vzdump

It's all about time. The time server spent on doing backups. The time we spent on recovering files. So my three question: 1. Is this possible to do compressed backup without tar? Is tar really needed this days? 2. I think that tar is my bottleneck when doing backups (it uses only one core of...

Hello to the community, I was following this thread to find the solution to the problem, but I got different behaviour. My guest VM is using 13GB on /dev/sda1, here's the configuration bootdisk: scsi0 cores: 1 ide2: none,media=cdrom lock: backup memory: 4096 name: pippo001 net0...

Hi all is possiible make vzdump from created snapshot in QCOW2 ? Thanks in advance.

Hello, I have been trying to find a solution to this annoying problem for over six months. Have updated both servers (one is a community edition subscription and one is without subscription). This happens with both of them. Whenever I try to have an automated or manual backup of my VM (I don't...

Fellows, i`m running the backup of VMs one time at month thought console with the command: /usr/bin/vzdump <VM_ID> --quiet 1 --mode suspend --node <NODE_NAME> --compress gzip --storage bkp -bwlimit 51200 the backup always complete with sucess: 2018-02-25 00:15:02 INFO: Starting Backup of VM...

Hello everyone, I think (and hope) I have a relatively simple question: I have a container with a Jenkins installation which I'd like to back-up, but I don't want/need to backup the working directory. Is there a way I can set the vzdump exclude option for this container specifically? I tried...

I have a weird problem with specific containers failing to snapshot; the end result is that scheduled vzdump tasks effectively fail and disallow any further vzdump jobs until manually killed. The thing is, if I MANUALLY take a snapshot using rbd snap create it works fine- its only via api that...

Hallo zusammen, ich habe unseren Produktivcluster auf PVE 5.1 aktualisiert und habe seitdem ein sehr eigenartiges Problem. Ich kann keine Backups mehr erstellen. Genauer gesagt: Ich konnte nach aufsetzen des neuen Clusters in der Version 5.1 zwar lesend auf das nfs Target zugreifen und die...

Hello, I'm having some issues with a particular Proxmox 4.4 Server: sometimes prolonged power outages happen during VZDump operations, causing proxmox to shutdown, and so resulting in a locked VM which of course doesn't start at the next boot. Is there a way to automatically unlock VM at boot...

I'm trying to sort out the process for restoring vzdump backups taken on server A to server B. The steps I follow are: 1) Take backup with vzdump on server A. 2) Copy .vma file from server A to a NAS over CIFS. 3) Copy .vma file from NAS to server B over CIFS placing it in /var/lib/vz/dump/ 4)...

Just about every night I have at least one (sometimes more) containers with a failed backup; The status of task cryptically just says "32052: Oct 30 07:31:48 ERROR: Backup of VM 32052 failed - CT is locked (backup)" The lock isnt clears and remains so until manually cleared via pct unlock...

I've a VM on a disk with I/O error, I want to make backup of that VM while it's running, therefor it's not possible to use dd, Is that possible to ask vzdump to continue on I/O error of source disk?

I have a problem with a specific container hanging on vzdump jobs. It has a unionfs mounted file system and are a result the vzdump task hangs. The consequences of this is that no other backup jobs on that node can process until that task is cancelled manually. 1. Is there a way to control...

I'm using the suspend mode for my automated backups, but in order to decrease disk writes I would like to have rsync write it's temporary files to a ramdisk (tmpfs). Something like this: in /etc/fstab tmpfs /mnt/ramdisk tmpfs nodev,nosuid,noexec,nodiratime,size=32G 0 0 in...

I have a proxmox cluster. I migrated one of the containers from one host to the other. File system is zfs, pveversion pve-manager/4.4-12/e71b7a74 (running kernel: 4.4.40-1-pve) After that vzdump started to hang on INFO: create storage snapshot 'vzdump' If I try zfs snapshot...

I have a cluster with two nodes. The backups have been running fine. Recently I now get this error on a couple VMs on ONE node. write write error broken pipe. What does that mean? How do I fix that? I have rebooted the Failed VMs hoping that might cause the broken pipes to reconnect, but...

it appears that there is a fault in the job validation code in backup.pm. The offending code is: if ($job->{starttime} =~ m/^(\d{1,2}):(\d{1,2})$/) { ($hour, $minute) = (int($1), int($2)); die "hour '$hour' out of range\n" if $hour < 0 || $hour > 23; die "minute '$minute' out of range\n" if...

This issue has been with us since we upgraded our cluster to Proxmox 4.x, and converted our guests from OpenVZ to KVM. We have single and dual socket Westmere, Sandy Bridge and Ivy Bridge nodes, using ZFS RAID10 HDD or ZFS RAIDZ SSD arrays, and every one of them is affected. Description When...

Wen backing up some KVM guests from ZFS to NFS, vzdump gives the following error: As you can see it takes exactly one hour until vzdump tries this freeze and fails many times, after that the backup completes in normal time. It only happens to a few VMs, most of them are not affected. Any...

Hello, I found that my VM dumps are bigger than the used disk space inside my VMs. I made some searches and found this is because removed files from the disk are just flagged to be deleted but not removed from the disk. I understand that. I found that I can zero-fill my free space with dd, but...
