Backing up large files to DVD

[akadmon]

Can someone point me to an app that is able to split and burn files exceeding the the capacity of a single DVD, and restore/rejoin the mutilple parts back to a single files?

Like Toast? Or do you prefer something like the cheaper Disco? (Or can Disco "just" split multiple small files among several discs and not just one large file?)

I Toast 8 any better at this than Toast 7?

I have no idea. Haven't tried since upgrading to 8. Did it once with Toast 7, though, and that worked just fine...

There is a built-in way if you don't mind using Terminal and you don't have to pay for Toast:

From the user fds at macworld forums:

" Apple's dmg format also provides native support for spanning multiple segments, they just don't provide a GUI way to create them.

for example, if you made a big dmg image, you can use:

Code:

hdiutil segment "input file name.dmg" -segmentSize 4400m -o "segmented output"


to have it split into parts no larger than 4400 MB.

When you want to later use this segmented image, you have to copy all the segments into the same folder and simply double-click on the first one. "

BTW, I noticed that I have more disk burning problems if I go above 4.3G.

You might also just want to consider a parchive approach, to make sure you can recover if one of the DVDs goes bad or just missing. Basically RAID-5 for separable chunks.
