The future of much of astronomy is in high data-volume surveys, many of which will generate Petabytes of data. Pulsar astronomers have been generating such data volumes for the past five years or so in their quests to find (primarily) faint radio millisecond pulsars which are useful for a variety of basic physics "experiments". While the surveys themselves are quite specific in their desired outcomes (i.e. new pulsars), the data products are fairly generic and could be used for other science purposes (i.e. fast radio transients, high-redshift HI absorption line studies...). Given that these very large datasets are produced on National facilities, it is interesting to ask, therefore, whether they should all be archived and made available for everyone. And if so, at what cost? In this talk I'll mention some of the science that we are after in these surveys, some of the logistical difficulties we have dealing with hundreds of TB of data with only small teams, and possible non-pulsar uses of such surveys.
