Use your DVD Backup And Copy functionality!
Today Desktop computers often have DVD Backup And Copy capabilities built in to their CD/DVD drive. This inbuilt dvd burner enable a practical and convenient way to backup your hard drive to another data medium with a DVD data and copy software.
DVD can also be used with hard drive backups on network servers!
You should look for a player with burner capacity that can work with both CD and DVD.
If you want a CD-RW backup look here! For the player to work with both CD and DVD it must be equipped with two different lasers that work in different wave lengths. This is because CD and DVD use different track size.
There are four standards to consider when using a DVD player for DVD backup and duplication purposes. In fact it is a kind of mess.
They are DVD+RW, DVD-RW, DVD-R and DVD-RAM. There are two competing consortiums each one promoting either DVD+RW or promoting DVD-R(W) and DVD-RAM.
DVD+RW
The DVD+RW are read and writable with 4.7 GB capacity on a single side. A double sided DVD+RW can read and write 9.4 GB. The DVD+RW standard is being supported by companies like Yamaha, Sony, HP, Philips, Ricoh and Dell in the DVD+RW Alliance. This is the newest of the DVD standards.
It is possible to play DVD created in a DVD+RW drive of some of the DVD-ROM drives available today. The DVD+RW disc can be played backed on newer versions of DVD-RW players. But this is not the case with all DVD-RW players.
Microsoft recently announced that they will support the DVD+RW standard.
DVD-RW and DVD-R
This is a DVD standard developed by Pioneer, Yamaha and Richo. It has been supported by the DVD-consortium. The DVD-RW standard discs are also a rewritable like the DVD+RW standard. With the DVD+R standard you can only write on the DVD disc one time. With the DVD-RW you can record about 1000 times, which is enough for most DVD backup purposes. You cannot record multiple sessions and append recording or files on a DVD-RW disc.
DVD-RAM.
DVD-RAM (Read Add Memory) is competing with DVD-RW and DVD+RW.
Behind DVD-RAM is the DVD-consortium which is also behind the DVD-R(W) standard. The DVD-RAM standard uses a special cartridge for recording and playing and is therefore incompatible with the other standards. It was first limited to 2.4 GB. But there are now versions up to 9.4 GB.
The main disadvantage is that they can only be use on DVD-RAM players.
Because of the limitations with DVD-RAM we can disregard this standard for dvd backup and copy purposes.
Of the two multiple DVD+RW and DVD-RW standards, the DVD+RW is a later standard and is slightly more expensive. What you should look for is DVD player is that it should support both standards.
Although many use DVD burner only to copy DVD's more and more find that they can use the DVD burner for backup purposes.
The DVD backup and copy software you use should also support the DVD+RW and the DVD-RW standards.
To backup your data from a PC to a DVD disc is both a practical and convenient way to secure youre data.
You can have a DVD disc installed on the drive and have a DVD copying program installed and let it backup the files that you want to backup on regular intervals. You can make a complete backup to one or more DVDs from your hard drive with a DVD storage enabled software product.
