Although you can force "full" backups I recommend you only do incremental
backups. The TSM server will only backup what has changed since it's last
backup, yet have a complete set of data available for restores. There is
no need to backup ALL your data every time.

I think what you wrote above is not exactly correct. If these "weekly"
backups need to be scattered, it would be througout the week, not month.
Otherwise these are monthly backups not weekly.
You could just set 3 groups and distribute your clients amongst these 3
groups. I recommend against going crazy and creating 7 events. TSM has a
number of facilities to control how many processes and when they are run.
For instance you can specify you only want up to 20 processes running.
Your 3 sessions will all be set to the same time and you can specify a
window when the jobs can start of 4 hours. TSM does some level of
randomization so not all jobs actually start at the same time, then as the
different times are trigered only as many jobs as the max you defined will
start. The other jobs will wait until jobs complete as long as the window
specified has not elapsed.

There are 3 modes of backup. Look at the online help when defining the
backup types. I don't recall the names but basically you can set them to
not backup open files (I think name of one is static), try to backup open
files at the end of the backup run and retry up to a number of retries
which you can specify and lastly you can tell TSM to backup the files
regardless of whether they are open.

For starters I don't advise you do 7 weekly schedules. I think 2 or 3 is
probably enough. You could also try just doing it all at once. How much of
the data on the local machines changes? If it is just a few megs daily
then you could even do them all in one night.
The only issue with having 7 schedules is that it becomes more difficult
to maintain. Same for the monthly. You could probably just do 2 or 3
schedules and put all clients in them.

That is a parameter you define when doing the backup.
I highly recommend you "play" with the different options and parameters
when setting up the clients and schedules. Although you can get a lot of
god advice from this list, but nothing will be as good as just doing some
work, trying different settings and determining what works for you.
