Various hardware storage subsystems provide facilities which specifically
help make backups more efficient, such as Flash Copy on the IBM ESS.
This provides a means for TSM to perform backups from the snapshots,
rather than contending with the file system or database at the operating
system or database system level.  There are, of course, ramifications and
caveats.
