Christian,
As I said before, switching management classes is not the correct
solution. Remember, when you change a management class
Saying you need full backups on a weekly, monthly, and annual basis
doesn't really answer the question as to *why* you need them. It is
important to understand *why* you need them so that an appropriate
solution can be implemented.
In general, most backup requirements (actually, "restore requirements" is
a better way to think of them) can fall into two general categories:
(a) Need to get a file back if it is inadvertently deleted, updated
incorrectly, corrupted, etc. This is, generally speaking, a short-term
retention requirement. For example, you might have a requirement to be
able to restore files from backups made up to two weeks ago.
(b) Need to get a file back for audit purposes, usually required by the
government or other regulatory agencies. This is, again generally
speaking, a long-term retention requirement. For example, you might need
to perform annual full backups and keep the backups for 5 years.
The design behind TSM sees (a) and (b) as being two separate and distinct
requirements. The TSM "backup/restore" functions are for requirement (a)
and the "archive/retrieve" functions are for requirement (b).
Some points to consider:
- You perform daily incremental backups. These are clearly in support of
requirement (a).
- You say you need weekly full backups. What is the intended purpose of
these backups? For how long do you wish to keep them? If these are for
short-term retention, then I would question the need for doing this. The
active backup copies that TSM maintains reflect the state of the machine
as it was during the last incremental backup operation (with some
variances, depending on how much file change activity there was *during*
the course of the backup). So the question is, does the need for weekly
full backups fall into requirement (a) or (b)? If (a), then what benefit
do you expect to gain from performing weekly full backups?
With that said, if the need for weekly full backups is part of requirement
(a), and if you insist on doing them, then the easiest thing to do is as
Zlatko suggested in another response on this thread: Create Admin
schedules to change your backup copygroup MODE setting from MODIFIED to
ABSOLUTE when you want to run the full backups, and then to change the
MODE back to MODIFIED when you want to revert to incremental backups. You
can go to www.ibm.com and search for article 1083039, which gives more
information on this subject. You will need to be registered with the IBM
web site to see view this article.
If the need for weekly full backups is part of requirement (b), then you
really need to look at the archive operations. Similarly, monthly and
annual full backup requirements are almost certainly more of an archive
requirement than a backup requirement.
In the case of archive, you need to pursue whatever problems you may be
experiencing during the archive operation. If the operations are
completing with return codes other than 0, you need to take a closer look
at the client dsmsched.log and dsmerror.log files to figure out what is
going on.
For more discussion on archive versus backup, you can search the ADSM-L
archives at http://search.adsm.org. Have a look at
http://msgs.adsm.org/cgi-bin/get/adsm0104/108/1.html (post by Kelly Lipp
from the ADSM-L archives) interesting reading. That post contains a link
to a white paper that Kelly wrote that you may find informative.

Subject: Re: Basic Question
Thanks Andrew for your answers ...
The archives schedules failed with RC=12 or RC=04 ... and in summary the
files failed is 0. The Version of my TSM Server for NT is 4.2.3.2 and i
have
clients NT 3.1.0.7, NT 5.1, NT 5.1.5.15. I couldn't find the reason.
I need the full backups for weekly, monthly and annually backups and my
intention is replace de archives backups for Full backups in with copy
mode
ABSOLUTE. But how do to switch for different Management Classes ???
