You may also want to look into using the -m option to htdig for minimal updates to a database. > Is step (b) necessary? Not if the URL is the same. When htmerge encounters 2 records with the same URL, it takes the most recent one. > What are the time requirements of htpurge and htmerge?

Total elapsed time depends on too many factors for me to give a meaningful answer. The only way to know what it'll be for your circumstances is to try it and time it. The htpurge step should be quite quick, even for a large db, though I expect it to be quicker still on a smaller db. The htmerge step would be more time-consuming. -- Gilles R.
