<p class="MsoNormal">Hi<br>
<br>
Wondering what people are doing for offsite store / backups. Looking at <a href="http://it.slashdot.org/story/14/11/26/0044239/is-lto-tape-on-its-way-out" target="_blank">
http://it.slashdot.org/story/14/11/26/0044239/is-lto-tape-on-its-way-out</a> LTO tapes sales are down. People are backing up to disk.<br>
<br>
But what are people doing for offsite. Removable HDs ?<br>
