After talking with the backup software vendors (Spectrum, Tivoli, Symantec, Commvault, etc) it became clear that adding another backup target wasn&amp;#x27;t something we (AWS) could get them to prioritize, for perfectly reasonable reasons. We could (and did) apply pressure via our shared customers, even then they estimated it would take years.&lt;p&gt;The fastest way to enable large enterprise access to S3 and Glacier for backups was to meet them where they were. We did this by virtualizing a tape library.&lt;p&gt;Background: I&amp;#x27;m one of the original inventors - &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;image-ppubs.uspto.gov&amp;#x2F;dirsearch-public&amp;#x2F;print&amp;#x2F;downloadPdf&amp;#x2F;10013166&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;image-ppubs.uspto.gov&amp;#x2F;dirsearch-public&amp;#x2F;print&amp;#x2F;downloa...&lt;/a&gt;.

In a large enterprise, the backup configuration can be wildly complicated, a matrix of systems, schedules, slas, etc. Just reconfigure your backup software to use this new virtual tape device and you&amp;#x27;re on your way.</text><parent_chain><item><author>SCdF</author><text>Dumb question, and I&amp;#x27;m guessing this is a &amp;quot;if you don&amp;#x27;t know it&amp;#x27;s not for you&amp;quot; situation, but what is the point of a virtual tape?
