Preface
While I am basically sure this is documented somewhere I was not able to find a compact guide. And I was never in a situation where this was necessary... yet. What I had found is https://pve.proxmox.com/wiki/VMA and the man-pages of the required commands, but no “walk-through”...
My linux VMs back up fine, but the windows ones do not. I was using zstd and the backups kept freezing (I couldn't stop the process without restarting the node), so I am trying gzip now. This time, the process at least ends without hanging, but there are still errors on the windows VMs.
I'm...
I'm trying to send a VM backup to a S3 bucket that has been mounted to a local file. I have succesfully backed up to this mounted share directly from proxmox with a ~25GB disk, but fails on a ~125GB disk.

Hi.
I'm currently doing some tests with Proxmox and TrueNAS (both on dedicated machines connected via 10gbit) and looking at the Proxmox backup function got me thinking:
Would it make any sense to send uncompressed Backups to a TrueNAS volume with ZSTD compression (instead of doing the ZSTD...
I know I can use zstd: N and I have BWLIMIT: 49152 set in /etc/vzdump.conf, but I am not sure zstd takes bwlimit in consideration. the process executing the back shows ... cstream -t 50331648 | zstd --rsyncable '--threads=2' ...
I need to lower the bandwidth bc it's straining the disk and...
In one of my server I frequently run into failed backups on a CIFS location and since this is the case for several month now I thought I start a new thread, also there already is this old thread from another user but probably with a similar problem.
What I can say for sure is that this is not a...
We run proxmox 6.3-3. A scheduled backup fails for a single VM with:
...
NFO: 59% (2.4 TiB of 4.1 TiB) in 5h 37m 20s, read: 124.1 MiB/s, write: 122.1 MiB/s
zstd: error 25 : Write error : File too large (cannot write compressed block)

i have lxc containers hostes on ceph storage (with speed over 5GBs )
when making backup using zstd the speed is between 20-90MBs
the storage i am writing to store the backup have read/write speed around 1GB
proxmox 6.2.12
on some hosts the ZSTD backup compression is not working?
any idea why ?
this is the error?
Parameter verification failed. (400)
compress: value 'zstd' does not have a value in the enumeration '0, 1, gzip, lzo'
solution:
upgrade proxmox to latest version on all nodes.
