avidamoeba, (edited ) in Sanity check - is rsyncing to a remote computer that has zfs snapshotting an okay way to back things up?
@avidamoeba@lemmy.ca avatar

Using plain rsync sounds sane.

Sending local ZFS snapshots to the remote ZFS might be problematic. Consider accidentally deleting important data locally and nuking all of your local snapshots, then sending that to the remote ZFS. You lost all of your snapshots and there’s no way to recover the deleted data. Instead do what I do - keep the two ZFS systems separate and use a non-ZFS mechanism to transfer data - rsync, Syncthing, etc. That way even if you delete everything locally, nuke all local snapshots and send the deletions via rsync remotely, you could still recover your data by restoring the remote ZFS to a snapshot prior to the deletions. For reference I have two ZFS machines doing frequent snapshots and Syncthing replicating data between them on immediate basis.

!selfhosted, please do critique if you find some fundamental issues with this.

abies_exarchia,

This is fantastically helpful, thank you. I will do this.

I don’t know why I thought sending zfs snapshots was the better option

Cause it makes sense at a glance and it’s efficient. Not for backup purposes though.

BCsven,

Zfs send / receive might be what you want

avidamoeba,

Wouldn’t send/receive also sync snapshots across ZFS instances?

BCsven,

Docs say this , so yeah. "send streams can either be “full”, containing all data in a given snapshot, or “incremental”, containing only the differences between two snapshots. ZFS receive reads these send streams and uses them to re-create identical snapshots on a receiving system. "

ryannathans,

You don’t sync the deletion of snapshots, you use expiry on the remote

That is rsync.net’s entire business model.

I still rclone my Borg repos there instead of relying on snapshots though.

taaz,

I also use rsync.net but as direct host for my borg repos, why rclone after?

knobbysideup,
@knobbysideup@sh.itjust.works avatar

It works the same either way. Borg does a lot of different backups on my home network. I also have more than just Borg backups that I want off-site, so an rclone of everything from that nas share once after everything else is done makes more sense than duplicating Borg everywhere. The rclone’d stuff can be used directly just like if it was put there by Borg itself.

icanwatermyplants, in Does anyone else harvest the magnets and platters from old drives as a monument to selfhosting history?

Back in the day I bought a fridge freezer combo, second hand, no handles. Used to be a built in model. As handles I used two magnets from full height drives, they were ludicrously strong and shaped like a little bit like a handle.

Full height drives were 3.25" high for those who are wondering.

kanzalibrary, (edited ) in Encrypted fileshares in the local network?

Maybe you can experiment Croc if you want simplest way.

MigratingtoLemmy,

I would like this for my media server, basically like a drop-in replacement for NFS shares. I still need it to be some sort of share instead of having to prompt it to send media across. Great project though, thanks

AbidanYre, in Redundancy? storage options for a rpi4? filesystems? raid?

With two drives you can extend them into one big drive or you can mirror them, but you can’t do both.

will just keep on keepin’ on then

Telodzrum, in Private and/or cheap places to register a domain

Namecheap, Namesilo, and Porkbun are the ones that people around here seem to like.

possiblylinux127, in Redundancy? storage options for a rpi4? filesystems? raid?

A btrfs raid 1 array would make the most sense.

MNByChoice, in Sanity check - is rsyncing to a remote computer that has zfs snapshotting an okay way to back things up?

Have you tried a restore? A non-differential smap snapshot should be fine, but differential snapshots would make a restore difficult to impossible.

A zfssend and zfsrestore with a differential snapshot would be more traditional. If one put mbuffer in the middle, it would even be fast.

I don’t know of anything built for that purpose but you could use home assistant dashboards to pull it off pretty easily if you already have an instance set up.

uninvitedguest,
@uninvitedguest@lemmy.ca avatar

That’s an interesting thought. Thank you, I’ll toy around with that.

fibrechips, in Looking for a self hosted Dementia Clock

Any reason to have it be self hosted, or really Internet connected? I can think of a few reasons, but I’m curious your use case.

I know they make $15-20 standalone units that are just what you’re looking for, but not Internet connected at all.

shmanio, in Jellyfin video stutters on some files (all MKV it seems)
@shmanio@lemmy.world avatar

It could be an issue with the codecs (browsers are usually pretty limited in what they support). You could try to use a client like Jellyfin Media Player instead. It bundles libmpv, so it plays almost any video format there is.
