Thank you. Your explanation, regarding this topic, is the best I've read so far. @Dunuin Both actually. This NTFS external drive is plugged into a (non-proxmox) Ubuntu 20.04 server. Even though the drive is external, it is mounted via fstab with the following line...

@Dunuin Thanks for the reply. I don't understand what is so special about privileged or unprivileged LXC containers, that they cannot be encapsulated into a file that gets transferred to a NFS share in the same manner as all other backups! In my thinking, a backup is just a file that contains...

I've never encountered anything like this before. Typically, any sender will not send any faster than what is acknowledge by the receiver; the sender simply sends as fast as can be received and no faster than that. The TCP protocol has built-in features that regulate this type of thing. Also...

The VM disk are virtio, as shown in the screenshots above. For the backup target, I'm using an Ubuntu 20.04 NFS share, running on a intel core duo, with an enterprise hard drive that has plenty of free space. These types of backups succeed when compression does not equal none. Why would simply...

Are you talking about the log you see in the Web interface during backup? There were two of these. The first is from the "snapshot mode backup", where I was able to successfully stop the backup. The 2nd is from when I tried a "stop mode backup", where I had a failed attempt to resume during...

The attached log.txt starts 17 minutes prior to backup. @fabian

In Proxmox 7, I attempted to do a "snapshot mode backup" with compression set to "none". During the backup, the Virtual Machine was completely inaccessible and none of its services worked. Also, I attempted doing a "stop mode backup" with compression set to "none". During the backup, I hit the...

I upgraded from Proxmox 6 to 7, by doing a clean install of Proxmox 7, mounting NFS shares, and then restoring all backups. Now, I too am getting the same error talked about in this post: https://forum.proxmox.com/threads/create-backup-fail-with-error-cannot-open-permission-de.32386/ INFO...

Thank you. I didn't know that! However, if I were to extract the disk images and config blogs using the vma binary, would it extract those things as files? If so, I still hope VMA evolves to become a package in the repositories of all distributions, just so that I can use popular tools like...

Thank you for addressing my concerns. After reading the Technical Overview, I can see how Proxmox Backup Server is likely the most efficient option available (both locally and remotely). Proxmox to NFS local backups have to transfer the whole backup file to NFS for each backup. If I'm...

I was just reading about this today. From what I understand, installing PBS at the remote location, alone, wouldn't lead to efficient network transfer of remote backups. There would need to be a local install of PBS, and another installation at the remote location. Then, from the remote...

In your testing, were you backing up LXC containers exclusively? In Proxmox 7, (by default) LXC containers backup to tar.zst, while KVMs backup to vma.zst. No-Compression backups of KVM produce a .vma file. I read that VMA files create a large diff. In your testing, were KVM backups included...

Thankfully, I noticed that the LXC containers still backup using tar.zst in Proxmox 7. I'm able to open those with Ark, in Kubuntu 20.04, by simply double clicking them. I think the reason I'm able to do this is because I've install zstd in the past: sudo apt install zstd When I double-click a...

It seems like there should be a compression file-type, in existence, that places priority on limiting the unnecessary variances that occur in succeeding backup files. If such a compression file-type exists, I'd like to see it get added to Proxmox. In the meantime, I'll have to endure what is...

I just realized that I've asked this question before: https://forum.proxmox.com/threads/which-proxmox-backup-compression-is-best-for-rsync-fuzzy.70975/

Which backup file-type has the least variances between backups? For example, lets say I have a 200GB virtual machine that I backup today using zst and I move that file to a remote location. Tomorrow, If I backup this same virtual machine again, using zst, and then use rsync (--fuzzy) to sync...

Which memory mode is best for Proxmox on a Dell PowerEdge T620 server?

I have a Dell R515 server that I upgraded so that all 8 hard-drives are solid state. Specifically, I have 8 of these SSDs in a RAID 10: Samsung V-NAND SSD 860 EVO 1TB SATA 6Gbps Model MZ-76E1T0 Model Code: MZ-76E1T0E After a few months, Proxmox kept emailing me this error regarding...

Proxmox provides 3 options for backup compression: LZO (fast) GZIP (good) ZSTD (fast and good) Which of these 3 would be most efficient for "Rsync --fuzzy Synchronization", which uses a previous backup at an offsite destination as the basis for minimizing data transfer of the most current...
