Hi Dell!
Jus one additional question: If I cannot set a maxsize to control the
size of a DP for SQL backup file, how can I prevent a SQL Server backup
from pinning the TSM recovery log?
One of our DP for SQL clients is backing up a very large SQL database
and it's running for several hours. Because DP for SQL is treating this
as one single transaction which is running for a long time, it's pinning
the recovery log (a show logpinned confirms this).
Thanks again for your help!
Kind regards,
Eric van Loon
