# Backups
|
||
|
||
The `famapp-backup` service performs nightly compressed `pg_dump` of both
|
||
`famapp-db` and `authentik-db` at **02:00 server time**.
|
||
|
||
## Storage layout
|
||
|
||
```
|
||
/backups/ (named Docker volume: famapp_backups)
|
||
famapp/
|
||
daily/ ← last 14 days
|
||
weekly/ ← last 8 Sundays
|
||
monthly/ ← last 6 first-of-month dumps
|
||
authentik/
|
||
daily/
|
||
weekly/
|
||
monthly/
|
||
```
|
||
|
||
Dump files are named `YYYY-MM-DD.dump` in custom (`-Fc`) format (internal
|
||
compression, ~3–5× smaller than plain SQL).
|
||
|
||
## Retention
|
||
|
||
| Tier | Kept | Trigger |
|
||
| ------- | ---- | --------------------- |
|
||
| daily | 14 | every night |
|
||
| weekly | 8 | Sunday night |
|
||
| monthly | 6 | 1st of the month |
|
||
|
||
Retention is enforced by `retain.sh` at the end of each `backup.sh` run.
|
||
|
||
## Restore procedure
|
||
|
||
### 1. Identify the dump
|
||
|
||
```sh
|
||
# List available dumps
|
||
docker exec famapp-backup-1 ls /backups/famapp/daily/
|
||
```
|
||
|
||
### 2a. Restore inside the backup container (recommended)
|
||
|
||
```sh
|
||
docker exec famapp-backup-1 /scripts/restore.sh \
|
||
/backups/famapp/daily/2024-06-01.dump \
|
||
postgres://famapp:SECRET@famapp-db:5432/famapp
|
||
```
|
||
|
||
Replace `SECRET` with the value of `FAMAPP_DB_PASSWORD` in your `.env` file.
|
||
For authentik:
|
||
|
||
```sh
|
||
docker exec famapp-backup-1 /scripts/restore.sh \
|
||
/backups/authentik/daily/2024-06-01.dump \
|
||
postgres://authentik:SECRET@authentik-db:5432/authentik
|
||
```
|
||
|
||
### 2b. Restore to a separate database (safe — non-destructive)
|
||
|
||
Create a fresh target database first, then restore into it:
|
||
|
||
```sh
|
||
# Create the target DB
|
||
docker exec famapp-db-1 createdb \
|
||
-U "$FAMAPP_DB_USER" famapp_restore
|
||
|
||
# Restore
|
||
docker exec famapp-backup-1 /scripts/restore.sh \
|
||
/backups/famapp/daily/2024-06-01.dump \
|
||
postgres://famapp:SECRET@famapp-db:5432/famapp_restore
|
||
```
|
||
|
||
### 2c. Restore on a fresh host (disaster recovery)
|
||
|
||
```sh
|
||
# Copy the dump file out of the volume
|
||
docker cp famapp-backup-1:/backups/famapp/daily/2024-06-01.dump ./
|
||
|
||
# Spin up a temporary Postgres container and restore
|
||
docker run --rm \
|
||
-e PGPASSWORD=SECRET \
|
||
-v "$(pwd)/2024-06-01.dump:/dump.dump:ro" \
|
||
postgres:16-alpine \
|
||
pg_restore -h <new-db-host> -U famapp -d famapp \
|
||
--no-owner --no-acl /dump.dump
|
||
```
|
||
|
||
## Off-site replication
|
||
|
||
The backups live in the `famapp_backups` Docker named volume. To copy them
|
||
to another host, rsync the volume's data directory periodically (e.g. from a
|
||
host cron job):
|
||
|
||
```sh
|
||
# On the Docker host, add to /etc/cron.d/famapp-rsync:
|
||
30 3 * * * root rsync -a --delete \
|
||
/var/lib/docker/volumes/famapp_backups/_data/ \
|
||
user@offsite-server:/opt/famapp-backups/
|
||
```
|
||
|
||
Encryption at rest is handled at the disk/filesystem layer (e.g. LUKS).
