    Hello! I have found this very interesting PVE-zsync thing, I would like to use it, but I have read IP addresses must be used to configure it. I have two PVE hosts in two different locations. I would like to sync them so that one is redundant of the other for a quick disaster recovery. They are...

    pve-zsync error: destination has snapshots and daylight saving

    Hi. I use pve-zsync as backup solution between servers, sometimes with a periodicity of less than an hour. From time to time, this error arises: cannot receive new filesystem stream: destination has snapshots (eg. rpool/data/vm-1106-disk-0@rep_mv06-servidor16_2023-10-25_17:00:01) must destroy...

    Migrating VMs to New Server with PVE-Zsync - Very Slow and Progress Reverts when Interrupted

    So I have an old server and a new server, both are running proxmox. I was attempting to migrate about 600GB of data. It didn't need to be migrated quickly, but it's taken nearly two weeks. I ran the command inside of screen. One of the servers rebooted due to power outage and it literally erased...

    General backup thoughts - discussion starter

    Hello Everyone, This could be TL;DR I use Proxmox from the very beginning and I use ZFS for ages back when I had to compile it by myself and official PVE did not support using ZFS. I use smaller clusters (2 - 6 nodes, but a cluster is a cluster in case of 3+ nodes, so, if you see one, you saw...

    Avoiding fixed IP limitation from pve-zsync

    I've been playing with pve-zsync to backup my datasets and I was quite happy, but the fixed ip limitation was a boomer, because its almost the cost of another fiber connection just having to pay for a fixed IP. So one of my problems was changing the ssh port for security reasons and I've found...

    pve-zsync für zfs-Datasets

    Hallo, ich habe 2 PBS-Instanzen im Einsatz und synce sowohl Backups von VMs (blockbasiert), als auch Client-Backups (filebasiert) zwischen den beiden Servern mit dem "Remote"-Mechanismus für Datastores. Das funktioniert gut. Leider eignet sich der Proxmox Backup Client nicht besonders gut für...

    pve-zsync for VMs with multiple hard disks

    Hi support, I just set up a pair of standalone PVE servers that utilize ZFS storage. I'm using pve-zsync to create ZFS snapshots of the VMs and replicate them from one PVE server to the other. It's worth mentioning that one of the VMs is comprised of several large virtual hard disks (64 TB...

    pve-zfsync and MySQL inside the synced VM

    I try to use pve-zfsync to replicate a VM, and so far it looks quite good. The VM itself is a Cenos 7 with nginx/apache/mysql web site server. My concern is, while data VM disks will be replicated nicely, the data in the VM's RAM (mostly MySQL data) won't be transferred so the replicated VM may...

    pve-zsync: recovering VM?

    Planning to implement pve-zsync to do regular (routine) off-site VM replication, and it looks like I understand all my backup steps but can’t figure out the recovering steps: It says, first, I need to disable the replication for VM. Ok, that's understandable. Then, I can “send the VM or...

    [SOLVED] backup Storage pool

    Hello everyone, I tried to find information about this, but apparently my setup seems to be exotic in this aspect because no one else has done this. I have a small 2 node cluster and plan to add another node with PBS installed to back up all VMs and containers. But also: a whole storage pool...

    pve-zsync vs storage replication: differences in the internals

    Hello Proxmox Community! I'm digging into Proxmox internals (literally Perl scripts) a bit, but I can't find answer for my question: what's is the differences in internal implementation between pve-zsync and full storage replication task. As far as I can see both mentioned methods use ZFS...

    [SOLVED] VM mit pve-zsync migrieren | Volumes umbenennen?

    Hallo zusammen, ich würde gerne mehrere virtuelle Maschinen via pve-zsync migrieren. Nun habe ich das Problem, dass auf dem alten Host mehrere ZFS Pools existieren und die VMs Disks von mehreren Pools nutzen. Das sieht dann z.B. so aus: SSDTANK/vm-101-disk-1 HDDTANK/vm-101-disk-1 Wenn ich...

    A question about pve-zsync

    Ok, maybe this is a stupid question, but I was wondering... pve-zsync syncs a snapshot of the zvol containing the VM virtual disk. But since this is done while the VM is running (unlike what vzdump does), isn't it possible that the guest filesystem is "frozen" while it is in some inconsistent...
