I am looking to see how other shops are currently doing Backups for DR and
OR. I think this will be valuable for the archives.
Currently I have the following processes in Place. Any suggestions or
guidelines for this analysis will be appreciated.
2 EMC VMAX arrays (could be Hitachi or IBM). 2 Geographically dispersed
Data Centers (one VMAX in each)
So in my hypothetical setup I have
Prod VMAX is Snapping my Prod data within the VMAX
Prod VMAX is Replicating to the Secondary (Dev and Text) VMAX (SRDF/A)
My Secondary VMAX (Dev and Test) is Snapping the Replicated data
I have weekly backups to Tape
I have DFHSM doing backups/ML2 tapes are shipped to secondary site.
So do I have overkill? .
With the stability of the EMC VMAX I am not sure I would need 3-6 copies of
data
I am not sure that the weekly backups are required with this configuration
The main intent was to ensure if there was corrupted data, there would be a
copy of the data that might not be corrupted somewhere.
So, the questions
What do you do for your shops for DR and OR/BC (Operational
Recovery/Business Continuity).
How do you ensure you have a prior copy of data in-case of corruption?
How to you plan for a DR TEST vs. a True DR condition? How do you handle
your DB2/IMS/CICS databases for transition during DR TEST or REAL event?
And how often do you do a DR test (Paper or validation IPL?
How do you know if you are taking to many backups (for the Just IN Case
issue) that is just stealing cycles from valid workload?
Do your DBAs take their own backups, and how do you ensure that you are
not overlapping with them?
I am not going to ask about the infrastructure (VTAM, Servers, Network
backbone, DNS connections) I think that is too much to deal with.
Not all shops have this configuration, so I am looking for general
guidelines (and I have been reading white papers on DR until my head spins).
Until I there is a failure -it is not clear if a proper and efficient
Backup/DR Plan that will cover a majority of managements concerns.
And all of the tapes that are shipped offsite are encrypted, so another
layer to deal with.
Any thoughts or considerations.
Thanks Everyone in advance.
