Topics 7 tiers of disaster recovery defined by SHARE Users group 1993 Key Technologies Storage networks Disk storage Tape automation Software Solutions
Understanding Your Business Risks How long can you afford to be without your IT systems? Recovey Time Objective (RTO) How much data can your company afford to lose? Recovery Point Objective (RPO) How much of your companies network must be restored in order to continue operations? Network Recovery Objective (NRO)??
Seven Tiers of Business Continuity Tier 0 - No offsite data Tier 1 - Pickup truck access method (PTAM) Tier 2 - PTAM + hot site Tier 3 - Electronic Vaulting Tier 4 - Active secondary site Tier 5 - Two-site two-phase commit Tier 6 - Zero data loss
Tier 0 Tier 0 - No offsite data no saved information (data, instructions, documents) no determination of requirements no backup hardware no contingency plan Typical recovery time unpredictable (includes never)
Tier 1 Tier 1 - Pickup truck access method (PTAM) selectively saved data determination of requirements optional backup hardware and backup facility available contingency plan available Typical recovery time usually more than a week Daily
Tier 2 Tier 2 - PTAM + hot site all requirements of tier 1 sufficient hardware and network to support the installation's critical requirements Typical recovery time usually more than one day Daily at Recovery Time
Tier 3 Tier 3 - Electronic Vaulting all requirements of tier 2 electronic vaulting of a some subset of information (e.g. transaction logs) Typical recovery time usually about one day Daily Daily at Recovery Time
Tier 4 Tier 4 - Active secondary site active management of recovery data by a processor at the recovery site bi-directional recovery physically separated Typical recovery time usually up to one day High Bandwidth connections Daily at Recovery Time
Tier 5 Tier 5 - Two-site two-phase commit requires tier 4 selected data in image status (updates to both sides within a single commit scope) requires partially or full dedicated hardware on secondary site capability to automatically transfer workload Typical recovery time less than 12 hours High Bandwidth connections
Tier 6 Tier 6 - Zero data loss immediate and automatic transfer to secondary site data is considered lost if ENTER has been accepted at the terminal, but the request has not been satisfied on the storage device Typical recovery time a few minutes advanced coupled High Bandwidth connections Data Sharing system

Storage Networks Application Server Direct Attached SCSI or FCS SCSI Protocol No sharing Limited connectivity Server centric storage Inefficient and expensive Application Servers Storage Area Network (SAN) FCS SCSI Protocol S A N Multiple heterogeneous servers sharing storage High performance dedicated storage network Extended distance - up to 100km High connectivity/availability - multiple paths Capacity and data sharing. Clients & Servers Network Attached Storage IP Network File Protocol (CIFS,NFS,HTTP,FTP,etc) NAS Clients sharing files Uses existing IP network and skills Very large distances - LAN, MAN, WAN Quick and easy to implement Capacity and file sharing
