Dump and Restore

Dump

You can use the command pg_dump as explained on our documentation. But you cannot restore it on a PostgreSQL using TimescaleDB hosted on Scalingo.

The only dump available to make restorable backups on Scalingo hosted TimescaleDB are the on demand backups. The reason is that the restoration process must be done by the Scalingo support using these specific backups, see below.

Note that Point-in-Time Recovery backups are still working normally.

Restore

The backup restoration on TimescaleDB requires a specific process to be done on the PostgreSQL database as it is explained on TimescaleDB official documentation. A temporary database should be used for the backup restore and the following command should be executed using admin rights:

SELECT timescaledb_pre_restore();
\! pg_restore -Fc -d exampledb exampledb.psql
SELECT timescaledb_post_restore();

On Scalingo, default user does not have admin rights on database, this means that this process must be done by an operator of the support.

Warnings

Several points are important to take into account.

Make sure you keep track of which versions of PostgreSQL and TimescaleDB you are running during backup process. For more information, see “Troubleshooting version mismatches” of official documentation.

You cannot backup an individual hypertable, pg_dump creates dumps that do not contain the information needed to properly restore the hypertable from a backup.

You can find more details on the TimescaleDB documentation: “logical backups with pg_dump and pg_restore”.
