Disaster
Recovery
The A98
solution includes redundant, mirrored hard drives to assure continued operation
in the event of a single hard drive failure. Upon a failure, the system
automatically begins using the mirrored drive. The defective drive is replaced
by TSS per the maintenance agreement and a utility is run to synchronize the
new drive. The unit also includes dual front mounted USB ports as a mechanism
to produce backups of the system for on/off-site storage.
Potential
disaster recover plans are:
1) utilize the standard
A98 backup features only. Since re-keying is not a mission critical
application, in a disaster event, re-keying would be done manually (as today)
and the exception logged. After recovery, any manually re-keyed ATMs (if done
in a non-compliant manner) would be re-keyed using the restored A98. If the A98
unit is rendered inoperable, a replacement unit from TSS could be provided
within 30-days or sooner.
2)
a cold backup unit, on-site. This provides for immediate
availability if the primary A98 fails due to a non-disk drive defect, e.g.
processor, memory, VRU card. The disk drives from the failed unit are simply
inserted into the cold backup unit. After the phone and network cables are
transferred, the system is back in operation. In the case of a data center
disaster, option 1 above would be followed.
3)
a redundant A98 unit, at a Disaster Recovery site. Since this
backup unit is a duplicate of the primary system, it is fully operational in
the case of a disaster. The data will be kept in sync using a network shared
drive or USB drive backups from the primary unit. After re-routing the A98
phone number and restoring the latest backup, the DR unit would be operational.
