Backup/timeout issues PVE 6.4

[Eneko Lacunza]

Hi all,

We're having backup/timeout issues with traditional non-PBS backups in 6.4 .

We have 3 nodes backing up to a NFS server with HDDs. For the same 
backup task (with multiple VMs spread in those 3 nodes), one node may 
finish all backups, but other may not be able to perform all VM backups, 
or not even start them due to storage "not being online".

Version (the same for all 3 nodes):

proxmox-ve: 6.4-1 (running kernel: 5.4.162-1-pve)

Is this a known bug? We had some issues in another cluster that fixed 
using this patch on v6 (applied manually):
https://bugzilla.proxmox.com/show_bug.cgi?id=3693

Has that bug been backported to v6?

Thanks
