About deduplication, Mark Stapleton said:
It's highly overrated with TSM, since TSM doesn't do absolute (full)
backups unless such are forced.

Up until about 6 months ago (when .pst files were exiled), we were

Prior to implementing subfiles (which we limited to .pst and Access

Hello,
I don't really understand from the docs if there might be a file
ownership conflict between a dsmc setup for an Authorized-User and a
non Authorized-User use of archive function.
The Security Guide says :
Non-authorized users can retrieve objects that they archived, because

The IBM quote describes what happens in the general case with
Archive: that the Owner is assigned as the invoker of the Archive
command - rather than the owner as seen in OS file system
attributes. (This differs from Backup, where the assigned Owner is

TSM - actually adsm 1.1 - some people, mostly managers, have
asked how many copies of any file, for example winword.exe, are

Thanks Richard for your reply and your great work on QuickFacts!
Anyway, I would mitigate your answer on two points :
- is your reply also correct if dsmc is setuid-ed for a non superuser ?
- For backup, solely an authorized user or a root user can backup files
while keeping ownership of the
Most large organizations I work with have a Standard build for their
systems - the OS, applications, etc - so they only need to backup data (we
do that internally in IBM as well). Minimizes what needs to be backed up,
and makes deploying systems MUCH easier (1 DVD, just over an hour, all
set).

On one host, I recently upgraded the TSM client from 5.4.0.0 to

files rather than just changes. Has anyone else seen this behavior?
Is a simple client version switch enough to trigger a full backup?

A variety of such full backup mysteries have appeared in ADSM-L. My
suspicion is that the cause involves the Extended Attributes support

Must correct and add some information...if you'll use SKIPACL, there's no
need for the SKIPACLUP (one overrides the other).
- With SKIPACL, no ACL and extended attribute will be backuped or restored;

Many VTL/deduplication venders pitch a 20:1 or 50:1 ratio, TSM you might
see 10:1 or 15:1 because of the progressive backup method. Always
question the TSM trials with a venders deduplication claims.

When dsmserv starts, it looks in dsmserv.opt.
Dsmserv.opt has the location of the devconfig and volhist.
If the location isn't correct, you'll need to fix it before you run the
DSMSERV RESTORE DB.
dsmserv looks in the volhist for the name and devclass of the DB backup

Does TSM have the ability to make a mirror copy of a client's data in a
SAN environment? For instance can it copy from, say a DS8000 to iSCSI
storage (both on a SAN), such that we could just disconnect the client
from the DS8000 and point it to the iSCSI storage. Then, upon reboot,

We did a financial analysis of dedpue with TSM vs. just simply buying
more disks, and the more disks solution came in cheaper. Plus a huge
advantage in simplicity. Those dedupe appliances are expensive! Their
sales pitch is that they can compress 20:1, so they charge 12 times as
much money. But
