ACRONIS Backup & Recovery 10 Advanced Workstation Betriebsanweisung PDF herunterladen (Seite 260)

The full version of Acronis Disk Director will provide more tools and utilities for working with

volumes.

Acronis Disk Director Lite must obtain exclusive access to the target volume. This means no other disk

management utilities (like Windows Disk Management utility) can access it at that time. If you receive a

message stating that the volume cannot be blocked, close the disk management applications that use this

volume and start again. If you can not determine which applications use the volume, close them all.

Creating a volume

You might need a new volume to:

 Recover a previously saved backup copy in the “exactly as was” configuration;

 Store collections of similar files separately — for example, an MP3 collection or video files on a

separate volume;

 Store backups (images) of other volumes/disks on a special volume;

 Install a new operating system (or swap file) on a new volume;

 Add ne w hardware to a machine.

In Acronis Disk Director Lite the tool for creating volumes is the Create volume Wizard.

Types of dynamic volumes

Simple Volume

A volume created from free space on a single physical disk. It can consist of one region on the

disk or several regions, virtually united by the Logical Disk Manager (LDM). It provides no

additional reliability, no speed improvement, nor extra size.

Spanned Volume

A volume created from free disk space virtually linked together by the LDM from several physical

disks. Up to 32 disks can be included into one volume, thus overcoming the hardware size

limitations, but if at least one disk fails, all data will be lost, and no part of a spanned volume may

be removed without destroying the entire volume. So, a spanned volume provides no additional

reliability, nor a better I/O rate.

Striped Volume

A volume, also sometimes called RAID 0, consisting of equal sized stripes of data, written across

each disk in the volume; it means that to create a striped volume, a user will need two or more

dynamic disks. The disks in a striped volume don’t have to be identical, but there must be unused

space available on each disk that you want to include in the volume and the size of the volume

will depend on the size of the smallest space. Access to the data on a striped volume is usually

faster than access to the same data on a single physical disk, because the I/O is spread across

more than one disk.

Striped volumes are created for improved performance, not for their better reliability - they do

not contain redundant information.

Mirrored Volume

A faul t-tolerant volume, also sometimes called RAID 1, whose data is duplicated on two identical

physical disks. All of the data on one disk is copied to another disk to provide data redundancy.

Almost any volume can be mirrored, including the system and boot volumes, and if one of the

disks fails, the data can still be accessed from the remaining disks. Unfortunately, the hardware

limitations on size and performance are even more severe with the use of mirrored volumes.
