Introduction—Why SnapBack?

INTRO

SnapBack Live! uses a novel approach to server data

backup and restoration. This chapter will examine the

problems with conventional backup technologies, explain

the unique solution provided by the SnapBack system, and

summarize the benefits and limitations.

Backup Blues

Most backup systems provide a great deal of activities for

administrators and users. The backup software requires lists

of included and excluded directories because servers

sometimes become inaccessible and because special

modules purchased, installed, and configured for

applications may will be running during backup. In

addition, backup operators require security rights for

everything. The backup software often needs maintenance

when security rights are modified or applications are added

or deleted. Even after a backup system is properly set up,

the administrator needs to review backup logs to ensure that

the essential files aren’t skipped because somebody in

shipping left an order screen open before heading to Happy

Hour.

Complex Recovery

Restoring a system can be a challenge as well. A disaster

recovery can involve re-installing the underlying operating

system; recreating user security profiles; re-installing the

backup software; and, finally, restoring the application files.

During this process the administrator is praying that the

customer transactions weren’t skipped because of that

clown in shipping or a key directory from the new SQL

manager wasn’t omitted from the inclusion list.
