    snap shots Backup script

    Das war nur ein Beispiel. PVE kann ja kein S3. Wenn du also mehrere Medien auf PVE möchtest, wären das PBS, VZDUMP, vermutlich Veeam, oder halt in der VM selbst irgendwie wegsichern. Gut, das könnte ich dir vorwerfen, wenn du behauptest ein S3 bucket oder ein PBS mit nur write access wäre nicht...

    PBS Incremental Backup

    ...across multiple blocks in a VM. I have no checked this, but I would assume this due to the file vs. block based backup setting. The deduplication rate would also be pretty huge if the containers share the OS. I tested this with ZFS and deduplication and the space savings were huge. EDIT: typos

    snap shots Backup script

    ...Angreifer nicht auf PBS2 „pivoten“, weil PBS2 aus deren Sicht gar nicht erreichbar ist. Alternativ könnte man statt eines zweiten PBS auch eine ZFS-Pull-Replikation vom ersten Backup-Server verwenden. Dann hätte man zusätzlich noch eine zweite Backup-Technologie beziehungsweise ein anderes...

    ...Medien. Das ist aber eben nicht der entscheidende Punkt. Dann hast du die Definition von Medien im modernen Kontext nicht verstanden. Ein ZFS send mache ich mit ZFS. Hat der ZFS code einen Bug, ist eventuell mein ZFS backup wertlos. Ein S3 backup zu AWS mache ich mit einer API. Hat die API...

    Ram report issue to multiple Hosts

    Do you use PCIe-passthrough? And like others already mentioned, check ZFS ARC usage with: zarcsummary -s arc

    First Proxmox homelab build - sanity check on hardware, service layout, and storage

    Please note that the need of ECC-RAM for ZFS is quite overblown: https://jrs-s.net/2015/02/03/will-zfs-and-non-ecc-ram-kill-your-data/ This blog post is quite long (but still good and highly recommended!) reading, the most important point imho is that it r references a comment by ZFS developer...

    Ram report issue to multiple Hosts

    ...Linux based, run lsmod | grep balloon just to confirm the driver is loaded. Once it's working the host usage should come down a lot. Sometimes ZFS ARC on the host eats a ton of free RAM too, worth checking with free -h. It shows as buff/cache. There is a difference between free RAM, Unused...

    ZFS ARC going high since PVE 9.1 upgrade

    ...about 1-6GB on each hosts). Today I was emptying one server, rebooted it and after a couple of hours memory is again full. I have a feeling that ZFS ARC reserves too much of it. Attached you can find 2 screenshot with the consumption over the whole day. any idea or suggestion for solving...

    ...them in mind once I've got the basics running. The removable-disk idea for offsite PBS copies is something I'll definitely work in. Noted on the ZFS/ECC topic — though I've already got the board and non-ECC RAM sitting here, so ECC isn't really on the table for this build anyway. I'll have a...

    Correcting Storage

    Hi @nleistad, Confidently attributing the issue to NFS, QCOW, ZFS, network, or any other component requires proper analysis. This typically includes log review, reproducible testing, and potentially network trace reading. There are known edge cases with QCOW on NFS, particularly around...

    Correcting Storage

    ...by NFS. I now believe that I mistakenly created qcow2 disks for the VM clients and wonder if part of my issues stem from qcow2 stacked on top of ZFS' COW? It looks like I can migrate disks and convert from qcow2 to raw. Would like a little confirmation that this is the correct path to take...

    ...recht, aber ein air-gapped System, das die Backups pullt, hat einen ähnlichen Effekt, womit wir wieder bei einer Pull-Replikation auf Basis von ZFS wären. Kommt halt auch darauf an, wovor und vor wem man die Backups schützen will. Am besten kombiniert man verschiedene Ansätze. Und wirklich...

    Ditching Unraid in favor of Proxmox for ZFS storage shares?

    ...such complicated schema with so many layers/break points, why not use the same disks directly on PVE? You could achieve all of it by using the same disks by PVE as LVM or ZFS storage. It's not complex and exciting as it is now, rather, just boringly reliable) Could you clarify what the main goal?

    ...Käse geschrieben? Kein Problem gibt noch das S3. Wenn PBS einen üblen Bug hat, nützt mir ein zweiter PBS vermutlich auch nix. IMHO heisst die 2 nicht "zwei Festplatten", "zwei S3" oder "zwei PBS". Also nicht Stückzahl zwei Medien, sondern zwei unterschiedliche Medien. "PBS & S3", "PBS & ZFS"...

    PBS: Less space on tape used than expected

    ...I'm a bit confused about the reported size: The VM disk has a maximum size of 20T Inside the VM, df reports 14T used The disk is stored on ZFS with compression enabled and has a reported USEDDS of 8.4T The PBS inventory reports a "Bytes used" of only 4.7T for the tape containing a snapshot...

    ...Nextcloud clients and server version sin sync - so we switched to SFTPGo on LXC with WebDAV+sshfs support. - Works very smooth so far. With zfs you should be at least aware of the the ECC-RAM topic. BTRFS with RAID1 could be a alternative. With BTRFS you might also like to look into a bcache...
