2IMPORTANCE OF DATA
DATA AS AN ASSET Today data has become
mission-critical to most, if not all, enterprise
applications. The need to have secure data has
become one of the most important priorities for
modern day businesses. Data is now used to
analyze market trends, stay ahead of the
competition as well as being a way to hedge
against legal action. Because of the importance
of data it is now a top priority to ensure data
availability, integrity, and recoverability.
3Data Storage challenge
- As data continues to increase on a daily
basis, two main challenges arise - It gets harder to back up this increasing amount
of data within a rapidly shrinking backup window - When it comes time to restore the data, it
becomes much harder to tolerate long recovery
times -
- In a situation like this things have a
tendency to go wrong. The consequences of losing
allor any partof that data is no longer just a
threat to the job security of the backup
administrator, but also corporate executives who
rely on that data.
4Objectives
- RTO Recovery TIME Objective
- What is an acceptable period of downtime without
damage to the business? - RPO Recovery POINT Objective
- How much data loss can be sustained without
negatively affecting business operations?
5Fulfilling Compliance Requirements
6Staying Power of Tape Technology
- Tape historically is the most used medium for
backup and recovery of primary data storage.
Information Technology professionals have used
tape for archival purposes for a long time. Since
tape is used for such a variety of storage
functions, in organizations of all sizes, it has
almost become a fixture in todays networks.
7Why has tape been the choice
8COST of Backup Media
9Hidden Costs of Tape
10Disk as a backup medium
- This difference in cost between tape and
disk-based systems has until recently been a
barrier to adoption of using hard disk for
archival storage. It is interesting to compare
the costs of disk versus tape media. Only ten
years ago, disk cost 10,000 per GB and tape cost
10 per GB. The recent announcement of a 300GB
3.5 inch disk will for the first time mean that
the per Gigabyte cost of disk will be less than
that of tape media alone. More significantly, it
shows that in only ten years, the cost of disk
has declined by 10,000 times compared to tape
media which has only declined by 10 times. - Current disk technology vendors have all
implemented different kinds of shock protection
in the current disk drives making them viable for
portability. -
- Disk has benefits as a backup media since it is a
random access device and is much faster and more
reliable than tape. -
11DISK VS. TAPE
12What is Idealstor?
Complete Backup System
Idealstor puts a new spin on disk to disk backup
by making disks portable.
13Why Idealstor Disk to Disk Backup?
Backups taking too long
Backup Window is Shrinking
Data Volume Increasing on a regular basis
Questioning Reliability of your tapes
A Lot of Required Maintenance
Considering Disk-to-Disk backups, but they are
too costly and not portable
In the Market for a new Tape Drive or Library
Tired of Slow Tape Technology
Near Line Storage of Archived Data
14Benefits of Idealstor
- Portability
- Scalability
- Flexibility
- Speed
- Maintenance
- Investment Protection
15Traditional Backup Method
- Backup window (tapes are sequential in nature
and are slow) - Calibration Issues with robotic arms in tape
libraries - Tape drive head require periodic cleaning
- Tape head alignment
- Tape reliability (oxide flaking after a period
of time) - Climate sensitive (tapes snap in dry climate)
- Slow restores
- Capacity limitation
16Enhanced Backup Method
- Complexity
- Additional Costs (associated with tape media and
staging appliance) - Additional points of failure
- Data in more places at varying points in time
- Wont replace tape for Archival backups
- Limited storage
17Idealstor Backup Method
Idealstor Backup Disk-to-Disk In order to
address off-site storage, Idealstor uses disks
like tape, giving you best of both the
technologies, it offers the speed and reliability
of disk and the portability of tape. Idealstor
offers a backup platform that for the first time
outperforms tape drives and libraries in
performance, reliability, scalability, ease of
use and functionality. Idealstor can be easily
deployed and is compatible with all existing
major backup software. It takes away the
headaches, pain and expenses normally associated
with tape based backup systems.
