An application to backup PostgreSQL databases and files for use within my home Kubernetes cluster.
- Automatically scales down a given Kubernetes workload (e.g.
Deployment) prior to performing backups and will scale it back to the original number of replicas after it has finished performing the backup operation. - Can connect to a PostgreSQL server and make a backup using
pg_dump. - Can also connect to a MongoDB server and make a backup using
mongodump. - Creates new backups using
rsync, using hard links to save on storage usage. - Can automatically rotate out older backups as newer ones are created.
The application itself is written using Rust and is deployable via a provided Helm chart. Please see the documentation and code for the application to learn more about how to build, run, and configure the application and then read through the Helm chart and its documentation to learn more about how to deploy the application to a Kubernetes cluster.
backup-tools does not have any automated facility for restoring from backups. It is expected that an administrator restore file backups to the correct locations and, if necessary, execute the correct database restore tool using the database backups.
To restore a PostgreSQL backup:
cd /path/to/directory/with/toc.dat
pg_restore -h hostname.local -p 5432 -U username --create -Fd -d database .To restore a MongoDB backup:
cd /path/to/directory/with/mongo.gz
mongorestore \
--gzip \
--archive=mongo.gz \ # '=' here is _required_!
-u admin \
--authenticationDatabase admin
