[Question] Restore PostgreSQL and Cassandra backups into Docker tb-cassandra

Hi, I’ve have a question about how to restore PostgreSQL and Cassandra backups into a docker container created with the image tb-cassandra. Basically I had a previous installation of Thingsboard + PostgreSQL + Cassandra into file system. Now I have a docker container which works good, I need to import all backups (.sql file from postgre and the .tar from cassandra), has anyone some advice to do that?

Thanks!

Haven’t tried it, but theoretically it should work to:

1. Create a new folder ${NEW_FOLDER}
2. Copy /var/lib/postgresql/11/data or /var/lib/postgresql/12/data (your local postgresql installation) to ${NEW_FOLDER}/db
3. Copy cassandra folder of your local Cassandra installation to ${NEW_FOLDER}/cassandra (check if it contains subfolders like data, commitlog…)
4. Create .firstlaunch and .upgradeversion files, last one containing the version of your current Thingsboard Docker installation (i.e. 3.3.1) inside of ${NEW_FOLDER}
5. Set 777 permissions to ${NEW_FOLDER} (see here)
6. Set up docker-compose.yml file, defining ${NEW_FOLDER}:/data under volumes
7. Enjoy

That should work, but I haven’t tried (maybe doing it tomorrow). Backup your data before trying. As you see, I wouldn’t do it by using your backup files as Thingsboard uses the whole database installation folders.

@fgnm Hello, We are using the docker exec command for PostgreSQL, and sstableloader for Cassandra e.g. restore for PostgreSQL: docker exec -i container_name psql --username postgres -d db_name </path/on/your/machine/dump.sql and for Cassandra: sudo sstableloader --verbose --nodes 127.0.0.1 ./thingsboard/ts_kv_latest_cf
