Guys, Your comments on the following...
"Because datasets are platform and configuration-specific, they should not be used for long-term backup and recovery of source data"
Thanks

So, for long term backup should we load them to sequential files eventually?
Thanks and Regards!!

Absolutely yes... what if the environment changes? Your datasets won't match to the nodes they were defined against back in the day. Flat files provide a much more stable option for recovery.

Not necessarily. Database tables serve just as well.
