# Hetzner Volumes for Nextcloud Data Storage
#
# Each client gets a dedicated volume for Nextcloud user data.
# Volumes are independent from server instances, enabling:
# - Independent storage scaling
# - Easy data migration between servers
# - Simpler backup/restore procedures
# - Better separation of application and data
