Trying to make a data backup onto a DVD

My buddy owns an auto garage and has a program that he can look up GM car parts from DVD's. He has (2) areas that his mechanics can look this info up, but they are not near eachother. He wants to backup these DVD's to protect the originals and use on both PC's. We have tried Nero Express which didn't work, it pulled the info off the DVD fine but when we put the blank DVD in to burn it - a message came up "not enough space on this disk"......Does anyone have any suggestions on how to do this or a better program to use. Any insight would be greatly appreciated, and we thank you in advance for your help.

What kind of DVD disc is the data on? If it's on a regular DVD-R then Nero should copy it directly since it's size will be less than 4.38Gb.

Hiya,

Your buddy would be better served in this fashion:

1 - download and install Daemon Tools on BOTH machines:
http://www.daemon-tools.cc/portal/portal.php

2 - create an ISO image of the DVD (use Nero to create an image on hard drive)

3 - load the ISO image (.nrg if created by Nero) created into Daemon Tools on each machine.

Bingo!!

BENEFITS:

1 - No DVD required on each machine.

2 - No DVD to be lost/stolen/scratched/damaged etc (it can be locked in a safe).

3 - FAST access to the virtual DVD (hard drive speed is quicker that DVD speed).

4 - If the two machines are networked, only one ISO image needs to be maintained/upgraded when needed (copy to required machine) - linking to an ISO over a network can be slow depending on access patterns etc, best just copy the ISO over.

5 - COST: just hard drive space and a little time in creating the ISO/installing Daemon Tools etc.

DRAWBACKS:
Requires a LITTLE thought and effort initially.
Anyone other than the laziest can do it.

P.S. IF the program on the DVD requires a "Dongle" to run, it will still need a "Dongle" when using the Daemon Tools image (it only creates a virtual DVD drive, it does not crack program security)

Hope this helps...

Hiya,

from the other thread that you posted to (an honest mistake):

Quote:
The only problem with putting the info on the hard drive is that there is 10 DVD's of info. I don't think his hard drive is big enough to hold that much info. Sorry I didn't mention that earlier, is there a way to make mobile copies?.......I just found out that one of his DVD's is 6.74 gb in size. OK, now what? are larger capacity DVD's available, or can we compress the originals onto a 4.7 gb DVD?? Thank you again for your help.

Not sure what you mean by "mobile copies".

Recordable DVDs of a capacity greater than 4.7GB are extremely rare and exceedingly expensive (never mind the cost of the drive - thousands of dollars at the moment).

There is no way to compress the DVD contents and still have them readable by the original program (these are DATA DVDs we are discussing here, not Video DVDs which are a different animal and CAN be compressed).

The options available are:

1 - upgrade/add hard drive to hold the images (10 DVDs @ 6.74 GB == 67GB approx, that is WORST case, an 80GB drive costs little nowadays), one for each machine...

2 - store the images on the largest available space and share them over the network (cheaper but slower and more work for the machine that is storing the images)

Have Fun....

If the data on the disc is in individual file format then you can rip the disc to your hard drive and then select the files manually from the folder to go on to two seperate discs.

Discmania:

It is a 10 DVD set of Data Disks for a particular program.

The program probably expects certain files to be on certain disks, and probably checks that too (most expensive, vertical market software with large datasets like that do so, it is a standard anti-copying trick that is dirt cheap to implement and an absolute PAIN to try and crack).

So how would splitting filesets over multiple disks help, as the program would notice that the files were missing from the expected disk (could end up with a MASSIVE amount of disk swapping as the program requests the CORRECT disk).

The virtual DVD drive/ISO/network is by far the easiest, cheapest, quickest and most efficient method.

Just my thoughts on the matter!!!
