How to save backup cisco config via https and to what hosting?

Question

Cisco

I save configs when rewriting Cisco 881 to FTP:

archive
log config
logging enable
hidekeys
path ftp://ftp:[email protected]/cisco/$h-$t.txt
write-memory

I want to get away from FTP in general, the path command has the ability to save to https, but I can’t find a description of how it works. and for one thing on what (preferably free) hosting can you save like this?
