Client (a bit clumsy but positive and honest) calls: "Help! Just came back from lunch break and accidentally deleted all files on the file server!"
Me, unfazed: "Alright, besides you, who else worked on the file server during lunch break?"
Client: "No one, we were all away and I'm the first one back. Others will be back by 15:00"
Me, looking at the clock and noticing it's 14:30: "Okay, what time did you go to lunch?"
Client: "At 13:30. How long will it take to restore from the backup? Do you think we'll be able to work tomorrow?"
Me, without flinching as I type "zfs rollback *dataset-13:45-snapshot": "Done"
Client: "All the files reappeared!"
Me: "Thank #ZFS, #FreeBSD, and whoever set up automatic snapshots every 15 minutes."

@bsi Fast ebenso wichtig wie #Sicherungen (#Backups): ein kleiner Vorrat regelmäßiger "#Schnappschüsse" (#snapshots) vom aktuellen Zustand aller Dateien, mit denen Nutzer:innen selbständig eine kleine Zeitreise rückwärts machen können, ohne jemand um "Wiederherstellung" bitten zu müssen.

Es wird häufiger unbeabsichtigt oder leichtsinnig etwas gelöscht, was man eine Woche später dann doch wieder bräuchte.

Somehow #VirtualBox #snapshots are superior to #ZFS snaps.

Afaik, in "ZedFS" 😉 , you can't have a current state that's younger than a snapshot | bookmark | checkpoint | clone.

The only way to achieve this, is to replicate the whole dataset | volume with zfs send and receive.

@pilhuhn Ich habe gar nicht so viele Daten bisher gesammelt, aber ich backuppe alles mit @syncthing von zuhause auf meine @Hetzner_Online Storagebox via eine #VM

Nebeneffekt:
Da läuft noch eine @nextcloud auf der VM und fertig ist:

1. Backup
2. Mobiler Zugriff (readonly bzw. mit Versionierung in #syncthing und #snapshots auf dem #storage )
3. "Ersatz" für den vermurksten NC Client, der nur läuft, wenn man am Desktop angemeldet ist

Ansonsten noch das obligatorische #rsync Backup mit #rear (#relaxandrecover) auf eine externe disk für schnelles, weil lokales wiederherstellen.

#datensparsamkeit

When deleting data from any snapshot-enabled filesystem, keep in mind that deleting data actually means _adding_ data - if an earlier snapshot of your dataset exists.

That means: Migrating 80 GB of PostgreSQL from version 11 to 13 does not only mean + 80 GB of new, migrated data, but +160 GB of added data if you delete the old database files.

It has bit me more than once. Soo. just keep that in mind if you use snapshots :D :thisisfine: 🔥

#zfs #snapshots #server #mastoadmin

I just accidentally #deleted the directory containing my latest project.

Last #backup 2 weeks ago, so before I started. The backup helped recover the supporting files.

I recovered most source files from open files in the text editor - it was set not to reload changes files (whew).

In the end, only #git history is gone. I should push to my server (with daily #snapshots) more often.

All in all, redoing a week of recent work is not terrible, so I'm okay with my system.

#accident

Mit der Nutzung des Btrfs-Dateisystems und der Verwendung von Snapshots kann jeder Linux-Benutzer seine Daten effektiv schützen und schnell wiederherstellen. #Linux #Btrfs #Snapshots #OpenSource

@michabbb Fwiw, i use #Snapshot not #Stable, & have done so for many years. Ofc the raison d'etre of #Snapshots is to help the Devs find bugs before the next Stable releases. Thus, some Snapshots can be a bit rough, however, over the years, numerous times, certain Snapshots arrive that make me explicitly remark to myself; "this, THIS one, is THE best #VivaldiBrowser ever". It's a nice feeling each time that happens.

Feel grateful to have the award-winning @HornimanMuseum in our neighbourhood 🌳
Here's some #snapshots from a recent beautiful sunny evening wandering around the #gardens there ☀️

@marcel @ActionRetro This issue is OFC far less of a problen on modern systems with #Journaling #Filesystems and #Snapshots as well as #Checksumming...

So on #APFS, #ZFS & #btrfs as well as even #ext4 in #journalless-mode the lilelyhood of loosing data unless one were to bake a device is negligible.

@ariadne like everything from #Veeam.

Their #Backup software is only being licensensed from gullible Enterprises that have more money than sense, cuz otherwise they'd not use shitty OSes like Windows that require 3rd party backup solutions and can't do proper backups via #Snapshots or other means like #rsync...
