Thank you for that example, I‘ll stick to the „hacky“ way suggested by oversite as I can easily change owners for all Backups at once. But good to have nonetheless!

How I understand it: The first backup kinda has to be a full backup, that makes sense. But the incrementals aren’t your traditional incrementals where the first „state“ of the VM never changes. PBS just keeps the chunks it needs for the last X days you specified. If you reached the prune...

Hi, I wanted to switch to a new datastore (store02) (on different disks) so did the following: Add a second datastore to the pbs server (store02) Added a remote with localhost and the store02 datastore Ran a sync from store01 to the "remote" localhost:store02 Removed store01 Modified the...

Hello, I was wondering if using the compression feature on ZFS Pools is worth it. The press release of PBS states the following: And in Proxmox you can enable ZSTD compression. Usually compressing already compressed data doesn't really work that well and just creates overhead, has someone done...

Hi, To understand why this is not done on every Backup and why it verifies old backups again you have to understand what „Verify“ does: It calculates hashes of all chunks and compares them to what they were when getting backed up first. This helps to find bits that flipped or are rotten just...

Hello, let's start with the following scenario: I created a VM with Windows and ID 110. The VM is backuped by PBS with a pruning of keep-daily=7. I no longer need this VM and decide to delete it. When deleting the backup does not automatically get deleted as well. Question 1: If I waited 7...

Hello, I wanted to know what permissions I actually have to give to the PVE-User to successfully backup to a datastore. What permission"path" does the user need and which role for that path? Dont want to grant a / superadmin if not neccessary. Did not find notes related to that in the...

What you can currently do: Restore the Machine as a second VM (aka click on datastore->contents->choose backup-> restore and dont hit the backup tab in the vm which would replace the VM) and make sure it is stopped. Follow the instructions on this page to move the drive to your old machine...

Are you up-to-date with PBS? It looks like it is issuing a fs-thaw command successfully

The backup calls a fsfreeze and fsthaw while snapshotting. can you check the logs if it successfully did a thaw on the machine or if it timed out?

I was having a bit of a brainfart, the disk format of course is the same for whatever storage backend was used in the first place once backed up with pbs. What packages are needed for this to work btw? qemu-utils for the qemu-nbd, but what package provides the pbs format for qemu-nbd?

Is there a way to accomplish the same with a CPEH RBD Setup?

How do I do that? Tried adding a second drive to the VM and then restore with proxmox-backup-client restore vm/101/2020-09-18T09:16:53Z drive-virtio0.img /dev/vdb but that doesn't work

Hello, we are currently using eve4pve-barc for backing up our Proxmox Cluster but are interested in using PBS in the future. One feature missing (or maybe it is there, just well hidden and I didn't catch it in the documentation): Restoring a disk without replacing the original drive. Sometimes...

Hello, I just set up a PBS and wanted to try it with my PVE Lab consisting of 3 nodes and CEPH storage at the latest version (6.2-11) I added my PBS Storage and started a Backup to my storeage with ZSTD compression, Snapshot mode. (All done via GUI) The task immediatly errors out with: ERROR...

That worked! Thank you very much!

Just tried booting an older Kernel, did not help. What I did notice though when I try to boot with the parameters cpu: host,flags=+hv-evmcs;+hv-vapic: vm 109 - unable to parse value of 'cpu' - format error flags: value does not match the regex pattern Did I mess up the syntax of the flags? I...

Ah ok, yes the module is enabled.

Its not the proxmox in the proxmox, that is the "parent" proxmox when I try to start a "children" proxmox. The conf file still exists. What do you mean by "modules are loaded"?

@James Crook I‘m on the same version as you but no luck so far.
