Title: So what's the difference Post by: RED-DOG on March 20, 2007, 08:49:07 AM Between a CD and a DVD?

Title: Re: So what's the difference Post by: lazaroonie on March 20, 2007, 08:53:04 AM different sized "pits" on the disc - the area which actually holds the data. Which means that the laser in the dvd/cd drive used to read them needs to be smaller.
also they are recorded in a different format. dvd uses UDF format. Title: Re: So what's the difference Post by: RED-DOG on March 20, 2007, 08:54:59 AM DVD's can hold more information Wow, instant info! So if I wanted to back up some files, I could store more on DVD than I could on CD?

Fascinating Title: Re: So what's the difference Post by: Longines on March 20, 2007, 09:06:51 AM [! So if I wanted to back up some files, I could store more on DVD than I could on CD? Roughly, a DVD can hold about the same as 6 CDs. Unless you have a dual-layer capable DVD burner and dual-layer DVDs. Then you're up to 12 CDs to 1 DVD. Title: Re: So what's the difference Post by: M3boy on March 20, 2007, 09:19:22 AM If you are just wanting to backup some files, then get a USB stick - cheaper, more reliable and will hold even more than DVD

Happy days :) Title: Re: So what's the difference Post by: kinboshi on March 20, 2007, 01:01:53 PM Get a 350GB hard drive for less than £50.
Title: Re: So what's the difference Post by: AceofWands on March 20, 2007, 02:01:52 PM Everything you wanted to know about DVD is here: http://en.wikipedia.org/wiki/Dvd
It depends what you want to use if for. If you want something that goes in your pocket for moving loose data between different computers a USB flash drive is easiest. If you are just archiving data, software or music/flims use write-once DVD. These are now so inexpensive. Title: Re: So what's the difference Post by: redsdad on March 20, 2007, 02:29:15 PM I use a flash drive for storing files Tom. Much quicker, much easier to use. mines 256mb. I seem to have put loads of stuff on it and I've used 9%. Put an Icon on your desktop to access it and you can drag files to it.

Title: Re: So what's the difference Post by: Rod Paradise on March 20, 2007, 03:24:44 PM The flashdrives are about £20 for 2M now if you shop around.
Tom I've a 1M that I've stopped using since I upgraded to 2M, you're welcome to it if you want. Title: Re: So what's the difference Post by: RED-DOG on March 20, 2007, 04:27:13 PM I have a programme on my computer called "NTI Backup now 3" (I've never used it) apparently you insert some kind of storage medium and it backs up everything, use it again the following month and it just adds the new stuff.
I would surmise that you need a fair bit of storage space for it to work properly though. PS- Hello dad!! :hello: Title: Re: So what's the difference Post by: Rod Paradise on March 20, 2007, 04:30:31 PM I have a programme on my computer called "NTI Backup now 3" (I've never used it) apparently you insert some kind of storage medium and it backs up everything, use it again the following month and it just adds the new stuff.

PS- Hello dad!! :hello: I think the additional Hard Drive someone's already mentioned is your best bet then some of the cheaper ones are here: http://www.pixmania.co.uk/uk/uk/793/xx/0-88/101/9/criteresn.html (http://www.pixmania.co.uk/uk/uk/793/xx/0-88/101/9/criteresn.html) The programme you're using will backup to the drive (connects using USB2/Firewire). Also if you want to take work away with you it's reasonably portable (if you an get use of another computer wherever you're going).

PS- Hello dad!! :hello: For complete system backups using apps like NTI/Ghost/Acronis you are better off using an external hard drive. You can then use it to back up more than one computer. You can buy really massive drives relatively cheaply now. Title: Re: So what's the difference Post by: TightPaulFolds on March 20, 2007, 05:27:15 PM Be careful about USB storage sticks, they vary in reliability and speed.
Much much handier than burning DVDs though. Title: Re: So what's the difference Post by: happybhoy on March 20, 2007, 06:16:05 PM Dunno if you've got one, but you can use an ipod as an external hard drive as well

I would surmise that you need a fair bit of storage space for it to work properly though. If you want to carry data around with you then a USB stick is fantastic. If you want to backup data and leave it on the shelf then DVD everytime. You do not need to buy 100.... you can just buy 1 or 10 or 25 (best value). You can get a 2 GB stick for about £10 from ebuyer, 25 DVDs for about £5. +P&P. I have no experience with NTI backup now 3, but if it can split the backups accross several DVDs then it will be useful. Are you just trying to make a backup of everything on your PC? In the case of a catastrophic failure you usually need to reinstall windows and the backup program before you can restore the backups, so make sure you have a copy of the program or the backups may be of no use. The way I would suggest to backup is to just copy all your important docs and pics onto a DVD (or 2). There is no need to actually backup windows and all your programs as you can reinstall these if there is a failure (it will take more time, but it is an unlikely event after all). If you want to have a backup that occurs automatically you will pretty much need to get a hard drive, and I would advise an external one for backups as in case of fire you can grab that rather than the whole PC or if there is a theft it may get left behind (here's hoping), or of course you could store it somewhere safe like a safe. But, sticking everything on a DVD is the easiest and cheapest option.

On balance, I think this will be the best/easiest option for me. Thanks to everyone, you're all so knowledgeable. Thanks to everyone for the great advice Title: Re: So what's the difference Post by: Irishdenis on March 21, 2007, 12:07:58 PM Hi Red,
I have put some blank disks in my car for you. Remind me when I see you. When you do your back up you need to make sure you have saved things in the right library etc. Lots of folks keep things in outlook etc but these will not save automatically. Address books contacts etc. Long term you need an external hard drive. You can then mirror your own drive and should you have a failure it will be much easier. I will see what we have here and let you know. Title: Re: So what's the difference Post by: RED-DOG on March 21, 2007, 12:31:06 PM Hi Red, I have put some blank disks in my car for you.
