As I mentioned in my previous post, before creating a link BackupPC
(and also my routines too btw) check to see if HardLinkMax is exceeded
and if so then the pool element is duplicated (actually moved
typically) and new elements are linked to it. This just adds an
element to the md5sum chain. This all happens automatically and
sensibly in BackupPC.
