a backup (p. 238).
