30 Copyright © Acronis, Inc., 2000-20093. Acronis Active restore does not work if the image contains dynamic disks and volumes.4. Acronis Active restore cannot be used if the image contains no operating system (alogical partition or disk image) or when restoring file archives.3.6.2 How it worksWhen the restoration procedure is started, Acronis True Image for Microsoft SmallBusiness Server:1. Finds the sectors in the image which contain system files, and restores these sectorsfirst. First the OS is restored and can be started very quickly. Having started the OS, theuser sees the folder tree with files, though file contents still is not recovered.Nevertheless, the user can start working.2. Next, the application writes on the hard disk its own drivers, which intercept systemqueries to the files. When the user attempts to open files or launch applications, thedrivers receive the system queries and restore the sectors that are necessary for therequested operation.3. At the same time, Acronis True Image for Microsoft Small Business Server proceedswith the complete sector-by-sector image restoration in the background. However, therequested sectors have the highest priority.Finally, the image will be fully restored even if the user performs no actions at all. But ifyou choose to start working as soon as possible after the system failure, you will gain atleast several minutes, considering that restoration of a 10-20GB image (most commonimage size) takes about 10 minutes. The larger the image size, the more time you save.3.6.3 How to useTo be able to use Acronis Active restore, prepare your system this way: (you can do iteither locally, using Acronis True Image for Microsoft Small Business Server local version,or remotely using Acronis True Image Management Console):1.

Create the Acronis Secure Zone on the local computer hard disk (seeChapter 9.Managing the Acronis Secure Zone).3. Activate Acronis Startup Recovery manager (see3.4 Acronis Startup RecoveryManager) and create bootable media or RIS package with Acronis True Image forMicrosoft Small Business Server (seeChapter 10. Creating bootable media).4. Back up (image) the local computer’s system disk to Acronis Secure Zone (see6.2Backing up disks and partitions (image backup)). You can back up other disks/partitionsas well, but the system image is mandatory.When performing Active restore, the current Acronis True Image for Microsoft SmallBusiness Server version always restores the entire system disk. Therefore, if your systemdisk consists of several partitions, all of them must be included in the image. Anypartitions which are missing from the image will be lost.If failure occurs, boot the local computer from the bootable media, or RIS server, or usingF11. Start the recovery procedure (see7.3 Restoring disks/partitions or files fromimages), select the system disk image from Acronis Secure Zone, choose Use Activerestore and in the next window click Proceed. In a few seconds the computer will
