BRMS can cut down on the clock time. I do not think you can use parralel
saves
on the SAVSYS, but you can on the NONSYS. To really save time, you can save
Domino databases while active. We have 6 Domino Servers per system, and
back
them up through three seperate control groups, all running concurrently. We
save servers A,B,E,F in one control group, Server C, in another, and Server
D
in the third control group. All these saves are done with Domino active,
saves
start at 6pm, and are finished by midnite. Single threading, it would run
till
past 6am. It is possible to further decrease time by using the incremental
save
for Domino.

We use 3590E drives with the K series tapes, 6 drives in one 3494 library.
No
operator intervention required during the saves, all tape movement out of
the
3494 is handled during morning shift.
