High Availability Backup Strategy 4
With your High Availability configuration you will essentially follow a
traditional backup routine for two CMS servers instead of just one.
Therefore, follow the normal CMS server backup/restore process and
schedule for traditional, non-High Availability systems as described in
“
Backup & Restore Procedures”.
In addition, have a set of dedicated
synchronization tapes capable for
one backup of
each CMS server. Whenever you make a change to a
CMS server that you would like to back up and restore to the other CMS
server, perform a manual backup.
Synchronizing
after an
unscheduled
outage of the
Primary CMS
server 4
This scenario presumes users are temporarily logged into the Secondary
CMS server because the Primary CMS server was down.
1. After the Primary CMS server is back up and running, note the date
and time and perform a full maintenance backup of the Secondary
CMS server.
2. Put the Primary CMS server in single-user mode.
3. On the Primary CMS server, restore both the ACD-specific and CMS
Administration data from the Secondary CMS server full
maintenance backup (only if you made administration changes on
the Secondary CMS server while the Primary was down).
4. Put the Primary CMS server in multi-user mode.
5. Wait for an interval to complete and be archived.
6. Restore the specific start/stop and time/date historical data to the
Primary CMS server to recover the needed data.
7. Tell users to log off the Secondary CMS server and log back into the
Primary CMS server.
