Anyhow, I'd really like to know more about how the spanning actually
works. Is it documented anywhere? http://www.amanda.org/docs and FAQ
still say that the option does not exist...
Try http://wiki.zmanda.org/index.php/Splitting_dumps_across_tapes
Yes. Thanks. That's quite helpful.
A few questions still remain, though. Like
1. Does tape splitting in any way affect the scheduling algorithm? I
mean, what if Amanda wants to dump a certain amount in order to
reach the "balanced" dump size, and only much larger DLEs are
available? Might one of those be scheduled just so that one
"split" part can be used to fill up the remaining space?
2. What happens to the holding disk file after a dump is partially
written to tape? Will Amanda keep the entire file, or just what
will be written next time around? And what if the holding disk
data is split into "chunks"?
But I'm testing a setup using "tape_splitsize" right now, so maybe I'll
find out...
