Disaster Recovery
The Problem:
Various products offer the ability to replicate backup data between data centers. But in the event of a catastrophic loss of a data center you also need to have the tools to restore catalogs and the context of the lost NonStop systems.
The Solution:
ETI-NET’s BackBox product supports “Inactive” BackBox domains for NonStop DR systems, that can be activated in case of failure of the active system, providing access to backups made by it. The DSM/TC catalog can be restored so that the contents of those backups are meaningful and easily accessible by the DR system.
While BackBox virtual tape data can be replicated between sites by a number of methods, use of Data Domain data de-duplication equipment can significantly improve the efficiency of inter-site link utilization for backup replication, and ensure that the data is received on the DR site promptly, minimizing data loss in case of an outage.
Is there a catch?
No catch. DR site use is common among BackBox customers, and the product capabilities have been developed based on customer feedback.
BackBox™ - Disaster Recovery for NonStop
While each data center with NonStop systems can have one or more BackBox Domains, a special class of Domains called “inactive” have been provided for use in DR sites. Upon primary site failure, an “inactive” Domain can be activated and the virtual tapes defined in it made available to the NonStop systems in that site. By restoring the Volcat from the primary site’s DSM/TC catalog, the tape contents can be made accessible to be restored.
Replication of BackBox virtual tape data between the sites can be implemented using native mechanisms in SAN, NAS or data de-duplication equipment, or by scripted transfers by BackBox VTCs. Data Domain equipment in particular is very efficient in use of inter-site links, as it only transfers modified data “chunks”, and is flexible in scheduling the link bandwidth it can use by time-of-day.
Features:
- Virtual tape storage on SAN, NAS, data de-dup equipment, or an Enterprise Storage Manager
- Multiple NonStop host connections scalable to your throughput needs
- SCSI connections to S-Series, or FC connection to NS-series
- Multiple virtual tape drives on each host connection at no additional cost
- Multiple context-free BackBox VTCs for high availability – no single point of failure
- “Inactive” domains available for DR-site access to primary site virtual tapes
- Configure virtual tape replication by DSM/TC pool
- Shipped pre-configured on HP Proliant servers, or implement on your servers
Benefits:
- Transparent operation with NonStop backup & TMF software
- Improved backup performance and rapid restores
- Grow throughput over time by simply adding host connections and VTCs
- Eliminate loss of access to backups based on automatic re-routing via available VTCs & ports
- Reduced operational overhead with virtual tape
- Much higher reliability backups – eliminate tape media errors
- Minimizes loss of access to backups in case of DR site takeover, and simplifies the takeover process
- Can use HP server equipment for reliability and field service by HP
