Disaster Recovery Planning (DRP) is the technology component of the Contingency Planning process. There are a number of options and levels of preparedness available to organizations relating to DRP which GSC provides clients. The following outlines the various services:

Backed Up Site
• Hot Site (Mirror Site)
• Warm Site
• Cold Site
Online Automated Hot Back Up services
Online Automated Warm Back Up Services
Exchange Server Redundancy
In all of the redundancy solutions outlined, clients typically prioritize the business importance of their applications in order determine the level of redundancy required. Systems and applications that are mission critical which must be 100% up at all times require a higher level of redundancy than other systems.
GSC provides either complete Managed Services or simply Co-Location Hosting for clients who want to utilize our redundancy capabilities. The following outlines the various redundancy options available to clients at EXG:
| Hot Site (Mirror Site) |
Clients can utilize the GSC Data Centre to house their redundant hardware, operating system and applications that are fully mirrored with their primary site’s data centre. This allows clients to have complete “live” redundancy of their systems available in the event of a disaster at their primary site. In the event of a disaster or any of their applications becoming unavailable for various reasons, the systems are designed to automatically failover to the GSC hosted mirrored site such that the users are unaware that the primary system has failed. This ensures complete technological and business continuity. Being an offsite solution ensures continuous technological availability in the event the client’s primary physical / logical server or office location problems cause unavailability of the primary server site.

| Warm Site |
Clients can utilize the GSC Data Center to house their redundant hardware, operating system and applications that are fully backed up with their primary site’s servers. This allows clients to have “Warm” redundancy of their systems available in the event of a disaster at their primary site. In the event of a disaster or any of their applications becoming unavailable for various reasons, the systems are designed for a manual failover to the GSC hosted backed up site. There is a decision point when an organization’s IT management activates the Warm site and brings users back online utilizing the GSC hosted backed up site as the new primary site. The data at the Warm site is typically backed up over night so the data loss for the organization will normally be limited to the current day’s activities. Being an offsite solution ensures near continuous technological availability in the event the client’s primary physical / logical server or office location problems cause unavailability of the primary server site.

| Cold Site |
Client’s who do not require either a Hot Mirrored Site or a Warm Backed Up Site environment, can rent contingency Conditioned Server Floor / Rack Space. This provides organizations who experience a disaster access to a conditioned server room environment for recreating their server environment once they have procured the replacement hardware, operating system and applications. For some clients, there are certain systems and applications that do not required immediate recovery and this option provides the organization with the contingent server room space required to recover over an extended period of time once the mission critical applications are operational.

Online Automated Hot
Back Up Services |
GSC provides an online hot automated back up service for clients’ data. This service involves a bit-level streaming back up service. As a client’s primary site data bases are updated, our client application performs a continuous bit-level steaming backup of the changed data to an off-site server at the EXG hosting facility. The system is designed to hold 30 to 60 days of backed up data on our disk storage device which is available via the internet for on demand client controlled file level restore to the client’s primary site. This reduces the risk at the primary site for failure of the tape backup procedures or tape restore procedures. Further, since it is an immediate online restore procedure, file recovery time is significantly reduced since offsite tapes do not need to be retrieved, mounted and tape restored. Organizations are viewing the tape backup procedure for archiving purposes rather than the primary restore source.

Back Up Services |
GSC provides a warm automated back up service for clients’ data. This service involves a bit-level streaming back up service. With this service, the client’s primary site data bases are backed up over night utilizing our bit-level steaming backup service of the daily changed data to an off-site server at the GSC hosting facility. The system is designed to hold 30 to 60 days of backed up data on our disk storage device which is available via the internet for on demand client controlled file level restore to the client’s primary site. This reduces the risk at the primary site for failure of the tape backup procedures or tape restore procedures. Further, since it is an immediate online restore procedure, file recovery time is significantly reduced since offsite tapes do not need to be retrieved, mounted and tape restored. Organizations are viewing the tape backup procedure for archiving purposes rather than the primary restore source.

Exchange Server
Redundancy |
Over the past number of years, eMail has become the primary communication tool and mission critical to most organizations. In the event of a primary site disaster, organizations have recognized that eMail is a critical business tool for communication both within the organization and with key business partners (customers, suppliers, their financial institutions, shareholders, etc.). Besides a complete primary site disaster, day to day operations can be significantly impacted if the organizations’ eMail becomes unavailable. As such, GSC offers specific eMail Exchange server redundancy service. This includes streaming replication of an organizations’ Exchange server mail database with failover to the GSC off-site redundant server in the event of the primary site’s Exchange server becomes unavailable.
