Tape drives were never a good choice for consumers, CD-Rs and DVD+Rs were too small and too slow. This leaves only one question: Where to back up to? And Mac OS X has had its excellent TimeMachine feature for quite a while now.
(Much less an easy way to restore a backup, if needed.) But Windows 7 has a good backup system now and Windows 8 has an even better one. Originally the problem of backing up was not having a reliable, yet automated program. And even those of us who do take backups, well, we don’t do it often enough.
It is 2015 and almost no one takes backups. It is this author’s opinion that 2015 should be the ‘Year of the Backup’.
