This is with regards to home computing data, not business data. I'm amazed at how people think hard drives will last forever. The average user doesn't appear to ever do backups, which I find to be a scary situation, considering hard drives aren't really designed to last more than a few years. People often have one drive in their computer, and never think about it. Backing up data via CD-R quickly went away for me, due to the sheer volume of data. My music collection alone would take about thirty CDs, I gather. I got a DVD burner, but hardly think that's a great choice either. Besides, the reports are scary at how long recordable media actually lasts. I'd hate to make an archive, go back to it in two years, and find that the CDs / DVDs were unreadable. I previously ran all my data on a linux file server, with RAID 1 for the data. Sadly, I'm between linux servers right now, as the motherboard gave up hope after a meager four years of service. Before telling myself it was overkill, I thought I should have a RAID 5 hot-swap disk system, rsyncing the data nightly to an external USB disk as well. (At least I wasn't thinking of doing daily full / weekly incremental backups to tape, and dropping a set every other week at a bank safe deposit box.) Online backup is too slow / too costly when data exceeds a few gigs, and disk solutions pretty much will fail at some point, so keeping data seems to be a constant battle. The more I think about it, the more I think I'm overthinking it. So I toss it to the OT community -- what do you do for data safeguarding? Obviously there's a tradeoff between convenience and timeliness (recent backups as opposed to an every once-in-a-while); there's also a tradeoff between the cost of a solution and the value of your data. What do people here do?
