There are certain factors that a good device would satisfy. It should offer enough storage space, be easy to carry, accommodate all file formats, be easy to share from, and more or less hardy. Not all portable digital media were able to support and accommodate all these demands. Constant upgrading is another catchword to survive in the market, and those could not do it were left behind in the race. That was the fate of the floppies and the LD. In the following, one of the most successful formats -- the DVD-- has been discussed.
t are DVDs?
What is a DVD? It stands for Digital Video Disk and the nomenclature denotes its original use. It was invented to store audiovisual information in high quality digital format for distribution and backup. The DVD is an optical disk on the surface of which data is written in clusters that can be seen as rings with the naked eye. This means that the data is written in spirals on the shiny surface and is exposed to the elements just like the CD. However, the DVD offers more space and far better audiovisual reproduction quality than a CD.
antages of DVD as a Format
The DVD has several advantages that have helped it to gain popularity in the highly competitive digital goods market.
It has more storage space than the CD or floppy. The floppy had anyhow been ousted by the CD, and the DVD was like its death knell. The storage space offered also helped in retaining various kinds of file formats.
The DVD drive in the computer can usually read and record data on CDs too. The combo drive as it was formerly called, has now totally captured the domestic market and is the accepted hardware component for all laptops and desktop pc.
The better quality of reproduction has made the DVD the first choice for audiovisual file formats. Be it photographs or movies, DVDs are everyone's choice for media files. It has also grabbed the film reproduction and distribution market from the CD, both as branded and pirated versions of movies, music video compilations and television programme compilations.
The DVD is easy to carry and very handy for usage. It can be inserted and played on any computer with a DVD drive. This makes the information in it easy to share.
The DVD also accommodates all file formats, making it easy to store downloaded content into it.
The DVD is also very cheap and available in attractive get-ups, with DVD bags, jackets, albums and towers to store it.
advantages of DVD as a Format
There are some disadvantages as well.
The DVD is still somewhat costlier than the CD.
The DVD is also susceptible to virus infection easily because of its ready sharing advantage.
Mass production has affected manufacture and some cheap DVDs are created with inherent faults.
File formats may be corrupted and fragmented owing to over-compression, size, mishandling and manufacturing flaws.
The DVD is waterproof, but not resilient to dust, heat, humidity, shock or fire. The exposed data can easily be physically damaged.
DVDs getting stuck in trays and creating a serious threat for the entire system is a common menace. The USB devices have scored higher in this regard.
The DVD still does not have the kind of space that a portable hard disk would offer. It has less storage space than even the USB drive.
How Good for Data Storage
How does one rate the DVD as a data storage device? The pros and cons listed above should give an idea about its viability and weaknesses. There is no denying the fact that the DVD is indeed quite popular as a data storage device, especially for movies.
Why Suited for Data Backup
Why would the DVD be used for data backup?
Its large storage space suits it for domestic data backup purposes.
Audiovisual files stored on the hard disk are a clumsy matter for both home and office users. It is best to copy out such information and free the disk space.
It is cheaper than USB drives and a pack of DVDs can afford us with lots of backup space.
Future Prospects for DVDs
The future prospects of the DVD look bright enough. It would probably develop further features and offer more space.
Competitors of the DVD
The CD, USB drives and portable hard disk may offer competition to DVDs.
Dvd Data Backup Software
The concept of offsite data backup is not new; some time ago it was only available to corporate institutions that had multiple locations, high connectivity speeds and very high budgets. Today the cost of hardware and high speed connectivity has greatly reduced, as a result the number of companies offering backup to a remote location has greatly increased. For purposes of conversation, we can call it jumping on the band wagon.
You may think the increased competition is good for the consumer, to an extent, I agree, but not at the cost of cutting corners and jeopardising the security of your data. We all know and agree a company's data is its most important asset, and to lose or give access to your competition such an asset is never an option. So please be careful where you store your data.
The general idea of offsite backup is a good one, after all it has a very low proportionate implementation cost and as the correct system should be completely automated the cost of ownership is also very low as well. Unlike tape backup it is also very scalable, you can start small and grow into larger solutions as and when you require with zero disruption but you have to be with the right offsite backup company in the first place.
In today's data centric environment even smaller companies may have more than one server, just for example a server for Microsoft Exchange/Lotus Notes, a server for Microsoft SQL/Oracle/MySQL and potentially a file and print server, or maybe a single server which carries out all tasks. Smaller companies may still use older inherited Unix based or Novell based systems or may be considering migrating to a lower cost Linux environment. Whet ever you currently use or what you may use in the future your offsite backup solution will need to adapt. Please check, what ever backup company you use, make sure they are always developing their products for the future, your companies future.
Getting data to an offsite location is the easy bit, anybody can click and drag to an ftp site, to optimise your backup and more importantly your recovery times make sure your data is compressed locally or at source. The most important element of any data transfer is security, make sure your data is encrypted before it is transmitted and remains encrypted whilst in storage if this is the case only your organisation will have access to your data.
In what environment is your data stored? There is no point just moving your most important asset to another location, make sure it is totally safe, data should only be backed up to a class 1 data centre with the highest security and safety measures in place, hardware should be clustered so there is no single point of failure within that data centre and for added security and peace of mind the whole data centre and hardware within should be a replicated in real time to a second location in preferably another country.
Imagine your local data backed up every night or when ever you wish to a secure remote location in the UK and then replicated in real-time to a second data centre in a different country.
Finally this whole process must be as efficient as possible. It must be totally secure, fully automated ensuring your staff are focussed on revenue generating functions, it must support open files enabling you to backup regardless of what your systems are doing and it must be capable of incremental backups, after all there is no point re-transmitting a file which has not been accessed for a year.
So after reading this article I now hope it has made you think and understand why the cheapest offsite backup solution is rarely the best.
