Stefano Marinelli<p>Client: Help, emergency. I have 24 hours to move my workload to another server. What do we do? <br>Me, five minutes later: "Done. Your workload is now running on the new server." <br>Client: "How did you move over 200GB with just a minute of downtime, from one provider to another and in a different country?" <br>Me: "Thanks to FreeBSD, ZFS, and a little bit of proactive planning."</p><p>I have a task that replicates all the VMs from one server to another every 15 minutes using zfs-send/zfs-receive. This VM connects to a VPN with two reverse proxies. <br>Meaning, when I move this VM, we don’t need to change any IPs since it’s not directly exposed. <br>I powered it off, cloned the differences in seconds, and restarted it. </p><p>Client in disbelief. <br>Me, relaxed and happy. </p><p>Thank you, FreeBSD, thank you, ZFS! </p><p><a href="https://mastodon.bsd.cafe/tags/FreeBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>FreeBSD</span></a> <a href="https://mastodon.bsd.cafe/tags/ZFS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ZFS</span></a> <a href="https://mastodon.bsd.cafe/tags/TechSupport" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>TechSupport</span></a> <a href="https://mastodon.bsd.cafe/tags/ServerMigration" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ServerMigration</span></a> <a href="https://mastodon.bsd.cafe/tags/OpenZFS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OpenZFS</span></a> <a href="https://mastodon.bsd.cafe/tags/SysAdmin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SysAdmin</span></a> <a href="https://mastodon.bsd.cafe/tags/RunBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RunBSD</span></a></p>
