What does your exchange 2010 DAG script look like?
Hi. We are using TDP 6.4.0 on our two Exchange 2010 Sp 2, Rollup5 servers which are members of DAG. We have 10 databases, and half are active on each server. We currently use a script on each of the servers downloaded from an IBM site back in a day...so we are reading about this single DAGNode etc but was curious...how others are doing their Exchange 2010 DAG backups. Can anyone share their scripts with us? We want to look at implementing parallel db backups as well as doing incrimentals with weekly Fulls. Any help on how to accomplish this would be helpful.
The TSM schedule kicks off the below cmd file:
REM BAckup local public folder databse
tdpexcc backup "sxmb207 dbpub" Full /logfile=backup.log
REM Run powershell script to backup passive database
PowerShell.exe -command ". 'D:\Program Files\Microsoft\Exchange Server\V14\bin\RemoteExchange.ps1'; Connect-ExchangeServer -auto; backupdag.ps1"
Here's the backup script we use from IBM's site:
#======================================================================#
# #
# IBM Tivoli Storage Manager for Mail #
# #
# Data Protection for Microsoft Exchange Server #
# #
# Script for backing up a DAG node - backupdag.ps1 #
# #
# 1. Check if server is a member of a DAG #
# 2. Get list of databases on server and thier replication staus #
# 3. Backup database if it meets one of the following: #
# - Local Healthy passive database copy #
# - Local Active copy where a healthy passive copy does not exist #
# - Local Non replicated/recovery databases #
# #
# Usage: #
# PowerShell backupdag.ps1 <log file path> #

# Version: 1.0 #
