To cut a long story short, I wish to compress (or tar because it's quicker)
data and to also slice the resultant files into volumes, from the
command-line (this should be a routine backup job).
The longer story: external hard-drive uses some odd filesystem which is case
insensitive. Must compress or tar data to preserve case. Must also slice to
'chunks' as the data exceeds 4 GB, which at least for the external
hard-drive, is too much.
Any advice appreciated muchly,
