MAN / AER postgres db alternate storage
We have a Man AER node...... We haven't used it yet...
I would like to setup a alt location to send the postgres DB exports too... And I was thinking. Maybe we can use
the Avamar Grid that it will backup from...
Has anyone done this? Is this do-a-able?
Thanks...

Joe,
AER node is running an external avamar agent activated on the external grid so you could use similar previous scripting and replace scp command by avtar command and backup snapshot folder on the external server.

Joe,
DR exports can be sent to another machine using scp for example. Procedure steps are documented on this KB:
https://support.emc.com/kb/192102
If you don't have access these are the steps:
• In order to be able to successfully create an AER DR copy we need first to have at least one tape with space, labelled on the Default pool
• By default the AER DR copy needs to be run manually using the command below but many customers ask support to configure this to run auto
/opt/EMC/avamarer/bin/avamar-er-dr --export --pass=
•In order to run this command automatically we can use the AER internal Avamar cron
crontab –e
•And add a line at the end of the cron tab (with the time and frequency we want it to run) with something like the following as an example
34 12 * * * /root/AERdisasterrecovery.sh
•Where “AERdisasterrecovery.sh” is the following script which runs the DR command and does a scp of the snapshot file to an external server in order to keep the DR snapshots safe in the case if we lose the AER server
#!/bin/bash
PATH=/usr/local/avamar/bin:/sbin:/usr/sbin:/usr/local/avamar/bin:/bin:/usr/bin:/sbin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/usr/local/apache/bin:/usr/local/ssl/bin:/opt/dell/srvadmin/bin:/opt/dell/srvadmin/sbin
export PATH
SNAPSHOTDIR=/tmp/ER-DR-SNAPSHOT
#create DR copy
/opt/EMC/avamarer/bin/avamar-er-dr --export --pass=
#copies the DR snapshot outside the AER server
File=`ls -latr /opt/EMC/snapshot | grep -e avamar-er-dr-1.1.0-01-Snapshot.zip | tail -1 | awk '{print $9}'`
echo $File
cp /opt/EMC/snapshot/$File $SNAPSHOTDIR
scp $SNAPSHOTDIR/$File root@ :$SNAPSHOTDIR
•This way we can automatically create snapshots of the AER configuration outside the server which will allow us to fully recover the server in the case of loss
* note that for a fully server recovery we also need the Networker bootstrap which is also generated with the same command but is saved on the Default tape pool

Is there a process to setup a trusted method of sending the DB exports to a Avamar Grid?

You are right, it is not a normal plugin since it is the DTO export and imports plugins but avtar binary is similar to any avtar running on any Linux system and it can be used to backup DR image via command line as I suggested.
