(I feel like I've violated plenty of common-sense stuff while learning ZFS. If so, you can let me have it in the comments.)

I have a large RAID-Z1 array that I back up to a USB 3.0 hard drive. I'd also like to maintain zfs-auto-snapshot's snapshots as well. I've been doing a zfs send MyArray | zfs recv Backup and it's been working pretty well; however, once in a while, the array will become suspended due to an I/O error, and I'll either need to reboot, or rarely, destroy the backup disk and re-copy everything.

This seems like I'm doing something wrong, so I'd like to know: what is the best way to back up a ZFS array to a single portable disk?

I would prefer a portable backup solution like backing up to a single USB hard drive (preferably so I can buy two and keep one somewhere secure), but I'm open to getting a small NAS and zfs sending over a network.

I’d like to think Lemmygrad’s operators keep their connection logs fairly well-protected, and store as little user data as possible.

I’d honestly be more concerned about opsec (operational security). For example, you might post in an apolitical thread about how you live outside of a city, you work at a local coffee shop, or maybe your username is “redcarowner69”. There’s three facts about you that someone with too much free time (or nation-state funding) can begin to arrange.

I’m not sure if this is legally binding, but it’s a way to prove that someone said “I signed this document and it has not been modified.” While S/MIME certificates are most commonly used for this purpose, getting one (especially for free) is nearly impossible. Signing with a GPG key is just using another tool, one whose ecosystem doesn’t require CA-sanctioned trust; the reader decides which keys are trusted and verified.

How about we renegotiate the Civil War? Is it too late to give them the southern states and tell them to leave us alone?

I’ve got a Bolt and I refuse to pay for OnStar. There’s an LTE modem in the car, and every so often, they call me asking if I want to activate it.

Thanks for the warning. I’ll keep my eyes open. Perhaps it’s time to start distro-hopping.

It could be a processing limit. What’s your upload speed? Have you tried enabling Smart Queues?

Lately, I’ve been listening to Ghost’s “Impera”. The front half is better, but the second half is still quite solid.

I use the Windows version of Scrivener 3 on Linux. It works almost perfectly. Sometimes it’ll freeze after opening a file, but force-quit and restart the app, and it’s fine.

Good point. It was quite the adventure trying to find drivers for my T470’s fingerprint reader. It’s been working great ever since, but it was a long road.

Awesome! Now, if only I could move my Mastodon toots or PixelFed photos to another server. Sure, I can redirect my accounts, but then I’m stuck with the old content on another feed.

The project would have to support reproducible builds somehow. For example, supply a Makefile and a hash of the generated executable.

Interesting. Mine sometimes fails to wake up with ZFS. I wonder if automatic snapshots are the culprit.

 

She’s a good cat.
