will be as follows:
RPO: Near-zero (This may vary depending on the quality of the network
connection.)
RTO: 2 hours (To be determined after verifying recovery procedures in an actual
DR environment, even if the system will be recovered within 2 hours but it will
take a few hours [totally up to half a day] for verification from the business point
of view.)
Table 3-16 Measures for DR
DR site
location
Nay Pyi Taw
DR site will be set up in the server room of the CBM Nay Pyi
Taw Head Office.
DR site
design
Hot standby
At the DR site, infrastructure for CBM-NET will be installed
and configured. The CBM-NET system will be up and
running at the DR site.
Data
replication
Asynchronous
data
replication
Business data of CBM-NET will be replicated
asynchronously between the primary site and the DR site,
by using the database function.
Asynchronous replication is adopted because it can be used
regardless of the distance between the primary and DR sites.
In addition, near-zero data loss can be achieved by using the
database replication function.
Redundancy
Same as
Primary Site
Basically, DR Site has the same configuration of Primary
Site. When the system is operated in the primary site, these
servers are also used for development environment.
Resource
usage
Resources will
be shared
between DR
system and
development
system.
At the DR site, there will be two sets of servers.
In the normal state, one set will be up and running as CBMNET standby servers, replicating data with its counterpart
at the primary site. There will be no incoming access to
CBM-NET servers at the DR site.
Another set will act as the development environment for
CBM-NET.
CBM-NET
Target
systems
CBM-OA, MCH, and the accounting system will not be set
up at the DR site.

states.
