The Problem

40% of enterprises that experience a disaster will go out of business in five years.

Only 15% of enterprises have a full-fledged business continuity plan that goes beyond core technology and infrastructure

(Source: Gartner)


The Implications

High availability of critical business systems is no longer a luxury restricted to large businesses ― it is a competitive business requirement for everyone.


How We Are Going to Help You

You may feel that you don’t have the budget for proper disaster recovery solutions but…

Start with what you have…iFolder®

Archive ServicesSnapshotsBackupsClustering

Go to where you need to be…Business Continuance Clustering


Before we start…

Don’t try to make a square peg fit into a round hole.


Problems of Personal Data Availability

A disk failure on one of your personal systems could be a serious disaster.

Sensitive Company data is often stored on employee’s computers/laptops and not backed up regularly.

You don’t dare store your sensitive data on the Internet.

1 out of 1,000 laptops are stolen; 10% are targeted for their data.


What’s in iFolder 2.1?

iFolder 2.1 is bundled in NetWare 6.5 and includes:

Automatically and transparently synchronize files to iFolder server and your other machines through any standard Internet connection

Encrypt files delivered to, and stored on, the server to protect them from unauthorized access

Secure access to your files from a Web browser

Scale to millions of users - Cluster multiple iFolder servers under a single DNS name

PDA access to iFolder files

Ability to choose location of local iFolder


Novell iFolder®

Backup

Synchronize

Access

Instant access to your files— online, offline, anytime


Novell iFolder Summary

Novell iFolder lets your files follow you—everywhere

Automatically backs up your local data

No matter where you are, your files are always with you

Simplifies the way files are used across the Net

Files are always safe, secure, and up-to-date

Secures and protects corporate digital assets

Accelerates the productivity of today’s mobile professionals


Backing Up User Data

When users store data on servers there are still problems

Users generate a LOT of data

You don’t want to backup up some of what they create – for example, MP3s

Restoring individual files is time consuming and costly

Your time between backups affects your ability to recover from user errors


File Archiving

Built on Novell’s File based Epoch Event File System Technologies in NetWare® 6.5Takes scheduled file level (not block) snapshots

Keeps Archives on Archive volume or separate Archive server

– Archive server can be any OS platformCan designate which subdirectories and/or file types to archive and when

– Great flexibility for shared user foldersNetStorage Interface for User self restore of previous file versions

– Users can view previous versions and decide which to restore

– Indicates the user who last modified the particular version


How Does Archiving Work?

Archiving Summary

The Novell Archive / Version Services allows individual users to restore previous versions of modified, lost, or deleted files.

This feature is great for workgroups working on files in shared folders or personal files on the server

Provide a lower cost of management for IT departments by allowing users to self restore files.

Provide a means to allow users to be more productive by allowing them to correct their own mistakes.


Backing Up Databases

How do you backup up applications like databases and mail systems?

There is usually a requirement to stop the application to get a consistent backup.

This conflicts with application availability requirements.


Snapshot Technology

Creates a virtual image of the pool at that moment

Not a full copy of the pool

Cannot be used to restore a deleted original pool

Uses Copy On Write to save changes

Main purpose is to allow backup of open files

Can be used to restore deleted or corrupted files


How snapshot works

Stored-on PoolData Pool

At creation time, all the data for a Snapshot Pool comes from the original Data Pool. No data is actually stored in the Snapshot.

How snapshot works

Stored-on PoolData Pool

Changes to the Data Pool causes the old data to be copied to the Stored-on Pool. The Snapshot Pool gets its data from both.

Snapshot Summary


Snapshot Summary

Snapshot is independent of hardware vendor,even mix of vendors.

Snapshot tools integrated into console

Anytime backup

View & select file versions


Data Vulnerability

Data is usually in one location, even on one server

How do you deal with the loss of that location – for example, fire or flood?


RAID1 (Mirroring)

Mirroring completely rewritten for NetWare 6.5

Faster Remirroring - Saves blocks mirrored on the disk. Remirrors only necessary blocks after an Abend or power down.

Add mirroring at any time - No need to set up mirror objects at partition creation time.

Mirrored pools can be seen by all nodes in a cluster.

Fully multi-processor enabled.

Scalable – Same size memory for all size partitions

Novell iSCSI Summary

Target • An inexpensive way to turn your existing direct attached

storage (DAS) server hardware into a flexible and manageable SAN solution for your Net Services

• NetWare 6.5 only• Integrated with LDAP for Directory based management

Initiator• Ensure NetWare works with open standards

and standard Storage Solutions• NetWare 5.1 and above• Offer direct and indirect SAN benefits to customers who

typically would not purchase expensive Fibre Channel SANs

• Makes server to server mirroring affordable


The Down Time Problem

File transfers and file storage

Calendaring and collaboration

Web hosting

Critical databases

How much does down time cost?

How it Works


Replicating the Data

Things to consider:

Host-based vs. Disk-based replication

Asynchronous vs. Synchronous

Distance: 100 m, 1k, 100k, … around the world

Required bandwidth for replication?

Latency of the link? Latency tolerance of the application?

Final Summary

Start a disaster recovery plan based on what you have right now.

Plan to grow to a complete business continuity solution a step at a time.

But remember…

Each solution has it’s own niche; don’t try to make a square peg fit into a round hole.
