I mean if I backup from BTRFS can I restore it into ext4 ?
Your backup software neither knows nor cares how your filesystem is formatted, so of course you can. Unless, of course, you're cloning the partition, in which case a restore will overwrite the partition with the original formatting.
I'm pretty sure Chris was correct. You system is set up to boot from the btrfs file system -- not ext4. Changing the file system will result in needed changes in boot loader, fstab, etc.
Restoring to an ext4 file system will not result in a bootable system.
How does this sound?
I make a complete tar backup of my system.
Reinstall F33 to ext4.
Restore that tar, of course fstab and crypttab needs to be corrected.
Will this work? Does it make any sense?
So will this work ? Any feedback ?
Probably not because it'll step on valid bootloader things with stale copies. If you avoid stepping on anything in:
/boot /etc/grub*
It might work... but you'll still have kernels that rpm database says are installed that aren't installed; you'll have stale boot entries for kernels that aren't installed and thus won't work. None of it will get cleaned up on its own.
