One thing still came to mind yesterday though:
Progress logging is now enabled unconditionally, and as is it is not 
possible to disable it or configure the interval.

So I plan to send a patch to make the progress log output opt-in, and 
make the interval configurable within a meaningful value range (maybe 
within 0s to 3600s?).

Something like:
```
proxmox-backup-client backup root.pxar:/ --progress-log-interval=10
```

And disable progress log output for a value of 0 or the optional 
parameter is not given.

That would also allow to more flexibly control the behavior when being 
invoked by vzdump.

What are your opinions on that?
