I have created ISOs on the CLI years ago, it is not that difficult. I can help with that part. The dificulty is adjusting the size. I have no idea how to split and span to several DVDs.
As far as I can make out there seems to be a few different approaches to all this. On the one hand there are the 'snapshot management' types such as dev-dup and backintime that need to maintain a database and really are a dis-to-disk(-to-offline) so that the snapshots are easily recoverable Then there are the ones that don't keep the database, or at best rely one the label on the DVD, written or electronic, and are probably event drive, such as a completion of a particular project and hence archiving all its working papers and reports. There *may* be some way to logically organise this archiving, for example 'monthly' as the project progresses. That takes the pressure off the 'spanning multiple DVDs' issue. They don't need the database of the individual files in the same way. Once you do get into spanning multiple DVDs then you get into two issues. The decision of where to split goes hand-in-hand with the decision of what files to put on each DVD most efficiently (or optimally) -- the 'packing problem' which is at the very least NP-hard and quite probably NP-complete https://en.wikipedia.org/wiki/Bin_packing_problem https://en.wikipedia.org/wiki/Knapsack_problem#Multiple_knapsack_problem https://en.wikipedia.org/wiki/Packing_problems The second issue is that you need a global index of what is on each DVD. Either you have to pre-compute the "bin packing" and ahead of time and record the index on each DVD as a 'header' that says 'it's here or its on the other one' or the index has to be external. I can't say I like any of this. What we need is a K3B that is super-super smart, since I really don't fancy trying to all this with shell script.
What I envison is going through this list one by one:
