Thanks Alex......
I'm learning, and you (all) have been very helpful!
The new/modified vocabulary seems to be the toughest hurdle.
      Why can we still call cats, cats?

Hi, Ken.

Actually, Ken, the expiration I'm talking about is when something is deleted
off of the client server, not the server side "expire inventory" process, so
it really shouldn't be affected by versions/retentions in your copygroups.
During a full incremental, TSM will "expire" a deleted file and set it to
Inactive in the TSM server.

You can see this by creating a file, say, /home/me/mytestfile.
dsmc inc /home/me/\*
rm /home/me/mytestfile
dsmc inc -incrbydate /home/me/\*

It won't Expire mytestfile.

dsmc inc /home/me/\*

It will Expire mytestfile, and it'll say "number of objects expired: 1"
This will also be posted to your TSM server's log.  So you should be able to
test it immediately after your regularly scheduled backup.

Alex,

Thanks.
That works too!  Or as you might say "maybe/probably/for now".  If I start
modifying upward, my "versions" and "retain" values, deletion may not happen
for quite a while.

How about this.  Check the session end summaries for each node, the one that
says, "Number of objects expired." (ANE4970I)  If it's not zero, then you
know it's a full incremental that is expiring objects.  If it is zero, well,
that doesn't tell you too much, but you can watch it for a while.  There
aren't too many servers where no one deletes anything over a period of
weeks.  If it is always zero, delete or rename a file on that server.  If
the next backup says expired=0, then there you go.

Hi Ken,

There is no way (at least none that comes to mind at this time) from an
administrative standpoint to determine this.

Partial incremental is also known as "incremental by date". To use this
kind of incremental backup, the -incrbydate option would have to be passed
to the client. For example:

   dsmc incremental -incrbydate

You an also pass it through a schedule defined on the server, like this:

   define schedule standard mysched options="-incrbydate" ....

(If you have -incrbydate in the schedule definition, then you would know
it).

When a regular incremental backup is run, the client output will show when
it is starting the backup for each volume like this:

   Incremental backup of volume 'C:'

When incremental by date ("partial") is run, the message will look like
this:

   Incremental by Date of volume 'C:'

Regards,

Andy

Hi fellow listers,

So here I am, "Reading the Fine Manual", and it sez; an Incremental Backup
can either be "full" or "partial"..
How can I tell if my backup(s) are requesting a "full" or "partial"
backup?
