Every time I upload the archive, snapshot proceeds to create a new backup on top of it

I had to reinstall a server and I'm currently trying to restore from a week old Snapshot image. But every time I upload the archive, snapshot proceeds to create a new backup on top of it (the snapshot was configured to run at weekly intervals) Would you be able to assist? I'm trying to restore on a local WP installation and then using All in one migration to move it over to my new host as I'm having issues doing a restore directly on the host and I do not want to eat up on bandwidth (have uploaded the 500mb archive 8 times now and that's about 4Gigs of transfer down the drain)
