Super slow, timeout, and VM stuck while backing up, after updated to PVE 9.1.1 and PBS 4.0.20

I don't want to celebrate too soon, but after two days with PBS running kernel 6.17.4-2-pve, all the scheduled backups have worked smoothly.
In fact, it seems even faster to me. Let's keep our fingers crossed for the next few days...
In the meantime, Merry Christmas to all the Proxmox staff and to all of you!

We finally see the light! :cool: Merry Xmas to everybody.
 
Are these upgrades mandatory in order to retain paid support, or are they optional? Stuff like this makes me really hesitate to commit to a product. I'm very much in the old school mind set that 'if it ain't broke, don't fix it' and surely major security issues would be stopped with correct Firewall setups..?
