I made a simple working script to backup all the containers at once and send it on Linux backup server via RSYNC, here’s how to do it.
What we got:
- OpenVZ server with a lot of containers
- Linux backup server
Create file script wherever you want
touch backup.sh
Insert the code below
#!/bin/bash /bin/mkdir /home/backup/`date "+%Y%m%d"` vzdump --dumpdir /home/backup/`date "+%Y%m%d"` --compress --all sshpass -p "password" rsync -avzhe ssh /home/backup/`date "+%Y%m%d"` root@ipadress:/root/openvz-backup /bin/rm -rf find /home/backup/*
Now lets look at this script in details
/bin/mkdir /home/backup/`date “+%Y%m%d”` – creates new directory with recent day and time
vzdump –dumpdir /home/backup/`date “+%Y%m%d”` –compress –all – backing up all the containers
sshpass -p “password” rsync -avzhe ssh /home/backup/`date “+%Y%m%d”` root@ipadress:/root/openvz-backup – Here we connect to another Linux machine with ssh protocol, using password. Next with rsync we send compressed containers to backup server with already existing folder – root@ipadress:/root/openvz-backup
And after all that delete all newly created containers backup to clear up storage – /bin/rm -rf find /home/backup/*
Make it executable and run
chmod +x backup.sh
sh backup.sh
Then lets make it run daily for example. To do this, you should move it to path:
/etc/cron.daily/
So the full path will be /etc/cron.daily/backup.sh
*Optionally I added another script on the Linux backup server to control the storage
Create script clean.sh and paste the code
#!/bin/bash
find /root/openvz-backup/* -type d -ctime +7 -exec rm -rf {} \;
You can adjust the number of days here
-ctime +7
Dont forget to make it executable
chmod +x clean.sh
Add this script to cron
crontab -e
and past this to the end of file
0 1 * * * sh /root/clean.sh
In this case script will run every day at 01:00 AM
