Guidelines

1. Don’t put projects in the same folder with backups.
2. It's wise to put them in a cloud folder and/or sync to an external drive.
3. Any cloud service is fine for zip files.
4. Literature & Latte recommends Dropbox over other cloud services.
5. Dropbox is the only way to sync from PCs, Macs to iOS Scrivener.
6. NO cloud service is 100% free of glitches.
7. If you have problems, a recent zip backup is likely to be safer than an uncompressed project, no matter where they're stored.

Example Setup

Below you see where my wife and I keep our projects and backups. Her projects are in the default location for sync to iOS (iPhone and iPad) Scrivener, but mine are in a different folder.

Using different folders keeps us from wasting space on each other's phones, and it keeps our projects separate so we don't get confused.

Confusion is the enemy.
