Re: [ADSM-L] exchange 2010

Hi Remco,

The PREFERDAGPASSIVE tells DP/Exchange to only back up an active database
if there
are no current healthy passive copies of the database. If no healthy
passive copy
is available, the backup is made from the active copy.

Most of the DAG backup best practices and methodology is in the Exchange
book
under "Database Availability Group (DAG) backups":


http://www-01.ibm.com/support/knowledgecenter/SSTG2D_7.1.1/com.ibm.itsm.mail.exc.doc/c_dpfcm_bup_replica_exc.html?lang=en


The key to "load balance" when setting up the scheduled backup script is
to have
a separate invocation of each database.

For example:

   TDPEXCC BACKUP DB1 FULL /MINIMUMBACKUPINTERVAL=720 /PREFERDAGPASSIVE
   TDPEXCC BACKUP DB2 FULL /MINIMUMBACKUPINTERVAL=720 /PREFERDAGPASSIVE
   TDPEXCC BACKUP DB3 FULL /MINIMUMBACKUPINTERVAL=720 /PREFERDAGPASSIVE
   TDPEXCC BACKUP DB4 FULL /MINIMUMBACKUPINTERVAL=720 /PREFERDAGPASSIVE
   TDPEXCC BACKUP DB5 FULL /MINIMUMBACKUPINTERVAL=720 /PREFERDAGPASSIVE

Then, run this command from each of the Exchange servers at or about the
same time.
