Backing up a back up

[CoffeeGuy]

I am fairly new to "dvd to dvd-r", and have had great success backing up my dvd collection. Many thanks for dvdecryptor & dvd shrink. What a nice gift ? Now, for my somewhat dumb question. I think I know the answer, but would like a comfirmation. If I should lose or damage my primary dvd, would I be able to back up my back up ? Would I have to go about it in the same manner as I did with my primary dvd ? My guess is no, since it has been decrypted already. I'm guessing I could copy from disc to disc using nero express. But would the backed up back up have any noticable loss of quality using this method ?

Backing up a "back up" DVD-R is identical to disc-to-disc copy or backing up a DVD5 (use DVDDecrypter, do ISO read then ISO write).

The answer is yes, you can use NERO and no you won't loose any quality. A copy is just that an exact copy!

1. Insert your backup into your reader.

2. Insert a blank into your writer.

3. Fire up Nero, EZ-Coaster-Creator, or any other program that burns discs.

4. Hit "copy disc".

5. Wait 20 minutes.

6. Done. YAY!

I would advise against doing on the fly copies of DVD media. It's possible and several people report doing so without errors but to be safe I would generate an ISO image file on the HD then burn that. Here's what you do:

1) D/load and installed DVD Decrypter
2) Choose "Mode | ISO - Read" and rip ISO Image file to HD
3) Choose "Mode | ISO - Write" select image file then burn

That's it. This is the recommended method for all DVD5 (ie. single layer) backups.

Here is the easiest was to backup a 'Backup'

1) Inset DVD in drive.

2) Go to my computer and open dvd.

3) Drag all the Folders/Files to HD

4) Burn to DVD with nero.

There is no need to decrypte anything since you decrypte it before you
backup it up previously.

Ya'll realize none of these methods work if there's an error on the disk.

If you have a crappy burn on the original DVDR, then you have to rip it with DVDDecryptor and force it to ignore errors. ISO READ/WRITE works fine this way.

Mixman380 - you're right that drag/drop will work for unencrypted data. However, it's almost always faster to rip the data then to copy it. I can rip unencrypted DVD5 discs at 8-15x, let's call it 10x ot 13.8MB/s I can't copy that fast in winXP

Also for multiple backup copies it's nice to have the one ISO image file instead of several VIEDO_TS folders. And finally not everyone has Nero or a commerical burning program. Many (myself included) use only freeware tools (IMGTools + DVD Decrypter) and that requires an ISO Image file as the source.

i like this drag and drop when i go in to nero what do i pick to burn it with
