Does anybody know if there's any modern disc burning software I can point at a very large pile of files and have it split them into either ISOs or burn them onto a series of discs?
The use case here is that I back up my server onto an 8TB external hard disk. Current overall size is ~5TB of backups.
Blu-Rays would be for either cold archival of content that's "important but not really very" or for an off-site version of my main backup.
Bare internal hard disks are the cheapest per-gigabyte storage on the market right now, but the comparison isn't to those, as much as to LTO ($$$$) or RDX ($$$, but bad at archival.)
I found out that Nero does it, although Nero also installs a very large amount of crapware on the machine while doing so.
The other thing that's worth noting is that I *could* use something like winrar/7z to split the files to arbitrary files, but I'm then still responsible for making ISOs or manually burning discs.
The idea was a little bit to combine it with something like an Acronova Nimbie, at which point it's most of the way to being a "$$$" solution, but the incremental cost is still lower than, say, RDX, where a 4TB cartridge is $500. (5TB of BD-RE-DLs is around $150 on newegg in the USA, just looking.)
