Today on UNIX servers yes.  But on NT no you do not need to quiesce
the file system (using TDP for Workgroups and eventually TDP for
Servers when that product ships).

On UNIX eventually one will not need to unmount the file system either.
Tivoli's statement of direction is to produce an online file
system level backup.  This will prevent the headache of stopping all
your production apps on a routine basis to backup the file systems
and raw logical volumes.
