Backup and restore

We recommend updating your database and uploaded files regularly. It is also highly recommended to do a database backup before you upgrade to a newer Corteza version.

You can define a cron job that backups your data to some external storage.

Backup the database

We recommend the use of mysqldump tool. It’s builtin to the db container (percona:8.0 image).

If you want to use a different tool to create your backup, you will need to connect to the container or publish MySQL ports.

By default, mysqldump locks the tables when you run the export. Table locks might cause issues when running in production, so do keep this in mind.

Do not try to copy raw database files to perform a backup. It might lead to corrupted data.

Database dump command:
# This will dump the entire database and place it in the dump.sql file.
docker-compose exec -T \
    --env MYSQL_PWD=your-password db \
    mysqldump your-db-name --add-drop-database -u your-username > dump.sql

You can backup your data without shutting down Corteza server.

Restore the database

Database restore command:
# This will restore the database based on the dump.sql file
docker-compose exec -T \
    --env MYSQL_PWD=your-password db \
    mysql your-db-name -u your-username < dump.sql

We recommend that Corteza server is shut-down until the restore procedure finishes.

Backup uploaded files

Without object storage service like, uploaded files are stored directly on the filesystem. Corteza server is storing data to the /data directory (if not configured differently with *_STORAGE_PATH environmental variables).

You can use any one of the standard file management tools to make a backup copy of the files.

Compressing files with tar command:
# This will compress all your uploaded files into the backup.tar.bz2 archive
tar -cjf backup.tar.bz2 data/server/

Restore uploaded files

Uncompromising files from the archive with tar command:
# This will restore your backup.tar.bz2 archive
tar -xjf foo.tar.bz2
