i wish i had a running site like yours!
Had the same issue with namecheap shared hosting, i lost a year of developing & have to start from scratch at

i got a tiny ass VPS with whm/cpanel
as webmaster:
You should have backed the server up! just tar & split into packages
Code:
tar cvzf - dir/ | split --bytes=200MB - sda1.backup.tar.gz.
