Rob Thomas<p>Wanna know when the WORST time is to do a massive amount of disk IO, moving stuff around? When a drive has failed and it's resilvering. Sigh. At least it's <a href="https://mastodon.au/tags/zfs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>zfs</span></a> so you can trust it'll work and your data is safe! Well. It's *your* data, <a href="https://mastodon.au/tags/mastodonau" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mastodonau</span></a> not mine. But still, WORST POSSIBLE TIME FOR IT TO FAIL.</p>

Paul Buetow<p>I guess the way to go for a <a href="https://fosstodon.org/tags/FreeBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>FreeBSD</span></a> storage solution which is HA is HAST (block level replication), CARP (VIP failover), <a href="https://fosstodon.org/tags/ZFS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ZFS</span></a> file system (with some scripts exporting/importing the file system from the HAST-replicated block devices on failover), a NFS server (which starts/stops together with the active ZFS replica), and a WireGuard tunnel to encrypt NFS traffic over the network. And some periodic ZFS snapshots and regular background scrubbing. Not sure if CARP can build a quorum with 3 nodes?</p>

Ramin Honary<p><span class="h-card"><a class="u-url mention" href="https://mastodon.social/@var" rel="nofollow noopener noreferrer" target="_blank">@<span>var</span></a></span> it’s nice to have a separate dedicated computer for managing the backup. You really need to have all backup disks attached to SATA. USB is not reliable for backup purposes because is likely to lose data when a sudden power outage occurs. So if you have (for example) 4 disks that all attach to SATA, that is a lot of IO happening, which you really don’t want when you are using your computer for other things that may need that IO, especially games or multimedia. You’ll notice the performance hit if it is backups are happening on a computer that you use for other things.</p><p>Also, it’s nice that the NAS comes with software that takes care of things like software RAID-1 or <a class="hashtag" href="https://fe.disroot.org/tag/zfs" rel="nofollow noopener noreferrer" target="_blank">#ZFS</a> for you.
