We're in danger of producing a horribly complicated system. An
uncompressed tar would be suitable, right? Or what do you suggest?

In Nepal we are looking to do occasional backups to USB disk.

Yes.

for i in /library/users/*; do
  setfacl -m u:apache:rx $i
  find $i/datastore-* -type f | xargs -n100 --no-run-if-empty setfactl
-m u:apache:r
  find $i/datastore-* -type d | xargs -n100 --no-run-if-empty setfactl
-m u:apache:rx
done

like that?

It may be more sensible just to add "--acls" to the "tar -c" command...
