Each port on the new backbone will provide a dedicated 12 fold increase when compared to the existing shared token ring backbone. Layer-3 is used by routers to forward data to the appropriate destination. This alleviates the need for customers to purchase a dedicated router or burden a server with the routing function in order to connect to the backbone. This does not mean that agencies should move away from token ring. We do that for disaster recovery purposes.
Users code how many days the tape is to be vaulted.
Some do backups daily, some weekly. Because the vault is strictly for temporary storage of disaster recovery tapes, our policy, for years, has been that tapes should stay in the vault no longer than 30 days. We have been liberal in enforcing the rule. Naturally, some users took advantage and began routinely coding retention dates of 60 days or more. Consequently, over time, our vaulting processes became hard to manage.
