  2. Backup Server too slow, IO on VM stalled during Backup

    Hi, I have a setup at a Hoster where the Proxmox VM Server is damned fast using NVMEs and the Proxmox Backup Server is terrible slow, for example network Bandwidth sometimes is only 30 MB/s What happens now: The Backup ov VM starts really fast with let's say 500 MB/s reading speed. The Proxmox...
  3. To cluster 2 pve Servers at my Hoster or not ?

    A customer has 2 Servers at Hetzner in 2 Different IP subnets and in 2 Different Datacenters and asked me to modernize them. I would install a proxmox pve distribution on each server. Does someone have experiences if it is a good idea to cluster the servers in a pve cluster ? I could easily...
  4. How to run redundant read only copy of Proxmox Backup Server

    I have a Proxmox Backup Server in Data Center and would like to have a copy in another location. Proxmox Sync is no option, there is not enough online Bandwidth Tape also is no option, we will not invest again in tape technology I am taking a differential zfs snapshot on harddisk from...
  5. Replicate Backups to Offsite on media instead of online ?

    I have a Backup Server with around 30TB of Backup Data. I would like to take all Backups offsite once a week. Unfortunately the daily change of Backup Blocks are so many that we cannot replicate them online. I mean it would be complete overkill to have a 10 GBit/s Line only for replicating...
  6. Scripted export of latest Backup image file possible ?

    We would like to regularly keep backups of Data outside of the Building. The full datastore including history of all Backups of all Machines does not fit on external disks and is too much for Internet syncing. I would like to somehow export the latest image of each vm once a week to an external...
  7. Speed up Backupserver by adding zfs special device ?

    I like proxmox backup server but budget only allows magnetic disks and raidz2. So especially verify and garbage collect procedures need a hell of a lot of time. For an 8 TB Backup space today verify needs 2 days and garbage collect needs 1 day. I think with verify there is not much i can do...
  8. [SOLVED] Restore vm to new vm-id ?

    Is there a way in proxmox Backup Server to restore an image backup to a new machine ? I would like e.g. to restore backup vm/100 to vm/101 ? In some situations it is impoortant to keep vm/100 up and running
  9. Any Hints why my incremental Backups are way too large ?

    We are still evaluating pbs Server and begin to like it more and more. One problem ist that on some Servers e.g. mailserver or lamp server the incremental size ist unbevlievable high. An incremental after 24 hours is about 50% of the initial Backup size. But with a find-command run i find only...
  10. Proxmox Backup Client extremely slow on large Mailservers ?

    I have a Mailserver with 500GB of E-Mails in 40 Mio Files in Maildir Format. When I backup the Mailserver with traditional tar/amanda it takes around 35 Minutes to do an incremental file backup the Server When I backup the server with proxmox backup client it takes hours to backup the...
  11. proxmox-backup-client for windows ?

    Hi, how realistic is it to have a proxmox-backup-client for windows in the next months ? Is someone working on that ? Would that be an easy or complicated task ? I would like to have file Backups of windows vms in addition to image Backups.
  12. VM Crashes during backups when using qemu-guest-agent

    Hi there, when running backups on vms which have qemu-guest-agent enabled the vms will regularly crash. This seems to be a well known problem with qemu guest agent which is described like this: When VM backup is invoked, Qemu agent freezes the file systems, so no single change will be made...
  13. Backup too fast/Clear Backup Cache ?

    Hi, today i removed my former proxmox-backup-server (vm) and changed the clients to make their host-backups with proxmox-backup-client to a newly installed proxmox backup server (hardware). The Backup of the 50GB Filesystem of the client finishes in 2 Minutes. I am absolutely sure this is...
  14. Monitoring Proxmox Backup Server

    Hi, i am thinking about implementing some nagios checks for the proxmox backup server. I would like to check that the last datastore verify was successfull and not older x days Also I would like to check that the last Garbage Collection and Pruge was successfull Also maybe that the last file...
  15. Naming backups from proxmox-backup-client

    I just tested proxmox-backup-client on a client named web1 and i noticed that the name of the backup in the datastore was "web1". Since I have many web1 i wonder how I could give the backup set a more descriptive name ?
  16. Scheduling proxmox-backup-client from backup-server

    Hi, i am just evaluating proxmox backup server and I am really impressed. But how can i schedule client-file backups from the server so that for example only 2 or 3 backups run at the same time ? Lets say i have 80 vms to backup and my resources like cpu or disk or network only allow for 3...
  17. Ceph: read/write statistics per RBD image

    Hi, i would like to retrieve ceph read/write statistics per rbd image on my proxmox cluster. I am trying to configure the admin socket for client.libvirt like in this url http://docs.ceph.com/docs/luminous/rbd/libvirt/#configuring-ceph but I never manage to get the admin sockets created. Did...

  19. ceph osd performance is 0 0 in proxmox 5 gui

    Hi, since I updated my proxmox from 4.4 to 5.0.30 the performance counters apply/commit in the ceph gui under osd always show 0 0 instead of true values. The command line equivalent ceph osd perf shows realistic values. I have cleared brwoser cache. I am using the original ceph luminous...
  20. Can I keep original ceph.com repositories ?

    Hi there, i am running ceph lumious on a proxmox 4.4 cluster and i am very satisfied with the original 12.2 ceph packages from ceph.com . Now we are planning to upgrade to proxmox 5.0. The proxmox upgrade guide explicitly says: Replace ceph.com repositories with proxmox.com ceph...
