Ping is 50ms (offsite over internet) Yes, direct connection is faster, but still incredibly slow. BTW: The reasons I use SSH is: a) I dont't want to expose the GUI and the fact, that there is a PBS running. Also a complete UI-interface offers more attack surface. b) With SSH I get fail2ban and...

It is not sshuttle because the direct connection via port 8007 (even no VPN) is as slow as the sshuttle connection.

It is a good thing to have user data and the system on two different zfs file systems. Proxmox does it also. But there is no reason to split up the system data into 18 diferent file systems.

BUMP. Backup speed could be improved by factor 100-1000! https://bugzilla.proxmox.com/show_bug.cgi?id=3138

BTW: The Ubuntu ZFS-structure is really crazy. Lots of totally unnessary file systems, which make things really complicated. I looks like someone had the task to create as much file systems as possible. :-(. In my installations I tend to go the old way and convert an existing installation to ZFS...

The remote sync is very slow. It transfers only 0.4 MiB/s and takes 1h20min to transfer 2GB. See the log. 2020-11-15T09:50:18+01:00: sync snapshot "vm/101/2020-10-13T22:00:02Z" 2020-11-15T09:50:19+01:00: sync archive qemu-server.conf.blob 2020-11-15T09:50:19+01:00: sync archive...

1) I have an rpool ZFS pool and want to get this to boot (either with UEFI or grub). How to do this with a proxmox installation DVD? 2) How to change boot type from grub to uefi and vice versa (either in the workign system or with proxmox installation DVD).

The current design is not secure as it leaks information about the GUI. The remote syncing server also might have a dynamic IP the firewaling cannot be used to restrict access to one destination ip. Restriction to local users is also not possible. Local assords are often not as strong as...

Proxmox sends mails to the configured email adress, but how does it send this? How does it now where to send the mails (SMTP?)? Is there a cluster wide configuration is it per cluster member?

Please add this. https://bugzilla.proxmox.com/show_bug.cgi?id=3103

In PVE the default GUI language can be set by editing /etc/pve/datacenter.cfg. How to set the default langueage of PBS?

The current progress output uses bytes whih is very difficult to read. Example: progress 3% (read 3544186880 bytes, zeroes = 1% (54525952 bytes), duration 69 sec) Suggestion: Use Megabytes everywhere (preferred) or dynamic human readble numbers (K=Kilo, M=Mega, G=Giga) and/or use thousend...

ZFS is one of the main if not THE main filesystem used in proxmox, several things like replication, VM and container snapshots use ZFS functionality, so PBS should support this main usage in a fast and efficient way. The currently PBS is incredible slow on large containers, which makes it nearly...

I don't think so. If PBS would backup the snapshot (instead of the live filesystem) and would use "zfs diff" to detect all changed/added/deleted files, it knows which data changed and does not have to reread everything unchanged. Snapshots are also unchangeable to there is no possibility of any...

But "zfs diff" works at the file level, so if pxar needs to know which files changed it could determine it with "zfs diff".

So PBS currently not really usgable for large containers. In theory it would be possible to use "zfs diff" or parse the ZFS differential send stream to determine the differences. See zstreamdump.
