Institute a backup plan. Duke departments, OIT and Research Computing and others have different ways to ensure that data are backed up regularly and appropriately. Be sure to establish a backup plan (PDF document) at your project's outset. A general rule for backup is the 3-2-1 rule and does scale depending on how backups are structured - 3 copies (1 original, two backup), on 2 different types of media, with at least 1 off-site (physically) or in separate, dedicated cloud storage.
Determine project roles to establish governance. Define project roles to ensure that read, write or execute permissions are assigned appropriately. Come up with a storage hierarchy that addresses these permissions as a means to preserve workflow order.
