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. For the example, if you launched the container in this way:

   docker run -d --name mayan-edms --restart=always -p 80:8000 \
   -v /docker-volumes/mayan:/var/lib/mayan \
   -v /opt/scanned_files:/scanned_files mayanedms/mayanedms:s4
   

   that would be the /docker-volumes/mayan folder:

   sudo tar -zcvf backup.tar.gz /docker-volumes/mayan
   

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 backup.tar.gz -C /
   

2. Database

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