# Daily email backup — downloads new emails via IMAP to atlantis NFS mount
#
# Writes directly to /mnt/atlantis_archive/old_emails/ (NFS mount to atlantis:/volume1/archive)
# Also keeps a local copy at /tmp/gmail_backup for quick access
# Incremental — skips already-downloaded .eml files
# Never deletes — emails removed from source stay in backup
#
# Proton Bridge must be running for admin@thevish.io backup.
# If bridge is down, Gmail accounts still back up fine (script continues on error).
