What options are there to regularly move #ZFS snapshots to a remote target that does not run ZFS?

zfs send feels clumsy. zfs-autobackup and zrepl do not support non-ZFS targets. What's left?

#freebsd

In each case, the system is creating and replicating snapshots regularly.

Most of the latency deltas you're seeing come from the snapshot/replication tasks. Without those, you do still get ZFS advantages—but not this catastrophically severe.

Note that #btrfs is displaying latencies two and sometimes THREE orders of magnitude higher than #ZFS across a disturbing amount of the range of results. This is not just an issue at the absolute fastest or slowest ends of the scale, this is... normality.

Wrote a quick update on what I've been up to, now that it's been two months since I left Canonical, and what to expect next! #incus #linux #zfs #debian

Why do I have to keep running #fsck to fix the bit map? #DebianLinux, 1T HD. Would #ZFS or Btrf preclude this problem? Most annoying!

Por cierto, parece que tendré que reformatear mi disco porque #ZFS sí me consume mucha RAM (tengo 8GB y en reposo se consume poco más de la mitad).

En foros veo es un problema recurrente, que sí tiene parece ser una explicación lógica pero al menos yo no la termino de entender.

Además mi swap no lo configuré a consciencia y es de solo 2 GB.

Volveré al típico #ext4.

Un petit restore basé sur la table activities de Nextcloud, sur plusieurs snapshots zfs! Pfiou!

@dekkzz76 I'm interested, #bcachefs' first-class support of caching devices and encryption are particularly interesting.

The fact it adds that *without* adding #ZFS' flaws of mostly requiring devices all the same size and not coping well with downgrading (enterprise assumptions™) is also part of what interests me (these are essential features #btrfs provides).

I'm probably going to wait for #SQLite and other #databases to have time to implement what support they need for it.

oops i forgot that because i use #zfs i have to do a deferred launch of #Arq because i have to unlock half a dozen filesystems via ssh before i login to windowserver and apparently i haven't done that in quite a while :grimace:

the good news is that the only things likely to have changed since july are things on zpools and those are redundant and backed up via #znapzend!

#zfs mafia recognize :joy:

Just discovered that #ZFS permissions delegations are almost useless on Linux, since it's 100% possible to create and manage datasets as a user (non-root), but not to mount them.
(it's a known and documented limitation)

I'm frustrated.

#PSA: You can have a degraded zraid without #ZFS actually showing a problem. I had a raid with a really, really bad write performance and an even worse read performance for the whole raid. Thankfully /var/log/messages hinted to a problem with one of the drives. Nothing serious, just some caching timeout. So I replaced that drive to check if that would change something. And thankfully it fixed the problem. Oh, and btw: Always keep spares around!

#ZFS for Dummies

https://ikrima.dev/dev-notes/homelab/zfs-for-dummies/

My #ZFS snapshot tool `zfsnapr` has been updated.

`zfsnapr` lets you recursively mount snapshots of your ZFS filesystems on a given location - primarily intended for backups using non-ZFS-aware tools.

The latest version finally supports limiting operations to specific pools (-p/--pool), and handling of missing mountpoints, e.g. due to parts of the system not being ZFS.

The latter also makes -r/--root more flexible as it is no longer restricted to a mountpoint.

Die ITler in meinem Alter sollten eigentlich alle wissen was #zfs im Detail ist und bedeutet ... aber es gibt ja auch noch den Nachwuchs. Zudem wollte ich mein Gedächtnis noch mal prüfen und Auffrischen und die Einführung von ZFS in #opnsense bot die Anlass sich die Thematik ZFS nochmals genau anzusehen. Hier der Link zu meinem Blogartikel zu dem Thema.
