# 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
