What Does the Administrator
Do?
The administrator initializes the system, defines backup settings as appropriate, and
monitors backup status for all protected computers.
In the event of disk failure on a protected computer, the administrator can create a
disaster recovery CD-ROM for the client (the user of the protected computer) from

the HP SureStore AutoBackup appliance.
If you have purchased the optional HP SureStore Tape drive, the administrator is also
responsible for backing up the appliance to tape for offsite storage. In the event of
appliance failure (for example due to fire, earthquake or hardware failure), the
administrator can then recover the whole system using new hardware.

Product Overview
HP SureStore AutoBackup provides a complete automated solution for backing up
data held on desktop and mobile PC hard disks that are connected across the network
to the HP SureStore AutoBackup appliance.
HP SureStore AutoBackup consists of a customized server (or appliance) with
internal HP SureStore CD-Writer and customized backup and restore software. It is
designed to attach to an existing LAN in small to medium size companies or
workgroups, so that users (or clients) on desktop PCs or remote PCs can
automatically back up data from their local hard disks across the network to the HP
SureStore AutoBackup appliance.
Note: The modems for remote dial-up must connect to an NT server or workstation.
The AutoBackup backup and restore processes are completely unobtrusive and are
carried out while the user is online and working with the desktop or mobile PC.

Additional Appliance Disaster
Recovery Protection
HP SureStore AutoBackup also supports connection to an optional, external HP
SureStore tape drive, as shown on the above illustration. This allows backup of the
appliance itself. Hewlett-Packard strongly recommends this feature to protect your
data from disasters such as fire, earthquake and data critical hardware failure.

Product Overview
What Is HP SureStore
AutoBackup?
HP SureStore AutoBackup provides automatic backup of data held on the local hard
disks of PCs connected to a network. The PCs protected by HP SureStore
AutoBackup, also called clients, may have either fixed or remote access to the
network.
Administrators access HP SureStore AutoBackup via a web-based console for
normal administration tasks. They can also download an Advanced Administration
console. Users (or clients) install the HP SureStore AutoBackup Agent software via
their web browser, and can then run the HP SureStore AutoBackup Agent from their
PCs.
Backup Strategy
Typically, the strategy is to create a full daily backup of the entire data on the local
hard disk (the C: drive and any additional partitioned drives), where the backup is set
to run automatically in accordance with a defined schedule. Although the first
backup after installation may take a little time to run because it backs up all the data,
subsequent daily backups will take just a few minutes because it only writes changed
data to the appliance. When running, the automatic backup is transparent to the user,
who can continue working on the PC.

Once the data has been backed up, file restore is a simple drag and drop operation
from Windows Explorer - with clients only ever able to access their own data on the
server. This significantly simplifies the ability to restore backed up files, compared
with magnetic tape, and allows restores to be carried out without IT department
involvement.

In the event of a client disaster, the administrator can create a disaster recovery
CD-ROM (and boot floppy. if required), so that the user can reset their connection to
HP SureStore AutoBackup and restore their data once their hardware has been
repaired or replaced.
Use for Backup - Not as Archive
It must be recognized that HP SureStore AutoBackup is designed for relatively
short-term file restore rather than long-term archiving. Although it allows different
versions of the same file to be restored according to backup date, the earliest versions
of a file are overwritten after a specified time period. Any files that are deleted on the
client's PC will also be deleted on the appliance after a specified time. See Retention
Limit for further details.

Product Overview
Why Use HP SureStore
AutoBackup?
Most companies have a system where individual PCs (clients) are linked together on
a network so as to provide shared resources such as printers. Clients also usually
have access to a shared network drive and are instructed to save all their important
files to the network drive, which will be backed up at regular intervals by the IT
department, for example to magnetic tape. If a client needs to restore files, they must
request the IT Administrator to locate the backup tape and restore the relevant file(s)
back to the network drive.
In practice many users will work on and store important files, especially "work in
progress", on their hard disk. These files are only backed up if the user regularly
copies them to the network or regularly uses some form of backup directly at their
individual PC, such as floppy disk, CD-ROM, magnetic tape.

Without HP SureStore
AutoBackup
Backup of the local hard disk is solely the responsibility of the user, is
time-consuming and is not always straightforward.
A company has very limited control over whether potentially important files
are actually backed up.
If the connection is made via a remote dial-up modem, the transfer time can
be so slow that users of laptops or mobile PCs will postpone backing up their
local hard disk.
Because of the nature of mobile PCs, the data is also at greater risk to loss,
theft or damage compared to desktop PCs, and shares the same risk of disk
failure, viruses, Operating System (OS) corruption, and so on.
Even in cases where it is certain that all users are working from the network
drives, a company is potentially wasting resources. Typically, new PCs have
at least 4 GB hard disks as standard. If these disks are only used for OS and
applications programs and no data, there is potentially a very large storage
capacity across the company that is not used.
