If you are considering a backup strategy for Production Data, do consider storing the backup offsite. A geographically different location ensures that events like flooding or fire, don't destroy all the backups too!
To perform an full backup of all Bahmni Databases, one can use the following command in bahmni-environment/scripts:
Backup All DBs
sudo ./backup-all-dbs.sh -b /tmp/backup
If you want to setup an automated schedule to backup, then you can create a crontab entry to trigger this command periodically. For example:
Auto-schedule backups of DB
# Edit the crontab file of root user
crontab -u root -e
# Make entry as (for running twice a day at 2PM, and 10PM)
00 14,22 * * * sudo /Project/bahmni-environment/scripts/backup-all-dbs.sh -b /tmp/backup
crontab may fail for sudo
cron may fail silently for above command on some installations, since we use the sudo command in our scripts. To enable sudo commands to run in cron, you need to disable requiretty. Run visudo command, and comment out the line: Defaults requiretty
# Add this entry in crontab to delete files older than 15 days from /backup folder (every evening at 6 PM)
00 18 * * * /usr/bin/find /backup -type f -mtime +15 -exec /bin/rm -f {} \;
For more examples on crontab entries read this: crontab
To restore DB, use the following commands (ensure tomcat & openerp services are Stopped):
Restore Databases
###################################
# One shot restore command:
###################################
sudo ./restore-all-dbs.sh -m /backup/mysql-dump.sql.gz -p /backup/pgsql-dump.sql.gz
###################################
# Or individual restore commands:
###################################
# Unzip the backups:
gzip -d [filename.gz]
# Restore MYSQL (script is in bahmni-environment)
./scripts/restore-mysql.sh [mysql-backup-filename]
# Restore Postgres (script is in bahmni-environment)
./scripts/restore-pgsql.sh [pgsql-backup-filename]
# If pgsql restore fails because of open connections, then you can restart postgres by executing:
sudo /etc/rc.d/init.d/postgresql-9.2 stop
sudo /etc/rc.d/init.d/postgresql-9.2 start
