I'm putting this here for anyone else who has this issue:
Basically:
Format the SD card you are restoring to.
More Detail:
I got this issue when trying to restore a backup to a smaller SD card to the original SD card the backup was taken from.
That SD card was previously used for a boot SD card in the RPI.
Tried again with a larger sd card (Didn't have another 32GB card) and it worked as expected.
Trying to restore to a smaller SD card that was previously used for RPI boot SD card:

IT WORKED
Mac OS -> iTerm -> SSH - > RPI runing Buster
/dev/sda is a USB stick where I backup to / restore from
/dev/sdba is the SD card I'm restoring to

Ok, when I connect via SSH with the gnome-terminal it works fine. I see the "Are you sure? y/N" question, can confirm and the script starts the restore. So there must be an issue with putty I guess (the error mentioned above is reproducible each time when I connect from a windows machine with putty).

I have no idea what's wrong. I have to have a Windows Handy in order to reproduce the issue. Will try to find one

Just found sombody still using Windows :-D. I was able to successfully restore a backup via putty. I ran raspiBackup on raspbian stretch. Which OS do you use? Maybe this makes the difference.

@phars If this is still an issue please provide more details how I can reproduce the issue.

Sorry, didn't have the time to investigate further. For me it's not that critical since I do not use my windows machine very often. Thanks anyway!

@Jakst3r Thank you very much for the analysis and a workaround description. I will try to recreate the issue when restoring to a smaller SD card. If you still have the restore log handy please provide the log which may help me to identify the root cause for the issue 😉

Not a problem 😊 Not anymore as it was overwritten on the successful restore after formating the card.
I tried to restore onto a 32GB SD card with a previous Buster install on and it appears to work as expected.
I don't have an 8GB SD card (I'm currently running on my 16GB)
Next time this happens il be sure to keep the log and upload it though.
@framps please let me know if there is anything else I can do to assist.

I just tried to reproduce your issue with the same code level you used. Unfortunately I failed 😞

I used a different smaller size than you (4GB vs 16GB) but nevertheless the same codepath is used.
That's my environment:
sudo lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 279.5G 0 disk
└─sda1 8:1 0 279.5G 0 part /backup
sdc 8:32 1 3.8G 0 disk
├─sdc1 8:33 1 256M 0 part
└─sdc2 8:34 1 3.5G 0 part
mmcblk0 179:0 0 7.5G 0 disk
├─mmcblk0p1 179:1 0 256M 0 part /boot
└─mmcblk0p2 179:2 0 7.3G 0 part /
The code which seems to hang is here
Looks like parted hangs for some unknown reasons...
I keep this issue open. If somebody faces the same issue please report the issue and we'll try to isolate the root cause.
