Orin,

There is a bug in the early  5.3 client API where the diskbuffsize
parameter had a  bad default causing slow restore times.  Try setting
diskbuffsize 32 explicitly in your opt file.
I couldn't find the apar again when I just went looking for it, but I
did use this fix on some Windows R3/Oracle  clients a while back with
success and restores went from 8GB/hour to 52GB/hour.

Trying to restore Exchange database to a recovery group on same server.

The restore runs but is soooo slow it's not practical; 100 GB database
would take over 8 days.

Neither IBM nor Exchange experts can figure why it restores so slow.
Have checked parameters, etc.

Orin,

By default, Data Protection for Exchange will restore
data back into the live Exchange Server and into the
original storage group and database. The Microsoft
Exchange Server requires that the database be dismounted
for this operation. If that is not what you want,
it would help to understand what exactly you are trying to do.
Are you trying to restore in to an Exchange 2003 Recovery Storage Group?
Are you trying to restore to a different server?
Do you just want to restore the .EDB, .STM, and .LOG files
so that you can manipulate them with 3rd-party tools?

Thanks,

Del

Is there a way to redirect a TSM Data Protection for Exchange restore

to

an alternate location? When I try a restore TSM first asks to close

the

datastore.
