Technical data
It is not recommended to archive images directly on removable me‐
dia like e. g. CDs or DVDs, as a flow control of the data is missing
because of the direct writing on these data carriers. Furthermore,
we recommend you to divide the image archives during the creation
into the corresponding size and to transmit the files after the backup
process to the removable media and to verify them.
Images of partitions contain all files and directories, independent of their prop‐
erties (hidden, system, etc.), the Master Boot Record (MBR), the File Allocation
Table (FAT) and the Root directory.
In a partition image only the hard disk sectors containing user data are saved.
The image archives can be protected with a password.
Incremental Backup
An image archive contains one or several images. Generally, these are com‐
pressed copies of partitions or entire drives. It is not only possible, to record
several partitions or hard disks in an archive file and to restore them separately,
the data of an image archive can also be updated. To achieve this, a technology
is used, that is similar to the incremental data backup. Thereby, only the data
modified since the last image creation are saved. This process (differential
backup) saves time and memory space. Please consider that the basis of an
incremental backup is always a preceding full disk backup. Therefore, the soft‐
ware analyzes at first, if an incremental backup is possible. If a full disk backup
does not exist, it is always created at first.
Further advantage of incremental backups: The recovery of a partition from the
image archive is possible with different states generated from different image
creation times. Not only the image of the respective last backup, but also e. g.
the image created at a certain time in the past can be restored.
9.2.3 Acronis Secure Zone und Startup Recovery Manager
Acronis Secure Zone
In the case, that local partitions are damaged and e. g. cannot boot anymore,
but the physical state of the HDD is still alright, it is possible to restore images
locally from the Acronis Secure Zone.
The Acronis Secure Zone is a zone on the hard disk, that is inaccessible by
ordinary Windows applications. Image archives for quick recovery of partitions
or hard disks can be safely archived in this especially protected hard disk par‐
tition. Additionally, the Acronis Secure Zone includes parts of the Acronis
Startup Recovery Manager, with which the Acronis True Image can be activated
in error case before starting the operating system and with which a corrupted
system partition can be recovered. Thus, partitions can be recoverd, even if the
Windows operating system does not start anymore. Also the rescue media to
start Acronis True Image is not required, as the information to execute the pro‐
gram is integrated in the Acronis Startup Recovery Manager.
The Acronis Secure Zone is created as logic drive in the extended
partition. The used file system is FAT32. It cannot be accessed via
a drive letter. Furthermore, no direct access to the image archives
is stored there, except for Acronis True Image itself.
Acronis Startup Recovery Manager
The Acronis Startup Recovery Manager is a boot manager with a Linux mini
operating system, with which Acronis True Image can be started by pressing
the F11 key, independently from the installed Windows, before a possibly dam‐
aged operating system boots. The main task of the Acronis Startup Recovery
Manager is the recovery of damaged operating system partitions. Also other
partitions can be recovered or backed up. The Acronis True Image started from
Acronis Startup Recovery Manager offers all functions, that are also possible
during the start of a rescue media.
