Hehe.. datahoarder. I think many of us are. For me it is over pure laziness.
Got my self 2 rackmount NAS servers with 12x 12TB drives in each unit. And instead of using the opportunity to sort and clean up the dat I had on my other NAS units, I just created 1 Share folder for each existing NAS (on the rackmount unit) and then just dumped everything in there. There... Consolidated into a single NAS. But no time to sort

I recently cleaned up my office in the basement, to redo the floor, new paint and recessed lights. during the cleanup, I came by many of my old backups from the days of tape backups. Still had piles of DDS 4mm tapes, some DLT4 tapes, and even some Sony AIT cartridges. I even found 2 QIC-1000 tapes, but those were still new in packaging, probably left over from a previous cleanup. Scary part is, I still had all the drives to be able to read the media. But decided if I had not used them in the last 10+ years, then I probably did not need them, or had copies elsewhere. So just destroyed all the tapes.
