The duration of retention of emails in your Vaultastic vaults is entirely in your control. You can define separate retention periods for each vault if you so need. This feature could help you determine retention as per the person’s role.
If you are concerned about the storage growth and cost escalation, you can leverage Vaultastic’s storage tiering architecture to move aging, infrequently used data into the Inactive store. Learn more about Vaultastic’s stores.
