Volumes¶

Host path	Container	Purpose
`${PIHERDER_BACKUP_HOST_PATH:-./backups}`	`/backups`	rsync destinations for server backups
`./piherder_backups`	`/herder_backups`	PiHerder self-backup archives (chown uid 1000 if permission errors)
`./piherder_data`	`/data`	Avatars + service logos (Settings live in Postgres)
`./certs`	`/certs` (Caddy, ro)	`fullchain.pem` + `privkey.pem`

Secondary disk example:

PIHERDER_BACKUP_HOST_PATH=/home/you/backup

web and celery-worker must share the same /backups (and usually /data, /herder_backups) for multi-worker correctness.
