Migration from SD Card to SSD. How long to restore backup

How long takes full backup restore?
I ma trying to migrate from SD Card to SSD with Argon Case and Rpi4.

Before I installed SSD I created full backup and download it on PC.
I took SD Card off and install SSD with HA image on it.
I created user and upload backup to HA and pressed Restore - Full Backup.
I lost connection and after 3 hours HA is still not available.

Backup file is 1.2GB.

I noticed something else. When I swap to SSD I do not have HDMI output. TV is showing no signal (with SD Card it was working normal.) so I can not see what is happening there.
