Because tapes are <i>much</i> less fragile than hard disks, and I can stash a bunch of tapes in my safe deposit box and other places.  As well as have <i>many</i> copies of my data as I keep monthly full backups for at least a year.  And, hmmm, my tapes as I use them are more reliable than my Seagate enterprise disks, and that&#x27;s with the latter not moving around (i.e. in all my post-mid-2011 tornado hardware, I&#x27;ve had two disk failures and no tape failures).<p>For the level of data security I want, and the tiny AT&amp;T DSL straw I&#x27;m currently forced to use, even with things like Amazon Snowball and ever lower prices on &quot;nearline&quot; cloud storage, <i>if</i> a tape drive lasts long enough, the numbers work better for tape.  And compared to the usual enterprise, I don&#x27;t beat up on tape drives, they&#x27;re over-engineered for my duty cycle.  I also have a desire to be able to make due without monthly charges, which a cloud solution doesn&#x27;t allow.<p>And, yeah, TB not GB.  The DAT tapes I used previously were in the GB range as I vaguely recall.
