# deploy/dalidou/cron-backup.sh
# ------------------------------
# Daily backup + retention cleanup via the AtoCore API.
#
# Intended to run from cron on Dalidou:
#
#   # Daily at 03:00 UTC
#   0 3 * * * /srv/storage/atocore/app/deploy/dalidou/cron-backup.sh >> /var/log/atocore-backup.log 2>&1
#
# What it does:
#   1. Creates a runtime backup (db + registry, no chroma by default)
#   2. Runs retention cleanup with --confirm to delete old snapshots
#   3. Logs results to stdout (captured by cron into the log file)
#
# Fail-open: exits 0 even on API errors so cron doesn't send noise
# emails. Check /var/log/atocore-backup.log for diagnostics.
#
# Environment variables:
#   ATOCORE_URL           default http://127.0.0.1:8100
#   ATOCORE_BACKUP_CHROMA default false (set to "true" for cold chroma copy)
