Duane,

I have a similar "year end" problem.  Here's how I handle it.

I have a dedicated data path through my system consisting of a little HP
418 DLT autoloader.  I have a special "year-end" management class that
points to it.

When the end-of-year files are ready for backup, I archive them to the
primary pool defined on the little HP.  That gets me the first copy.

My copypool is a four-drive HP 4/40 DLT library.  At any given time, I have
four DLTs within it that are "filling".  I set all four to access=RO.

Then I backup the primary pool on the HP 418 to the copypool.  Because all
the filling tapes are RO, TSM will pull in a scratch tape and copy the
primary tape to it.  That gets me the second copy.

I check out both tapes, and flag both tapes as "unavailable."  That keeps
them out of the reclamation processes.

I put one copy on the shelf in our office for immediate access.  The other
copy goes to the vault.

Then I set the RO filling DLTs back to RW.  Then TSM continues its daily
activities as if nothing happened.

Hope this helps.

Subject:  Re: Point in Time Backups


 In my experience a backupset is more for server recovery than file
restoration and does not offer the ability to restore individual files,
plus
the entire server would be included on the backupset, there is no way to
exclude certain directories from it unless there was a complex method they
were backed up. (i.e. different server names for specific data types or
directories) Archiving presents a similar problem and has it's own
deficiencies when running backups and archives at the same time.

 I have been in touch with Tivoli on a number of occasions trying to figure
out a way to get a "monthend". Yes there are many ways to do it, but my
main
concern is the data already resides in the jukebox it would be ideal to be
able to copy all data for a specific server to a tape, based on a date and
time, that can be retained for "X" days, months or years and have the data
on that tape restorable on an individual file level. Two answers I have
received, "That functionality has been requested many times and is be
reviewed for a future release" or "That functionality is not what TSM was
ever intended to do and it is unlikely to be developed".

 The ability to do so would be more of a marriage between standard backups
daily, weekly, monthly and incremental always. If anybody knows of any
development in this area or has figured out a way to do this I would like
to
know. I have some engineering servers that are in the 300 - 400 GB range
and
a full backup is unfeasible, but would be ideal to have. These servers have
not been migrated from Veritas to TSM yet, specifically due to the
inability
to provide this type of support.

Just my 2 cents worth.
