Acronis True Image User’s Guide

This boot manager is required for Acronis Secure Zone to work. If the boot manager

is absent, the zone creation wizard will be run (see above). The restoration

manager will be installed during this procedure as well.

If there is Acronis Secure Zone on your PC, the boot manager will be activated

immediately.

3.4 Incremental images

An incremental image contains only data from those hard disk sectors that changed

after the previous disk image (complete or incremental) was created. Thus such an

image is significantly smaller and takes less time to create than a full image.

However, as it does not contain all the necessary information about disks

(partitions), it requires more than one image for restoration, including the current

incremental image and at least one previous image or, ideally, all the previous

incremental images and the initial complete image. You can't foresee the exact

number of images required for a particular restoration, as it depends on how much

data changes between image creations.

Note that you can create incremental images more often, as they are far smaller

than complete images and take significantly less time to create. If you create such

images often, you'll be able to restore disks (partitions) relatively easily and quickly.

If you just use complete images, this will require far more time and space (up to 10

times more).

An incremental image created after a disk is defragmented might be considerably lar

er than

usual. This is because the defra

mentation pro

ram chan

es file locations on disk and

incremental images reflect these changes.

Using incremental stages instead of complete images gives you more flexibility in

what you restore. It takes much less time and as little as one tenth the disk space.
