Steven,
I have a PowerShell script that does what you are asking, in terms of different
databases on different days (in our case, we round-robin our full backups
across the week). It also allows for multi-threaded backups, although the way
VSS works, the databases each need to be on separate vols for it to work. If
you are interested in seeing the script, send me a private email. If nothing
else, it might point you in the direction you want to go.

Subject: [ADSM-L] Exchange Backup return codes
Hi All
I'm setting up TSM for exchange (7.1.0.1) with Exchange 2013. Servers are
6.2.6.0 on AIX 7.1
I have 2 DAGs, 8 databases per DAG and each DAG is comprised of two windows
boxes.
I thought I'd use the new facilities so I run
tdpexcc backup * full /preferdagpassive /minimumbackupinterval=60
And do this 30 minutes apart on each of the nodes in the DAG.
The issue is that I get RC 418 or 1848 (that may be wrong I'm sending this from
home) because a database is excluded from backup by either the
/preferdagpassive or /minimumbackupinterval switches. This indicates an error
where I think it should not, since I asked for this behaviour.
As batch commands are quite difficult to program, I looked at the powershell
versions of the backup command. If I read it right you'll get an array of
error objects for any errors encountered, but you'd have to process the whole
array to see which were real errors and which were not. Powershell is not yet a
strength.
Has anyone come up with a solution they'd be willing to share? Any ideas?
While I have your attention, there are two more issues.
I'd like to backup different databases on different days, programmatically
determined, so I can run the same script and have it produce different results.
In order to do that I would need to interrogate exchange and filter on mailbox
name, since the dbname supplied to the backup command is either * or something
specific, not accpting wildcards. Any pointers on what I have to do within
powershell to access the exchange cmdlets?
Finally, I'd like to turn on client compression. The manual says to do this
at the VSS provider, i.e. the windows BA client node. It does not seem to be
working for me. I'd also like to have include.compression statements that are
specific to exchange so that normal OS files are not compressed, and there is
not a lot of guidance on that. Has anyone cracked that problem?
Thanks
Steve
