This scheme uses a folder in your home directory named BackupRepository which contains sub folders [Sun, Mon, Tue, etc.] This should be run nightly via a cron job to tar the openemr directory, do a mysqldump and move both files to that day’s folder. Rsync is used to sync them to another location because its much faster than copying, which moves the entire file. Rsync applies only what has been changed in the source files to the destination files. HINT: After the first run, copy both files into all the daily folders, this way Rsync only has to send the changes instead of the entire file. This scheme keeps a weeks worth of backups at your disposal before overwriting them.
INSTRUCTIONS
Create a folder named BackupRepository in your home directory. Inside that folder you need to
create daily folders with 3 letter abrv. as shown using; mkdir /home/username/BackupRepository/Sun
Continue creating the daily folders using the “up arrow” to recall and edit the previous command.
The first letter of the daily folder must be capitalized, as in Sun, Mon, Tue, etc.
To mount your external drive assuming it is not partioned AND on a usb2 port (usb3 doesn’t play nice)
First create a directory in the media folder using; sudo mkdir /media/xdrive
Next identify which device it is by using; lsblk (we’ll assume its sdb1 as used in the next command)
Then mount it with; sudo mount /dev/sdb1 /media/xdrive/
Check access using; cd /media/xdrive
Followed by; ls -al to list files and directories in it.
Create the BackupRepository directory using; sudo mkdir /media/xdrive/BackupRepository
As before, create sub-folders with 3 letter abrv. using; sudo mkdir /media/xdrive/BackupRepository/Sun
To Restore OpenEMR from a backup;
First restore the SQL Dump using:
sudo mysql -uroot -p[password] openemr < /media/xdrive/[DAY]/mysql_backup.sql
Next Delete or rename the /var/www/openemr directory
Then restore the openemr directory using:
sudo tar xf /media/xdrive/[DAY]/openemr_backup.tar -C /var/www
