  1. zfs-autobackup / freenas / Replikation

    Hallo, ich habe angefangen mich mit zfs-autobackup beschäftigen. Ich nutze im Augenblick eine Freenas und die Snapshot dort mit zfs-autobackup zu speichern, das geht natürlich auch mit andere ZFS Systemen. Nun nutze ich dem der Replikation über die Proxmoxgui auch noch zfs-auto-snapshot und...
  2. 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...
  3. 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...
  4. [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...
  5. 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...
  6. PVE-Zsync and local backup: Backup different disks

    Hi! I have a proxmox VM with Windows Server and 3 disks, setup is as follows: Disk 0: OS disk – 200Gb - Backup enabled on proxmox Disk 1: Data disk – 1,5Tb - Backup enabled on proxmox Disk 2: Other Windows PC backups – 1,5 Tb - Backup not enabled on proxmox Currently I have a USB harddisk...
  7. [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...
  8. 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...
  9. vzdump+zfs - Böse, Featurewunsch: pve-zsync in Web-GUI

    Hallo, hoffentlich ist hier der richtige Bereich dafür. ich habe einen einzelnen PVE Server und habe seit kurzem massive Probleme beim erstellen von Backups. Bisher habe ich (klassisch) über die GUI ein vzdump Backup-Job (nächtlich) erstellt. Leider führt das in bestimmten Konstellationen zum...
  10. pve-zsync sync from one node to several nodes

    Hi there, Apologies if this has already been answered somewhere, I was not able to find a conclusive answer. I have several nodes in my cluster. I use zfs-autosnapshot because I want to have 'point in time restore possibility'. I have a conflict zfs-autosnapshot with pvesr. For example: pvesr...
  11. pve-zsync issues

    Hi, I have two servers running proxmox 5.3-6. Both run several VMs and I am using pve-zsync to sync two machines in server1 in server two for disaster recovery and offline backups. This has been working without issue with two proxmox servers running 5.1-46. I have just replaced them with...
  12. two pve-zsync's to backup the same machine

    Hello, is it possible to use pve-zsync on two different hosts to backup the same (third) machine? i.e. like this: - pve-zsync on host B fetches a backup of VM101 from host A - pve-zsync on host C also fetches a backup of VM101 from host A ? Thanks
  13. [SOLVED] pve-zsync Ausgabe: can't parse options

    Hallo, seit heute Morgen erhalbe ich folgenden Fehler: root@pve01:~# pve-zsync list Option s is ambiguous (skip, source, source-user) can't parse options Ich habe natürlich nichts gemacht, vorher... ;-) Im Ernst, ich habe versucht die Ausgabe des obigen Befehls an eine Mailadresse zu senden...

  15. recovering a pve-zsync installation after a crash

    I have "server1" (10.0.0.1) backing up VM 502 on "server2" (10.0.0.2) with pve-zsync. I set up the process with: server1# pve-zsync create --source 10.0.0.2:502 --dest rpool/pve-zsync/daily --verbose --maxsnap 7 --name server2-backup-daily eventually, server1 blows up and I have to completely...

  17. how to disable cronjob e-mail alerts?

    hello I have configured e-mail alerts on the pve hosts and they are successfully being sent to the root account (which then forwards to my real e-mail account). What I’m trying to figure out is how to disable e-mail alerts sent by cron. If that’s not possible, can I somehow disable only zfs...
  18. pve-zsync update enhancement

    This is an easy one (well, maybe). Recent versions of ZoL (zfs on linux) have added the previously-missing zfs send | receive option to send a pool with its compression intact. That is to say, send the data in its compressed state. This is the zfs send -c option. I am currently using...
