Spinning optical media has soooo many advantages:
* Easy to label.
* Easy and dense to store.
* Read only: No urge to cannibalize backups.
* Cheap as hell.
* Lasts decades if kept in a box in air conditioned room.
* Boots more reliably than thumb drives.
* More difficult to lose or confuse with others.
Thumb drives are nice for temporary storage, and with USB3 maybe even
overflow storage, but AFAIK they can't be put in a read-only state, so
if you're booting from them, you're never really sure what's on them. I
dare anyone to make a virus to infect an already recorded and finished
SD cards (not even speaking of micro-SD) have a higher density and
can be put in readonly mode. They are certainly more expensive, but
CDs and DVDs have several different standards and most drives
cannot read all of them. I've also experienced that CDs written on a
drive couldn't be read from another one and vice-versa. CDs and DVDs are
OK for archiving data for a few years; I don't trust them for longer.
For what concerns an installer, a few weeks is longer than what you
need and there's nothing precious. Better use an USB stick or an SD card
if you can download the content from the Internet.
I think CDs are mostly good for usages in which it matters that the
support is inexpensive, like commercial videos. But also, of course,
when nothing else is available.
