<pre dir="auto">G'day all,<br><br>I've gone and bought an LTO-5 tape drive with the intention of supplementing our already pretty comprehensive backup routine. It won't fit in any of my on-line machines, so the intention is to put it into the office "workshop" machine with a fast disk, stage the backup onto the disk and then write it out to tape overnight. I don't need partial writes or recovery. There will be no issue writing or reading the whole tape. If I need to recover from tape I have bigger issues than the time required.<br><br>My thought is to use tar through compression and then encryption streamed out to tape. I'll have a play with compression and encryption that can sustain damage and still recover the remainder as a belt and braces.<br><br>Anyone have any tips or ideas?<br><br>Regards,<br>Brad<hr>PLUG discussion list: <a href="mailto:plug@plug.org.au" target="_blank">plug@plug.org.au</a><br><a href="http://lists.plug.org.au/mailman/listinfo/plug" target="_blank">http://lists.plug.org.au/<wbr>mailman/listinfo/plug</a><br>Committee e-mail: <a href="mailto:committee@plug.org.au" target="_blank">committee@plug.org.au</a><br>PLUG Membership: <a href="http://www.plug.org.au/membership" target="_blank">http://www.plug.org.au/<wbr>membership</a><br><br><br></pre></blockquote></div></div></blockquote><br><br>-- <br>Linux supports the notion of a command line or a shell for the same<br>reason that only children read books with only pictures in them.<br>Language, be it English or something else, is the only tool flexible<br>enough to accomplish a sufficiently broad range of tasks.<br> -- Bill Garrett<br>
