Backup Domino on Linux using VDR or Veeam

1. Install VMware-Tools (I think it should be installed but unlucky still a lots out there do not know how to install on Linux)
2. Create a script /usr/sbin/pre-freeze-script

#!/bin/bash

# Just a log with date, you can remove it
echo $(date) >> /var/log/snapshot.log

# Assume Domino Service is installded and started by user "domino", we drop all connection and flush all database cache
/bin/su - domino -c "cd /local/notesdata/;/opt/ibm/lotus/bin/server -c \"drop all\";/opt/ibm/lotus/bin/server -c \"dbcache flush\""


# Some forks saying we should do a sync before backup, run it with no harm...

/bin/sync

3. chmod 755 /usr/sbin/pre-freeze-script


4. In VMware vSphere, take a snapshot of your Domino Server, uncheck "Snapshot the virtual machine's memory" as it will not run the script is memory is taken and check "Quiesce guest file system".


Check if /var/log/snapshot.log has date recorded and better connect your Domino Console and see if the connection has been dropped when taking snapshot (to prove the script has been run correctly).

Remove logwatch mail on RHEL with Domino

If you don't really care and want to use logwatch, easiest way, remove /etc/cron.daily/0logwatch
OR
If you care about logwatch, go  /usr/share/logwatch/default.conf/logwatch.conf and config those mail settings
