Cisco SD-WAN Backup

[RS19]

Hi

Is there any mechanism by which we can take the backup of all the configurations from vManage such as a centralized backup which can be used in case of any restoration during any trouble or issue.

you can take backup from vManage configuration DB through below CLI:

>> request nms configuration-db

NOTE: above CLI will take a local backup from the configuration database. So you should run a separate scheduled script to transfer it to an external storage - central backup server or whatever you have inside your network

use below url for details: 

https://sdwan-docs.cisco.com/Product_Documentation/Command_Reference/Operational_Commands/request_nms_configuration-db

And if you need to restore vManage from a catastrophic crash, you can use below guideline.

Unfortunately that first link doesn't work anymore.  I found the command to backup the database locally, but like you said I want to transfer the DB file (scp) to a different server in case of crash.

I found an upload command but the Cisco documentation states it doesn't work for vmanage??

Anyone know how to SCP the database file to remove server?

thanks

The correct first link is this: https://www.cisco.com/c/en/us/td/docs/routers/sdwan/command/sdwan-cr-book/operational-cmd.html#wp3537591161

You can save the configuration database at a location on vmanage (such as the home folder of the admin user, for example) and then retrieve it via SCP.

Anyone know how to script this to backup the DB periodically?  You would think this would be a built in feature.

We use the following script to create a backup from remote, and then copy it (pull) to our backup server via SCP (sorry tabs got lost in the copy process here):

function run_configdb_backup() {
        export VMANAGE_HOST=$1
        export VMANAGE_USER=$2
        DATE=`date +"%Y%m%d-%H%M"`

        # cloud hosted instances do not support automatic daily backups, so we need to create this manually first.
        # TAC SR 694690210 
        if [[ $1 == *viptela.net ]]
        then
                # delete pre-existent file
                echo "request execute rm -f /opt/data/backup/sastre-backup.tar.gz" | ssh -i ~/.ssh/id_rsa ${VMANAGE_USER}@${VMANAGE_HOST}
                
                # create backup
                echo "request nms configuration-db backup path /opt/data/backup/sastre-backup" | ssh -i ~/.ssh/id_rsa ${VMANAGE_USER}@${VMANAGE_HOST}
                
                # SCP file by using id_rsa SSH private key
                scp -q -i ~/.ssh/id_rsa ${VMANAGE_USER}@${VMANAGE_HOST}:/opt/data/backup/sastre-backup.tar.gz ${CONFIGDB_BACKUP_DIR}/${VMANAGE_HOST}/configdb-${DATE}.tar.gz
        else
                # SCP file by using id_rsa SSH private key
                scp -q -i ~/.ssh/id_rsa ${VMANAGE_USER}@${VMANAGE_HOST}:/opt/data/backup/daily/configdb-daily.tar.gz ${CONFIGDB_BACKUP_DIR}/${VMANAGE_HOST}/configdb-${DATE}.tar.gz
        fi
