The Image Approach

SnapBack Live! takes a completely different approach to

the backup process. Rather than going through the server

file system to access server data, a full binary data image

is copied directly from disk to tape.

Absolute Backup

The SnapBack backup image contains everything on the

server drives - the entire operating system, special server

files, patches, updates – EVERYTHING. Problems with

missing open files, separate restoration of security and the

operating system, and re-installation of the backup software

are solved completely.

During backup, SnapBack monitors all server disk activity.

Open file and system writes are recorded in a dynamic

caching system until they are committed to tape. This

eliminates any problems with open files or the need for

costly application-oriented add-on programs.

Peak Performance

Bypassing the server file system gives SnapBack an

unparalleled advantage in backup performance. While file-

based systems must traverse directories, check permissions

and open, read, and close all files, SnapBack reads and

writes directly to hardware. SnapBack monitors user access

and momentarily suspends backup operations when users

require server resources. The result is the fastest possible

backup – without any perceptible decrease in server

response to users.

Total Recall

SnapBack restore runs from any DOS bootable floppy. The

recovery process is simple and direct. Boot to DOS from a

floppy, put the tape in the drive, then restore the drives.
