In https://forum.proxmox.com/threads/abysmally-slow-restore-from-backup.133602/page-7 we have discussed some other opportunities for speedup using similar patterns. People mentioned LXC container restore speed and host-based backup restore, which looking at the code for the latter seems like a similar async loop pattern would bring some improvement without too much trouble: https://github.com/proxmox/proxmox-backup/blob/4940514b0f05d6cd6a5f711edfdd47c1fa41b537/proxmox-backup-client/src/main.rs#L1109 Similarly the sync performance between two Proxmox Backup Servers and live-migration got mentioned in various places. Btw. congrats on the 4.0 beta.
