Performing a Backup of Bahmni Data on USB or External Drive

Steps to be Performed

Encrypt USB/External drive using steps mentioned in https://miguelmenendez.pro/en/articles/encrypt-usb-storage-device-linux-unified-key-setup-luks.html. Note down the password in a secret location. And don't keep a password that is shared / re-used / easy-to-guess. This is a ONE TIME activity for the drive. Encrypting the USB has the advantage that even if you lost it, you will feel a little better that it will be very difficult for someone to get to the data.
Mount the hard drive at /media/USB.

Create directories in the USB (use the mkdir command): 

# Folder struture
emr_backup
   |____ database
   |____ patient_images
   |____ document_images
   |____ uploaded-files
   |____ uploaded_results
   |____ pacs_images
       |____archive

Unlock it with the command ‘cryptsetup luksOpen LUKS0001’ with passphrase/password.
Mount the hard drive using command ‘mount /dev/mapper/LUKS0001 /media/USB'

Copy the backups as per the below steps (NOTE:rsync is a command line program for doing delta updates / copy. Read more about it here):  /media/USB/emr_backup/database/ # Backup image files - patient images, document images, pacs images, uploaded_results, uploaded-files (depending on what features of Bahmni you are using) rsync -rh --progress -i --itemize-changes --update /home/bahmni/patient_images /media/USB/emr_backup/patient_images/../ rsync -rh --progress -i --itemize-changes --update /home/bahmni/document_images /media/USB/emr_backup/document_images/../ rsync -rh --progress -i --itemize-changes --update /home/bahmni/uploaded-files /media/USB/emr_backup/uploaded-files/../ rsync -rh --progress -i --itemize-changes --update /home/bahmni/uploaded_results /media/USB/emr_backup/uploaded_results/../ rsync -rh --progress -i --itemize-changes --update /var/lib/bahmni/dcm4chee-2.18.1-psql/server/default/archive /media/USB/emr_backup/pacs_images/archive/../]]>

# Take database backup using the DB backup scripts for MySQL and PostGreSQL DBs


cd ~/bahmni-environment/scripts
./backup-mysql.sh password
./backup-psql.sh
cp /backup/<two newly created files> /media/USB/emr_backup/database/


# Backup image files - patient images, document images, pacs images, uploaded_results, uploaded-files (depending on what features of Bahmni you are using) 


rsync -rh --progress -i --itemize-changes --update /home/bahmni/patient_images /media/USB/emr_backup/patient_images/../
rsync -rh --progress -i --itemize-changes --update /home/bahmni/document_images /media/USB/emr_backup/document_images/../
rsync -rh --progress -i --itemize-changes --update /home/bahmni/uploaded-files /media/USB/emr_backup/uploaded-files/../
rsync -rh --progress -i --itemize-changes --update /home/bahmni/uploaded_results /media/USB/emr_backup/uploaded_results/../
rsync -rh --progress -i --itemize-changes --update /var/lib/bahmni/dcm4chee-2.18.1-psql/server/default/archive /media/USB/emr_backup/pacs_images/archive/../

Umount the disk using ‘umount /media/USB'.
Lock the drive again with ‘cryptsetup luksClose LUKS0001'.
Disconnect the hard drive and keep it in a safe, secure and remote place from the production environment.
