Jim Salter<p>Professor Anil Madhavapeddy published a nice step-by-step explainer on how the Energy and Environment Group of his university is beginning to use <a href="https://fosstodon.org/tags/Sanoid" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Sanoid</span></a> and <a href="https://fosstodon.org/tags/syncoid" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>syncoid</span></a> to manage "100s of terabytes of satellite imagery, biodiversity data, academic literature, and the intermediate computations that go along with them."</p><p><a href="https://anil.recoil.org/notes/syncoid-sanoid-zfs" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">anil.recoil.org/notes/syncoid-</span><span class="invisible">sanoid-zfs</span></a></p>

Borg is good too though.</p><p>But these days my first choice wouldn't be any rsync-a-like, I'd go for <a href="https://fosstodon.org/tags/sanoid" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sanoid</span></a> / <a href="https://fosstodon.org/tags/syncoid" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>syncoid</span></a>, which manage <a href="https://fosstodon.org/tags/ZFS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ZFS</span></a> replication and snapshots. Obviously you still need something rsync-ish to get data onto ZFS if the machine you're backing up can't easily use the One True Filesystem.</p>
mk<p>i like syncoid (part of sanoid), because it gives you error messages you can actually work with !</p><p>native zfs send: <br>"cannot receive resume stream: kernel modules must be upgraded to receive this stream."</p><p>syncoid: <br>"Cannot sync now: rpool/data/sshfs/media is already target of a zfs receive process."</p><p>wtf, kernel modules must be upgraded?</p><p>1. kill zfs receive process on target<br>2. resume send with syncoid</p><p>i love zfs, but these error messages are fucking awefull !</p><p><a href="https://mastodon.satoshishop.de/tags/zfs" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>zfs</span></a> <a href="https://mastodon.satoshishop.de/tags/proxmox" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>proxmox</span></a> <a href="https://mastodon.satoshishop.de/tags/sanoid" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sanoid</span></a> <a href="https://mastodon.satoshishop.de/tags/syncoid" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>syncoid</span></a></p>
Borjan Tchakaloff<p><span class="h-card" translate="no"><a href="https://mastodon.social/@geerlingguy" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>geerlingguy</span></a></span> <a href="https://freiburg.social/tags/sanoid" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sanoid</span></a> &amp; <a href="https://freiburg.social/tags/syncoid" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>syncoid</span></a> are really neat. At some point I was even using a <a href="https://freiburg.social/tags/raspberryPi" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>raspberryPi</span></a> 1 as a backup host, no need for a lot of power/bandwidth if you don't deal with terabytes of changes at once :)</p>
