Well to I have always thought this way.
1. you have the "fuzzy" files (online etc).
2. you have your batch files which in most cases you can be a PIT
backup.
You pick a PIT and do you backups and you can back up everything but
the ONLINE files.
Any online system that is up 24X7X365 has there own needs and have to
do their own.
most batch systems who do not touch online are relatively each.
The people that designed the online *MUST* have their own facility
for back up and continuation services.

At one place I worked there was one "system" that updated several
hundred volumes over the space of the day. We had their DASD mirrored
in a far off place. Once in a while it went a little wacky and if
people didn't notice it immediately heads rolled. I stumbled on the
fact that it wasn't being mirrored correctly and reported it and I
think 6 people got fired.

Shane,
To your point. Anything we do with ABARS or DFDSS dumps will most
likely be "fuzzy" as many files are always open under CICS/IMS/MQ/
DB2, etc....
To harden the data to make the backup useful would require an
outage in some cases.
So I appreciate everyone's input. There is a lot to consider.

So, when determining your backup strategy, first determine your
recovery
needs and then determine which backup technique will best fit
those needs.
The elephant in the room is that there is no way to have complete
confidence in backups - of whatever nature. They may be "consistent"
(FSVO), but are they valid ?.
And if they are bad, there is no way to know how far back you need
to go to
get a "good" copy. And whether your business could survive going
back that
far.
