Back up your data electronically, online. It's a hot new, technology that compresses your data to 40-60%, overcoats it with security features, then encrypts with a key and finally stores it in a secure, remote electronic data vault.
The compression means you need less backup storage as well as lower bandwidth for transfer.
The de-duplication technology incrementally backs up only the changed data. It's completely automated - you define the frequency of the backup and the retention period, and PetaVault takes care of the rest.
The best part - no capital expenditure at all. PetaVault is an online service that you can sign up for and start using today.
