Back Up and Disaster Recovery Services
A sound business continuity / disaster recovery plan is critical to a business's long-term success. Business continuity planning spans a range of services from restoring data after major system failure, recovering after catastrophic acts of nature (our data centers are fully backed by surplus fuel and generators), planning for security breach, and office continuity (we have conference rooms, individual offices with computers and LANs to house your employees).
We offer a full suite of data synchronization and recovery procedures depending on customer's needs. For customer systems that require additional guarantees of reliability we have implemented solutions: "mirror" server, load balance servers and can also implement geographically dispersed mirror solutions should this be needed, as we have two data center locations. We strive for fault tolerance system - planning for no single point of failure.
Backup and Restore Services
Internal server backup : The server's system, data and user disk drives would most likely be configured in RAID arrays (RAID1, RAID5, RAID10 etc.) to protect against hardware failure of individual disk drives. In addition, the server has an additional volume of suitable size where daily and weekly backups can be stored on an automated basis. Restoration is manual, and could be either controlled by the Customer or by ADTI staff on request. Restoration times would typically be anything from minutes to hours depending on the size of the restore. The server's disk drives would most likely be configured in RAID arrays (RAID1, RAID5, RAID10 etc.) to protect against hardware failure of individual disk drives. This methodology would be best suited for non mission-critical servers where a downtime of several hours or even a day or so is tolerable.
Backup to an external storage array network ( SAN ): All servers requiring backup could be connected to a central SAN (over a high-speed gigabit network), which in turn consists of RAID disk arrays to protect against disk drive failures, and is also backed up regularly to tape. This has the advantage that each server does not need to have additional internal storage space for backups, and the backup storage is saved on a secure, protected device independent of the server. ADTI can make SAN space available in chunks of 25GB, up to 4 terabytes of space on an EMC Clarion CX400, as well as other smaller SAN devices and arrays.
Backup to an external tape drive or array library: This will provide a similar level of backup and recovery as an internal server backup, but with the difference that the storage media is a tape which can be removed, cataloged and stored separately for indefinite storage.
Backup to tape with off-site storage: ADTI can arrange to have tapes saved and shipped to a secure, off-site facility for safe storage and recall, on a daily, weekly, monthly or other schedule as desired by customer.
Backup to a clustered server, in a "fail-over" configuration: The cluster could be configured in "active-passive" or "active-active with load balancing". This would provide rapid recovery from server failures.
