I have an Open edX system run entire in only one server, but system performance is bad. Its RAM consuming is being increased day by day, now I wan to backup and restore to other bigger server.

Document of Open edX is hard to reach this information, and I've searched for a while but don't get what I want. If you know this, please guide me on this problem

Many thanks,

You need to backup edxapp and cs_comments_service_development database in mongodb and all data from mysql.

Backing up: 

mysqldump edxapp -u root --single-transaction > backup/backup.sql
mongodump --db edxapp
mongodump --db cs_comments_service_development

Restoring: 

mysql -u root edxapp < backup.sql
mongo edxapp --eval "db.dropDatabase()"
mongorestore dump/
It worked for me. Copies all courses, accounts, progress and discussions.

Idea taken from BluePlanetLife/openedx-server-prep, for more details, look here

This might not be a exact answer also not a standard solution for production environment, but might help you.

Manual way can be as follows:

  1. You can setup a new edX instance on a new server.
  2. Update all your repos edx-platform, custom xblocks to appropriate branch,tag.

(The database replacement point 3 and 4 below i haven't tested for production environment.)

  1. replace the mysql databases 'edxapp', 'ora', 'xqueue' in new server with older ones.

  2. replace mongodb databases 'cs_comments_service_development', 'edxapp' in new server with older ones.

    I was able to replace mysql 'edxapp' database on the devstack.
