Can I backup a dvd backup?

[Ally7]

I found (thanks to some advice above) that using dvd xcopy - you can back up the back up by transferring the video_TS file to HD and then burn. Works perfect in uk on updated x copy prods - using browse facility to get file to burn - may work on originals.

You may be an engineer, but you are truely clueless. If proper media, like lordsmurf said, the 1 millionth copy will be the same as the first. You also do not need a 2 gig pentium 4 to burn dvd's. I am sill waiting for you ignorant reply to that one. Could we have an indolikaa special please?

Exactly. Think of it like this. If you make 3 copies of a program, each copy coming from the one before, as long as the media is good then the discs will be exactly the same. If even a little data were to be lost, the program would crash when the program attempted to use that data.

Am still a beginner having only bought my DVD burner about a month ago. I use DvdDecrypter and Shrink. After burning my copy I also copy the ISO file to another DVD and then use DvdDecrypter to burn another copy from it when and if I need it.

You can use your DVD burning software to make a copy of your "backup" copy.

Yes I do that sometimes but find it quicker in DeCrypter. I also forgot to give my thanks to Baldrick. Hadn't a clue how to start but downloaded his guides and they are so clear. Many thanks, Baldrick. :P

I am staying out of the rants that have been posted to this question lately.
I have one simple question:
Do I understand that the best method of making a 2nd (or, whatever) back up from a back up, is to take the data, decode, or, whatever term you prefer to an ISO file, then burn to another disc from the ISO file?

what are the best dvd+r's to burn on

[agent222]

Do you mean the best media to use, or, the best device to use?
In either case look at the list for any media, or, device you might want to buy
from the menu to the left of tthese postings.

Just curious.

Put dvdr in drive
open drive
select all
copy to new folder on HDD
burn

Wouldn't this work since there is no encryption?

I've done it this way before. Guess what... It worked.

I feel that my reply to this heavily cluttered thread will go un-noticed, but since it's a sticky, I can't justify making a new thread to cover a topic partially covered in previous pages of this thread.

I've had purchased an external Sony DVD+-R/W Model DRX-510UL for use with my laptop a while ago. I've been working off the very first 50 DVD-R spindle I bought at the same time as the drive.. very generic no name/print (now knowing they are AN30 manufacturer code thanks to DVD Decryptor which detects them as maximum 2x write speed).

I've been using it for a while to backup files or move them from my laptop while at work to my house or visa versa. I did notice that sometimes normal DVD-Roms I would go to use the DVD-R's in would begin to read it and then stop after a short term so I would plug the DVD-R drive in instead and copy the files through that instead (kinda a hastle but it's okay and works).

Recently I began looking into backing up my DVD movies since I have the drive. I started with DVD Shrink and went wild on my collection.. wild being about 10. No problems at all! I thought this was great.. then I didn't have to worry about anyone in my house dropping my DVDs anymore. Then DVD 11 came along when I went to backup The Punisher and it gave some errors. I then started working with DVD Decryptor (using DVD Shrink in combination) and got just the movie on the DVD.. this was fine for me.. the extra step was minor.

After every backup I'd go toss the DVD-R in my TIVO (but not the one that has the burner built in) which supports DVD-R's and skip through to make sure the entire movie was playable.

I finally watched one last night.. got about 1 hour and 20 minutes in and it started freezing and going again. Then about 5 minutes later it just paused, not restarting again. This would not be a big deal if it wasn't for when I finished making the copy, I had left the DVD in my reader.. walked away to try out the DVD-R and one of the kids decided to be like daddy and open the other drive and take out the DVD (original) and "play with it". Well, probably needless to say, it's heavily scratched and no longer plays in a player. I wish I had a DVD playing software on my PC to try that DVD-R in to see if it would work fine all the way through and just my TIVO did not like it, but I do not.

So on the topic of copying a copy and 1's being 1's and such.. do you think I could backup my backup to a better media?.. will it play the rest of the movie (using the DVD-R drive that burnt it as the reader)? I'm going to purchase either a Fuji spindle or another one of the highly recommended brands on this site and use my generic ones left for normal data transfer / backup.

Copying a copy of a dvd is not like copying a copy of a VHS tape, it doesnt get "watered down" after each copy. Its digital, so its the same, the same, the same over and over. Jeez people sure get worked up over this stuff.

As long as your DVD drive on your computer can read the entire disk(i.e. copy to hard drive with out any errors), you shouldn't have a problem.
But if your computer can't even read then you have an issue.

I'll give that a shot.. wasn't sure if it'd show up with errors or not.

Thanks.

i've had that problem where my backups of originols skip and freeze up but i only use hp and tdk and it only does it on some dvd players .i've been using dvd decrypter and dvd shrink and even when i re auther to just the movie some still skip

[h8sh8]

what about making a copy of a copy after using DVDxcopy to make the first copy? it seems like you can only make 2 copies?
any way around this?? ive tried with roxio and nero and it hasnt worked

try CloneDVD and AnyDVD, and do a 1:1 copy (pretty sure that's what I used - was the second copy I ever did, 1st being the dvdxcopy one, which I've never used again since). Do either "write existing data" for 'on the fly' recording (not recommended, I don't use it anymore, but it does work for me), or "Clone DVD" and make it copy temp files to hard drive before burning - it can even remove that stupid dvdxcopy screen at the start, though I can't remember how I did that sorry - though pretty sure it was just the "write existing data" thing I did - pointing to the existing files on the dvdxcopy dvd (which is all I knew how to do at the time a couple of years ago).

Each copy is identical to the last barring errors

period

where cheap media comes into play is NOT degredation of the ones and zeroes (this can not occur they are 1's and 0's nothing to degrade

what DOES degrade is the MEDIUM ITSELF the physical structure of the disc itself.

as this deteriotes those identical 1's and 0's can become difficult to impossible to EXTRACT and read.

its not generational degration its MATERIAL degradation in the dye and plastic itself.
