How to backup NOC

All instructions are for singlenode installation.

Creating Backup

It's necessary to do backup of both databases(MongoDB + PostgreSQL) simultaneously due to complex links between data.

1. Stop NOC services: systemctl stop noc

2. Do backups:

3. mongod: mongodump --db=noc --username=noc --password=noc -v --out=/backup/mongodump/ --gzip
4. postgresql: sudo -u postgres pg_dumpall -c -f /backup/pg_dumpall.out -v -U postgres

5. clickhouse: look at this link or just backup the /var/lib/clickhouse/ if you want to save metrics

6. Start NOC services: systemctl start noc

Restoring Backup

1. Empty databases and then load them with your data

2. Stop NOC services: systemctl stop noc

3. MongoDB:

4. cd /opt/noc/ && ./noc mongo

5. db.dropDatabase();

6. mongorestore --db=noc --username=noc --password=noc --gzip mongo_noc/noc/

7. Postgres:

8. sudo -u postgres psql

9. drop database noc; (all postgres clients should be stopped: noc, pgbouncer, grafana-server)

10. sudo -u postgres psql -f pg_dumpall.out

VM Backup

Virtual Machine backup is also an acceptable option, but it may not be file consistent as direct DB backup.
