DB Backup using bahmni command line tool (available from v0.81 onwards)

'bahmni' command line tool will be available in the machine where we install the 'bahmni-installer' rpm -Install Bahmni on CentOS#Step2:PerformthefollowingstepstoinstalltheRPMs

To take db-backup, following command has to be executed:

bahmni -i local db-backup

If custom inventory file is setup, following command has to be executed:

bahmni -i <inventory_file_name> db-backup

The command will take the backup of each database into a seperate file in the machine where the databases are present at file location /db-backup as below:

Optionally, it would also allow you to copy the backup to the machine from where the command is executed by shooting the following question:

Do you want to copy db backup to local machine in /db-backup directory? y/N: y

This would be useful in multi-machine setup where databases are present at different location. When all databases are present in the same machine from which command is executed, 'N' can be given as the answer to the above question.

DB Restore using bahmni command line tool (available from v0.81 onwards)

To restore the database, `db-restore` command from bahmni command line tool can be used. The command can restore only one database at a time and it will drop the database if already present and then restore the specified dump file.

bahmni -db <database_name> -path <zipped_sql_file_path> db-restore
 
# If custom inventory file is present
bahmni -i <inventory_file_name> -db <database_name> -path <zipped_sql_file_path> db-restore


#Examples:
bahmni -i jss -db openmrs -path /db-backup/openmrs_dump_20160525-155357.sql.gz db-restore
bahmni -i jss -db clinlims path /db-backup/clinlims_dump_20160525-155359.sql.gz db-restore

Automated db-backup

Download the backup script 

wget  https://gist.githubusercontent.com/sravanthi17/27e239bfe1e0773d982f7b715fa582b3/raw/178ccc164693d9c134dd3324387ce38b3dd7783b/db-backup.sh {path_to_save_script}

Create a crontab

If you want to setup an automated schedule to backup, then you can create a crontab entry to trigger this command periodically. For example:

{path_to_save_script}/backup.sh 

00 14,22 * * * sudo {path_to_save_script}/backup.sh 
 
# eg. 00 14,22 * * * sudo {path_to_save_script}/backup.sh 
# eg. 00 14,22 * * * sudo {path_to_save_script}/backup.sh 

# Add this entry in crontab to delete files older than 15 days from /db-backup folder (every evening at 6 PM)
00 18 * * * /usr/bin/find /db-backup -type f -mtime +15 -exec /bin/rm -f {} \;
