Backup and restore

Manual backup process


This requires direct access to the PostgreSQL server from the machine on which the backup is done:

PGPASSWORD=<password> pg_dump -O -h <hostname> -U <username> <dbname> > <date>.sql


The command for backing up the InfluxDB is the following:

influxd backup -portable -host <hostname>:8088 -database <dbname>

Manual restore process

Hibernating the Tenant by adding the option `hibernate: true` to the tenant's global configuration section and reapplying the tenant configuration:

  name: ...
  hibernate: true



This config can then be applied with the following command:

helm upgrade -f <tenant-name>.yaml <tenant-name> <chart>

After a few moments, use kubectl again to check if the tenant is fully hibernated:

kubectl get pods -n <tenant>

There should not be any pods left in the tenant (evicted pods can be ignored). Once the tenant is fully hibernated, the databases can be restored.

Restoring PostgreSQL

First ensure that the schema is cleared and any existing (possibly corrupted) data is deleted:

PGHOST=<host> PGPASSWORD=<password> PGUSER=<user> PGDATABASE=<dbname> psql -qAtX -c "DROP SCHEMA IF EXISTS %s CASCADE;"

Then, the actual backup can be applied:

PGHOST=<host> PGPASSWORD=<password> PGUSER=<user> PGDATABASE=<dbname> psql -f <filename>

Restoring InfluxDB

For restoring influxdb, simply run:

influxd restore -portable -host <hostname>:8088 <backup-dir>

Dehibernating the tenant

Remove the `hibernate=true` section from the config file again and apply the tenant's configuration again (see above for specific steps).
