Backup Hosted Engine

It’s a good idea to know this simple backup process to make sure you hosted engine can be recovered:

engine-backup --mode=backup --file=backup1 --log=backup1.log

If you are interested in automating your engine backups, here is what I do:

On Your Engine VM

• vi /etc/fstab

  192.168.1.50:/some/path/to/your/nfs/share /mnt/backups nfs rw,async,hard,intr,noexec 0 0

• mkdir /mnt/backups
• mount /mnt/backups
• mkdir /mnt/backups/engine
• vi /root/backup_my_engine.sh

  • #!/bin/bash
    
    #required for cronjob
    DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
    cd $DIR
    
    export TERM=xterm
    
    BUDATE=$(date +%Y-%m-%d-%H%M%S)
    
    engine-backup --mode=backup --scope=all --file="engine-backup${BUDATE}.bak" --log="engine-backup${BUDATE}.log"
    
    cp /root/engine-backup${BUDATE}* /mnt/backups/engine/
    rm /root/engine-backup${BUDATE}*

• chmod 700 /root/backup_my_engine.sh
• vi /etc/crontab

  1 1 * * * root /root/backup_my_engine.sh > /dev/null 2>&1

   

  That should do it. Now each day at 1:01 AM, your Engine will backup to your NFS with a date stamped backup/log file.
