Re: I refuse to do backups - on principle
I work at a very large company and we have Autonomy Connected Backup installed on everybody's laptops so apparently my 100,000 employee company considers the storage investment worthwhile. Granted CNB does have a very effective de-dupe component so the 100 or so TB needed is a drop in the bucket of our 4-5 petabytes of storage.
I feel your pain on PST files since big ones are more prone to corruption and people around here have years worth of email squirreled away.
