restore

is there any way to do a restore from a specific remote location without having to download first,

example, i had backups on Dropbox, DB uploaded on dropbox was corrupted, so when i went to restore, the restore fails, luckily i had a server backup as well, so just restored that, but relying on a single point of failure seems a really bad idea, so i have now added, dropbox, FTP (box.com), DreamObjects & Rackspace, so I now have 4 copies, so theoretically, we should be safe unless of course the corruption happens before the upload, but this leads to a new issue, when doing a restore, there is no way of telling where to restore from, so if DropBox was corrupt, i would still need to login manually to one of the others and find and download the relevant zips then upload, but this is a major issue with near 200 sites we are moving from codegaurd  and 60 day retention policy, finding that one file is going to be a headache at best.
