# Back up the production Peek desktop profile (the 'default' profile holding the
# user's real data) before installing a new build. READ-ONLY on the source.
#
# Usage:
#   scripts/backup-prod-profile.sh              # full profile (everything, GBs)
#   scripts/backup-prod-profile.sh --datastore  # just datastore.sqlite (+wal/shm)
#
# Only datastore.sqlite is migrated by a new app build, so --datastore is the
# sufficient safety net for a build test; the full profile also includes the
# (build-stable, regenerable) chromium storage + caches. Backups are timestamped
# under ~/Library/Application Support/Peek-backups/. Restore with
# scripts/restore-prod-profile.sh <backup-dir>.
