Be careful! Disk letters in standalone Acronis True Image Echo Server might sometimes
differ from the way Windows identifies drives. For example, the D: drive identified in the
standalone Acronis True Image might correspond to the E: drive in Windows.
3.5 Acronis Snap Restore
With this feature you can boot the OS on a crashed computer before the system is
completely restored from an image and start work seconds after the restoration is
launched. The restoration will be continued in the background.
3.5.1 Limitations in using Acronis Snap Restore
1. Acronis Snap Restore is currently available for images located in the Acronis Secure
Zone only.
2. Acronis Snap Restore does not support images of Windows Vista. If any Vista edition is
detected in an image, the Snap Restore option will not appear.
3. Acronis Snap Restore does not work if the image contains dynamic disks and volumes.
4. Acronis Snap Restore cannot be used if the image contains no operating system (a
logical partition or disk image) or when restoring file archives.
3.5.2 How it works
When the restoration procedure is started, Acronis True Image Echo Server:
1. Finds the sectors in the image which contain system files, and restores these sectors
first. First the OS is restored and can be started very quickly. Having started the OS, the
user 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 system
queries to the files. When the user attempts to open files or launch applications, the
drivers receive the system queries and restore the sectors that are necessary for the
requested operation.
3. At the same time, Acronis True Image Echo Server proceeds with the complete sector-
by-sector image restoration in the background. However, the requested sectors have the
highest priority.
Finally, the image will be fully restored even if the user performs no actions at all. But if
you choose to start working as soon as possible after the system failure, you will gain at
least several minutes, considering that restoration of a 10-20GB image (most common
image size) takes about 10 minutes. The larger the image size, the more time you save.
