Technical data

Allows the automatic validation (validation of data integrity) of the
backup after completion.
8. Archive Comments
Here, you can enter a meaningful comment about the image archive file.
This comment will simplify the identification of the image archive file at a
later time.
9. Proceed
Finishing the wizard and starting the image creation.
For finishing the creation of an image archive file (=backup archive
file), we recommd you to validate it with "Validate Backup Ar‐
chive" under "Explore and Validate Backup Archives" in the main
window.
9.2.5 Validating Image Archives
Image archives serve to backup or archive data. Thus, the data integrity is the
most important property of an image archive. Therefore each image archive is
to be validated after the creation.
To do so, the Acronis True Image main program window provides the "Validate
Backup Archive" function under "Explore and Validate Backup Archives". The
only step after the start window serves to select the image archive file to be
checked. Acronis True Image automatically focuses on the file containing the
last backup. After clicking Proceed Acronis True Image starts to validate the
archive. At the end of the validation a message about the successful action is
displayed.
If Acronis True Image finds an error, the image creation should be
repeated. In this case an other data carrier is to be taken as storage
medium.
9.2.6 Update and Extend Image Archives
It is not required to create a full image during each data backup. For this, the
incremental image creation can be performed. During an incremental image
creation, only the sectors of the partitions or hard disk are saved, that have
been changed since the last complete image creation. This information is saved
as part of the image archive in a new file in the directory of the full image archive.
The name of the new file is the file name of the full image archive in conjunction
with a consecutive number (see note). Incremental image creation is only rea‐
sonable on hard disk or network drives, because using a removable media the
full backup is no longer provided when writing the incremental file.
The archives of the incremental backup are always filed in the di‐
rectory of the selected full backup. The incremental archive files are
marked with a consecutive number at the end of the file name.
Example:
Name of the full image archive: Backup_Drive_C
Name of the 1st incremental archive file: Backup_Drive_C2
Name of the 2nd incremental archive file: Backup_Drive_C3
The incremental backup of a partition is started in the main program window
with the "Backup" function. After clicking on the icon, the wizard for image cre‐
ation starts:
