All actions on the mailstore including deleting of mail or mailboxes is reflected in the backup.
Therefore if a user deletes mail, the backup will also not contain the deleted mail.
Vaultastic in contrast, secures a copy of all the mail sent and received by a user at a secondary location. This ensures that even if a user accidentally or intentionally deletes mail from the primary mailbox, it is still available in the Vaultastic store.
