In my last article , I described you how to take backup and restore OpenERP database using Openerp GUI or web-interface method method. Now, In this article , I`ll describe you how to take backup of your OpenERP database automatically and regularly too after certain time of period, using cron on linux.
1) Create 2 directories, one for placing the backup script (/var/scripts) and other for placing your database dump files (/var/pgdump).
NOTE – both directories should be owned by user = root
2) Create a script file as – /var/scripts/dump_db.sh, set permission as 700, owned by user = root and meant to run as root. I`ll set a cron job. The content of this script will be -
#!/bin/bash
#fixed parameters:
date=$(date +"%Y-%m-%d_%H:%M:%S")
db='name_of_the_db_u_want_to_take_backup'
backup_path="/var/pgdump"
filename="$backup_path/${db}_$date"
# Stop OpenERP Server
/etc/init.d/openerp-server stop
# Taking Dump of selected DB
sudo -H -u postgres bash -c "pg_dump --format=c --no-owner $db>$filename"
# Start OpenERP Server
/etc/init.d/openerp-server start
exit 0
NOTE: starting/stopping openerp server is needed only when the database is heavy
You can test whether this script is working or not by manually running it, like this
/var/scripts/./dump_db.sh
3) If everything goes correct , create a cron to run this script regularly after certain time of period -
sudo crontab -e # add this line 0 */12 * * * /var/scripts/dump_db.sh # this would run after every 12 hours i.e twice a day
4) In order to restore using these dump file we can use Openerp GUI.
5) Remove old dump files ,
- create another script (deletes backups which are older than 30 days) as
/var/scripts/rm_db.sh
#!/bin/bash
sudo find /var/pgdump/* -mtime +30 -exec rm {} \;
exit 0
- add this to cron as -
sudo crontab -e # add this line 5 8 * * 6 /var/scripts/rm_db.sh # this would run 8:05 every saturday
That`s it !!!
I hope it will help someone.
