+## Push notifications
+
+It is possible to configure three push events, that may trigger on the backup cronjob. Those can be used to detect failures from mointoring systems.
+The events are:
+- start
+- success
+- fail
+
+### Using a Prometheus Push Gateway
+
+[A prometheus push gateway](https://git.coopcloud.tech/coop-cloud/monitoring-ng#setup-push-gateway) can be used by setting the following env variables:
+- `PUSH_PROMETHEUS_URL=pushgateway.example.com/metrics/job/backup`
+
+### Using custom URLs
+
+The following env variables can be used to setup push notifications for backups. `PUSH_URL_START` is requested just before the backups starts, `PUSH_URL_SUCCESS` is only requested if the backup was successful and if the backup fails `PUSH_URL_FAIL` will be requested.
+Each variable is optional and independent of the other.
+
+```
+PUSH_URL_START=https://status.example.com/api/push/xxxxxxxxxx?status=up&msg=start
+PUSH_URL_SUCCESS=https://status.example.com/api/push/xxxxxxxxxx?status=up&msg=OK
+PUSH_URL_FAIL=https://status.example.com/api/push/xxxxxxxxxx?status=down&msg=fail
+```
+
+### Push endpoint behind basic auth
+
+Insert the basic auth secret
+`abra app secret insert <backupbot_name> push_basicauth v1 "user:password"`
+
+Enable basic auth in the env file, by uncommenting the following line:
+```
+#COMPOSE_FILE="$COMPOSE_FILE:compose.pushbasicauth.yml"
+#SECRET_PUSH_BASICAUTH=v1
+```
+
 ## Usage
 
+Run the cronjob that creates a backup, including the push notifications and docker logging:
+`abra app cmd <backupbot_name> app run_cron`
 
 Create a backup of all apps:
 
-`abra app run <app_name> app -- backup create`
+`abra app run <backupbot_name> app -- backup create`
 
 > The apps to backup up need to be deployed
 
 Create an individual backup:
 
-`abra app run <app_name> app -- backup --host <target_app_name> create`
+`abra app run <backupbot_name> app -- backup --host <target_app_name> create`
 
 Create a backup to a local repository:
 
-`abra app run <app_name> app -- backup create -r /backups/restic`
+`abra app run <backupbot_name> app -- backup create -r /backups/restic`
 
 > It is recommended to shutdown/undeploy an app before restoring the data
 
 Restore the latest snapshot of all including apps:
 
-`abra app run <app_name> app -- backup restore`
+`abra app run <backupbot_name> app -- backup restore`
 
 Restore a specific snapshot of an individual app:
 
-`abra app run <app_name> app -- backup --host <target_app_name> restore --snapshot <snapshot_id>`
+`abra app run <backupbot_name> app -- backup --host <target_app_name> restore --snapshot <snapshot_id>`
 
 Show all snapshots:
 
-`abra app run <app_name> app -- backup snapshots`
+`abra app run <backupbot_name> app -- backup snapshots`
 
 Show all snapshots containing a specific app:
 
-`abra app run <app_name> app -- backup --host <target_app_name> snapshots`
+`abra app run <backupbot_name> app -- backup --host <target_app_name> snapshots`
 
 Show all files inside the latest snapshot (can be very verbose):
 
-`abra app run <app_name> app -- backup ls`
+`abra app run <backupbot_name> app -- backup ls`
 
 Show specific files inside a selected snapshot:
 
-`abra app run <app_name> app -- backup ls --snapshot <snapshot_id> --path /var/lib/docker/volumes/`
+`abra app run <backupbot_name> app -- backup ls --snapshot <snapshot_id> /var/lib/docker/volumes/`
 
 Download files from a snapshot:
 
 ```
-filename=$(abra app run <app_name> app -- backup download --snapshot <snapshot_id> --path <absolute_path>)
-abra app cp <app_name> app:$filename .
+filename=$(abra app run <backupbot_name> app -- backup download --snapshot <snapshot_id> --path <absolute_path>)

 Like Traefik, or `swarm-cronjob`, Backupbot II uses access to the Docker socket to read labels from running Docker Swarm services:
 
+1. Add `ENABLE_BACKUPS=true` to .env.sample
+
+2. Add backupbot labels to the compose file
+
 ```

-- `backupbot.backup.pre-hook` -- command to run before copying files (optional), save all dumps into the volumes
-- `backupbot.backup.post-hook` -- command to run after copying files (optional)
+    - this is the only required backup label, per default it will backup all volumes
+- `backupbot.backup.volumes.<volume_name>.path` -- only backup the listed relative paths from `<volume_name>`
+- `backupbot.backup.volumes.<volume_name>: false` -- exclude <volume_name> from the backup
+- `backupbot.backup.pre-hook` -- command to run before copying files
+    - i.e. save all database dumps into the volumes

+- `backupbot.restore.pre-hook` -- command to run before restoring files
+- `backupbot.restore.post-hook` -- command to run after restoring files
+    - i.e. read all database dumps from the volumes
+
+3. (Optional) add backup/restore scripts to the compose file
+

+services:
+  db:
+    configs:
+        - source: pg_backup
+          target: /pg_backup.sh

+
+
+configs:
+  pg_backup:
+    name: ${STACK_NAME}_pg_backup_${PG_BACKUP_VERSION}
+    file: pg_backup.sh
+```
+
+Version the config file in `abra.sh`:
+
+```
+export PG_BACKUP_VERSION=v1
+```
 
 As in the above example, you can reference Docker Secrets, e.g. for looking up database passwords, by reading the files in `/run/secrets` directly.

+
+## Backupbot Development
+
+1. Copy modified backupbot.py into the container:
+
+```
+cp backupbot.py /tmp/backupbot.py; git stash; abra app cp <backupbot_name> /tmp/backupbot.py app:/usr/bin/backupbot.py; git checkout main; git stash pop
+```
+
+2. Testing stuff with the python interpreter inside the container:
+
+```
+abra app run <backupbot_name> app bash
+cd /usr/bin/
+python
+from backupbot import *
+```
+
+### Versioning
+
+- App version: changes to `backup.py` (build a new image)
+- Co-op Cloud package version: changes to recipe.
+
+        For example, starting with 1.0.0+2.0.0:
+            "patch" change to recipe: 1.0.1+2.0.0
+            "patch" change to backup.py: increment both, so 1.1.0+2.0.1
+                   because bumping the image version would result in a minor recipe release
