Epoch from EMC2 also has this problem.  I would venture to guess that ALL
backup products experience it, making it the unix systems' problem, no?
In fact, on our Auspex fileserver, epoch is so slow, that we must NFS mount
the auspex filesystems on the epoch server, and back them up that way.
This has the undesireable side-effect of updateing the files' atime :-(
Makes running an HSM product there a wasted effort.
