Mounting partition images

Acronis True Image Server for Linux can mount partition images, thus letting you access

them as though they were physical drives. This means that you will be able to use the virtual

disk in the same way as the real one: open, save, copy, move, create, delete files or folders.

If necessary, the image can be mounted in read-only mode.

Please keep in mind that, though both file archives and disk/partition images have a default “.tib”
extension, only partition images can be mounted. If you want to view file archive contents, use the
Restore Data Wizard (see

6.2 Restoring files and folders from file archives

, steps 1-9).

The current version of Acronis True Image Server for Linux can mount an image archive only if all its
volumes reside in the same directory. If your archive spans several CD-R/RW discs and you wish to
mount the image, you should copy all volumes to a hard disk drive or network drive.

9.1

Mounting an image

1. Invoke the

Mount Image Wizard

by clicking on the

Mount Image

operation icon in

the main program window.

2. Click

Next

.

3. Select the archive from the drives tree. If the archive is located in Acronis Secure Zone,
select it to choose the archive at the next step.

If you added a comment to the archive, it will be displayed to the right of the drives tree. If

the archive was protected with a password, Acronis True Image Server for Linux will ask for

it. Neither the partitions layout, nor the

Next

button will be enabled until you enter the

correct password.

4. Click

Next
