Resources:

Note: if you need to backup PostgreSQL database, see poc-postgresql-walg

Backup scenario

Put some data to backup in data/:

$ mkdir -p data
$ (cd data; curl -L https://github.com/restic/restic/archive/master.tar.gz | tar -xz)

Start Minio (s3 like) service:

$ docker-compose up -d s3

Start Restic service:

$ docker-compose up -d restic
$ docker-compose logs -f restic

Default backup cron configuration: BACKUP_CRON="0 */6 * * *"

This is how to execute backup now:

$ docker-compose exec restic /bin/backup.sh
Starting Backup at 2020-04-04 09:10:59
Backup Successfull
Finished Backup at 2020-04-04 09:11:01 after 2 seconds

You can go to http://127.0.0.1:9000/minio/bucket1/ to see backup data in Minio (S3 like) bucket.

Restoration scenario

Now I would like restore file outside Docker.

$ brew install restic

$ source source.env

$ restic -r s3:http://127.0.0.1:9000/bucket1 snapshots
enter password for repository: secret
repository bf543bcb opened successfully, password is correct

$ restic -r s3:http://127.0.0.1:9000/bucket1 check

check snapshots, trees and blobs
no errors were found

Restore data to data2/:

$ restic -r s3:http://127.0.0.1:9000/bucket1 restore a90a2c8b --target ./data2/
enter password for repository:
repository bf543bcb opened successfully, password is correct

$ du -h -d0 data
26M	data
$ du -h -d0 data2
