HI

 

Im a new member but spent many many hours/days setting up/configuring and using DSM as a VM on Proxmox host.  Now I' working on the best strategy for Backing up my DSM vm to protect against a system failure, be it Proxmox failure or a DSM unrecoverable problem.  I have searched this forum and the web for best solutions and am posting this to ask for guidance.  Thanks in advance!

 

System: 

Minisforum m-01 i9

Proxmox 8.3.3

DSM 7.2 via ARC installer

 

I have Proxmox Backup Server installed and backing up all other VMs.  It will not BU my DSM vm.  Ive also tried direct BU via Proxmox PVE to its dedicated storage or an external drive.  Again, trying to BU the DSM vm fails.

 

  1. Has anyone found a way to backup the DSM vm via Proxmox or its Backup server?
    • if not, is there a known reason this doesnt work?
  2. Does Synology ABB and/or Hyperbackup work to BU the full DSM if I create a 2nd DSM VM to receive the backup?
    • If not, is there a known reason?
  3. Would a good option be to make a disk image of the Proxmox (with DSM and other vms) nvme and use that image to restore everything?  Should that work?
    • If so, any suggestions for a user-friendly, hopefully GUI based, imaging tool for a Linux novice?  I imagine this would be some "live CD/USB" to boot the hardware from?  Other?

 

Above are the solutions that come to mind, but likely others know the real best options??

 

Any help (again for a less experienced Linux user), would be really appreciated 

 

Thanks!!!

Hi! From my Proxmox Server I can backup my DS VM using integrated backup function and I can restore it without any issues. It copies both the loader and only the virtual disk drive if it is in the configuration of the VM. I use i18n and newly RR loader. I also have a backup copy of the Proxmox installation and I used Disk Genius, it has a PE environment. Never encountered any problems when I use save to image file in data mode, not file mode. I think it helps if you try to be more specific like post images or logs 

 

The loader, by default, is in the /var/lib/vz/template/iso folder, but you may have other storage location and the loader may be located somewhere else. If you look at the VM's configuration file (vi //etc/pve/nodes/*you-pve-name*/qemu-server/100.conf) you may see the location, but I think you already know that.

Thanks @blindspot  Its good to know that I SHOULD be able to use BU directly in Proxmox. Now that youve verified this SHOULD work. I will follow-up this weekend with more details to troubleshoot why is isn't working for me...

 

Thanks

HI @blindspot

 

I now have Proxmox BU server working in backing up my DSM vm.  Im not sure what the issue had been, but it seems to be resolved now.  Thanks for confirming it should work so I could reinvestigate.

 

I'll follow the other references you made about Disk Genius and about looking for my DSM loader file...  Thanks for those updates to your post.

 

Another option I have heard is Veeam free version, which I believe also can work with Proxmox. I will be looking at that too...

 

Thanks
