A good systems analysis is a must in whatever one does.  Be it system
admin, software developer, accountant, lawyer etc.

My suggestion about using "find" was in response to OP's
question/clarification on incremental/differential backup and I
assumed due diligence with respective to designing the script.

how to perform a differential backup using rsync?

On web there is a great confusion about diff backup concept when
searched with rsync.

rsync will do incremental backup as already discussed earlier in this thread.

Please suggest  how to achieve a differential backup with rsync (the
original query).
