    LXC Containers Backing Up Incredibly Slow

    I want to backup whole LXC into PBS as fast as QEMU. Is there any option to do ZFS snapshot based backups to PBS?

    LXC Containers Backing Up Incredibly Slow

    @fabian is there any hope that Proxmox team will implement zfs block backend backup metod (zfs send|zfs receive) when using zfs storage with PBS?

    LXC Containers Backing Up Incredibly Slow

    @fabian any solution for backuping very big lxc with milions of files?

    LXC Containers Backing Up Incredibly Slow

    I clearly understand the concept of being agnostic and agree this approach. But from other side: Proxmox recommends ZFS - so IMO work with ZFS should be done with native ZFS tools.

    LXC Containers Backing Up Incredibly Slow

    @fabian If You got >10 milions files rsync doesn't work well (with expected performance - any file-based-tool won't). Default storage agnostic procedure is OK - but for ZFS we got much more better options. If we use ZFS on both sides: - Proxmox->PBS for backup, - PBS->Proxmox for backup...

    Different IP addresses for different SMTP servers/domain

    Got a case when: one PMG is a gateway for 3 SMTP servers (all of them are iredmail). Each of server is dedicated for other company. Problem: One of SMTP server could make mail-exchange blocked for others. How? Imagine situation when IP goes to RBL. Resolve: I would like where mail exchange...

    LXC slow migration workaround

    This was second main thing that I jumped out to ZFS stack from LVM. So for ext4 we should use "lvmsync" and for ZFS "zfs send/recv".

    LXC slow migration workaround

    In this example I got two remotes VPS1 and VPS2. In the past when the container was <500G I was using rsync and backup/restore method. Now when the container has almost 2TB. I am not able to migrate this container with resonable downtime. So for workaround I did: # example1: initial replicate...

    Preferred Method to Make ethtool Changes Persistent Across Reboots and Updates?

    Its better to set many changes at once: This: pre-up ethtool -K $IFACE rx-checksumming on pre-up ethtool -K $IFACE tx-checksumming on pre-up ethtool -K $IFACE tx-checksum-ip-generic on Could be: pre-up ethtool -K $IFACE rx-checksumming on tx-checksumming on tx-checksum-ip-generic on Good...

    backup speed for LXC with ZFS backend

    I know that difference but in backup process incremental snapshot using zfs send / zfs receive time is also the same. Maybe PBS/PBS Client dev should use other magic spells for backuping LXC?

    backup speed for LXC with ZFS backend

    Well - doing incremental backup I see that comparing backups VM(1TB) and LXC(800GB) speed there is 10x performance gap (or even more! - doing backup for LXC is significantly slower even if it's smaller) I did some test zfs send/zfs receive to remote host not differs so much. Local storage...

    [TUTORIAL] Proxmox ZFS raid1 performance

    Sorry. Dictionary in my Phone made bad things sometimes. I mean PLP technology - capacitor on SSD Drive. That allows to scream by ssd "write done" before it is done because it save. Check pvestat command on both drives.

    [TUTORIAL] Proxmox ZFS raid1 performance

    Most important if You use ZFS: buy SSD with PLOP (performance 2-2.5x !!!)
