+## Introduction
+
+Copycat DB is a [service](https://github.com/ente-io/infra) to take a backup of
+our database. It uses the Scaleway CLI to take backups of the database, and
+uploads them to an offsite bucket.
+
+This bucket has an object lock configured, so backups cannot be deleted before
+expiry. Conversely, the service also deletes backups older than some threshold
+when it creates a new one to avoid indefinite retention.
+
+In production the service runs as a cron job, scheduled using a systemd timer.
+
+## Required environment variables
+
+##### SCW_CONFIG_PATH
+
+Path to the `config.yaml` used by Scaleway CLI.
+
+This contains the credentials and the default region to use when trying to
+create and download the database dump.
+
+If needed, this config file can be generated by running the following commands
+on a shell prompt in the container (using `./test.sh sh`)
+
+    scw init
+    scw config dump
+
+##### SCW_RDB_INSTANCE_ID
+
+The UUID of the Scalway RDB instance that we wish to backup. If this is missing,
+then the Docker image falls back to using `pg_dump` (as outlined next).
+
+##### PGUSER, PGPASSWORD, PGHOST
+
+Not needed in production when taking a backup (since we use the Scaleway CLI to
+take backups in production).
+
+These are used when testing a backup using `pg_dump`, and when restoring backups.
+
+##### RCLONE_CONFIG
+
+Location of the config file, that contains the destination bucket where you want
+to use to save the backups, and the credentials to to access it.
+
+Specifically, the config file contains two remotes:
+
+* The bucket itself, where data will be stored.
+
+* A "crypt" remote that wraps the bucket by applying client side encryption.
+
+The configuration file will contain (lightly) obfuscated versions of the
+password, and as long as we have the configuration file we can continue using
+rclone to download and decrypt the plaintext. Still, it is helpful to retain the
+original password too separately so that the file can be recreated if needed.
+
+A config file can be generated using `./test.sh sh`
+
+    rclone config
+    rclone config show
+
+When generating the config, we keep file (and directory) name encryption off.
+
+Note that rclone creates a backup of the config file, so Docker needs to have
+write access to the directory where it is mounted.
+
+##### RCLONE_DESTINATION
+
+Name of the (crypt) remote to which the dump should be saved. Example:
+`db-backup-crypt:`.
+
+Note that this will not include the bucket - the bucket name will be part of the
+remote that the crypt remote wraps.
+
+##### Logging
+
+The service logs to its standard out/error. The systemd unit is configured to
+route these to `/var/logs/copycat-db.log`.
+
+## Local testing
+
+The provided `test.sh` script can be used to do a smoke test for building and
+running the image. For example,
+
+    ./test.sh bin/bash
+
+gives us a shell prompt inside the built and running container.
+
+For more thorough testing, run this service as part of a local test-cluster.
+
+## Restoring
+
+The service also knows how to restore the latest backup into a Postgres
+instance. This functionality is used to periodically verify that the backups are
+restorable.
+
+To invoke this, use "./restore.sh" as the command when running the container
+(e.g. `./test.sh ./restore.sh`). This will restore the latest backup into the
+Postgres instance whose credentials are provided via the various `PG*`
+environment variables.
+
+## Preparing the bucket
+
+The database dumps are stored in a bucket that has object lock enabled
+(Compliance mode), and has a default bucket level retention time of 30 days.
+
+## Deploying
+
+Ensure that promtail is running, and is configured to scrape
+`/root/var/logs/copycat-db.log`.
+
+Create that the config and log destination directories
+
+    sudo mkdir -p /root/var/config/scw
+    sudo mkdir -p /root/var/config/rclone
+    sudo mkdir -p /root/var/logs
+
+Create the env, scw and rclone configuration files
+
+    sudo tee /root/copycat-db.env
+    sudo tee /root/var/config/scw/copycat-db-config.yaml
+    sudo tee /root/var/config/rclone/copycat-db-rclone.conf
+
+Add the service definition, and start the service
+
+    scp copycat-db.{service,timer} instance:
+
+    sudo mv copycat-db.{service,timer} /etc/systemd/system
+    sudo systemctl daemon-reload
+
+To enable the cron job
+
+    sudo systemctl enable --now copycat-db.timer
+
+The timer will trigger the service on the specified schedule. In addition, if
+you wish to force the job to service immediately
+
+    sudo systemctl start copycat-db.service
+
+## Updating
+
+To update, run the [Github action](.github/workflows/ci.yaml) to push the latest
+image to our Docker Registry, then restart the systemd service on the instance
+
+    sudo systemctl restart copycat-db

+
+### Backup timeout
+If you are seeing time-out from scw while waiting for backup, usually just stopping the [service](.copycat-db.service) and letting the [daily timer](./copycat-db.timer) restart it later works
