The mount man says: (in the Ubuntu 18.04)
Disable/enable the discard mount option. The discard function
issues frequent commands to let the block device reclaim space
freed by the filesystem. This is useful for SSD devices, thinly...
Running fstrim, the backup procedure reads the entire disk, but does not copy the deleted data.
Using the configuration below, the backup reads only the blocks from the deleted file and does not copy them to PBS. \o/
S.O. Ubuntu 20.05 (kernel 5.4.0-65)
So by default the image backup procedure will transfer the modified blocks to the Proxmox Backup Server (PBS), even if the data within the file system has been deleted.
However, if I run fstrim, the backup procedure will read the disk again (this also happens when I turn off / on the vm)...
I realized that even excluding files, before the backup is performed, these files are counted and backed up.
This is not good, especially when working with large files.
The problem can be easily isolated and reproduced
1. Create a new virtual disk on a virtual machine
Timeout set for 60 seconds:
- The server view 'tree' is not updated, but the status: unknown error does not appear
- After some time, the same problem occurs
When having to disable the metric server, the following error is displayed:
This problem occurs only when the graphite is unavailable. When it is accessible, the problem does not occur.
From my point of view, the metrics server is not accessible, it should not cause a problem in the visualization of the status of virtual machines through the Proxmox interface.
Even restarting services, the problem remains.
I can resolve it when I disable the metric server, but to disable it through the GUI, it must be accessible.
Should I open a BugReport on this? Anyone else with the same problem?
This problem occurs only when the metrics server is unavailable.
PVE Version: 6.3
proxmox-ve: 6.3-1 (running kernel: 5.4.73-1-pve)
pve-manager: 6.3-2 (running version: 6.3-2/22f57405)
In some scenarios it is important to limit the internet bandwidth occupied by the task of synchronizing backups between two 'Proxmox Backup Server'. Is this possible today or is it possible to implement this feature?
Looking at the roadmap, they intend to include this function in the future. (https://pbs.proxmox.com/wiki/index.php/Roadmap)
In my home lab, this command worked to back up the Proxmox Host

It's great to have a complete open source, cost-free hyperconvergence alternative, especially if you look at the values of VMware (Vsan) and Nutanix.
I already set up an experimental setup with Proxmox and Ceph in a test lab, including posting a video about my experience...
