It sounds like snapshots are directly reachable from within FTP in a directory. Snapshots are a clean copy of the file system you can back up, but they are not backups.
He also states he has his backups, so he's mostly just whining because he's annoyed he has to reupload stuff. Which I get, but again, he should understand what snapshots are and aren't.
Interestingly, this page has been edited to add a warning: "A snapshot is a frozen version of your volume that allows you to restore it to a previous state. It should not be regarded as a backup of your volume. If your volume is deleted, all related snapshots will be deleted too."
As @dwild stated, that's the other type of snapshots used for web hosting (which I assume are copy-based backups due to how little storage sites usually use). These snapshots are never reachable directly to the customer; at best, they can restore a volume back to the snapshot's state or create a new volume at that state and attach it to a VM.

Or they're annoyed that they paid for a service, at the very least billed as backup, only to be told "welp, it's gone".
