Performing backups

To perform a backing up of a Mayan EDMS installation, two things need to be backed up:

1. Document files

   To backup the existing data, stop the image and copy the content of the volume.

   The list of volumes can be obtained with the command:

   docker volume ls
   

   The pertinent volume to backup is mayan_app.

   Obtain the physical location (Mountpoint) of the volume with the following command:

   docker volume inspect mayan_app | grep 'Mountpoint'
   

   Create a backup copy of the location:

   sudo tar -zcvf mayan-files.tar.gz /var/lib/docker/volumes/mayan_app/_data
   

2. Database

   Use the database vendor’s respective backup procedures or utilities.

   • PostgreSQL: https://www.postgresql.org/docs/current/backup-dump.html

   • MySQL: https://dev.mysql.com/doc/refman/5.7/en/mysqldump.html

Restoring from a backup

1. Document files

   Uncompress the backup archive in the original docker volume using:

   sudo tar -xvzf mayan.tar.gz --directory /var/lib/docker/volumes/mayan_app/_data
   

2. Database

   Use the database vendor’s respective restore procedures or utilities.
