Who says sync/sharing is not a backup? Is the goal a backup not to have two or more copies of your data in different locations? If the datacenter happens to fail, your other copy would be the local one, correct? Swapping backup drives/tapes isn't without it's own problems. What happens if the bank building burns down? Or the drive/tape becomes corrupt? Computer dies before your bi-monthly/quarterly drive swap? For me, using a live sync solution provides a better backup solution than dealing with SneakerNet. My backups are up to the minute and automatic and redundant (computer -> ownCloud -> S3 in other region). I personally have no time for dealing with manually backing up our personal computers and swapping a drive at my banks vault. My solution works for me because it solves my problem of having offsite backups (and recovery) and keeps it simple. The trick is to find what works for you because if it's burdensome and complicated you're not going to do it or you're going to forget about it. With all these idea/solutions we're playing the odds. What are the odds that my cloud instance, S3 and my local computer all die at the same time? What are the chances that my computer dies the day before I get a backup to disk and take it to the bank? Don't write off sync technologies/services as not acceptable. Evaluate what your needs are and what is acceptable for data loss is and make a choice based on that. For some the cost of hosting their own sync server will not be worth it and a backup drive taken to the bank is "good enough".
