Restored yesterday's 1PW backup - the backup is missing nearly 2,900 passwords

This Mac is set up to run a 1Password WLAN server which includes syncing of this vault to iOS devices. Also sync with primary vault on iCloud

@Ben, I just sent that diagnostic info to support. I should have mentioned in the email that I am backing up into a Sync.com cloud.

@Ben OK here's what just happened. When I restored, it apparently lost track of my registration. I just got a nagware message to "Upgrade to 1Password 7" for just $2.99/month or somesuch. It honestly looked like a promo, not a legit login prompt or workflow process. I dismissed it a couple of times, but just now for grins, I clicked the tiny link at bottom of this dialog to "activate an existing membership" It then prompted me to sign in, which I did, and all passwords restored.
So - semi solved for now.
And - that seems like a slightly non-obvious broken/misleading UI problem. >_<
That said, earlier you commented that "_Syncing the same vault with multiple services is not a supported configuration_" Lets talk about your recommended best practices around this. Seems strange to offer such config option to the user in the GUI without any warnings or caveats there to state this.

Lets talk about my use case: I consult to public and private agencies, both US Domestic and Foreign. I often have secure access to their webservers and other cloud-based storage for collaboration. Besides a security hardened MacBookPro, they require that my 1PW backups reside on something other than DropBox, iCloud or Google Drive. I use Sync.com - they have a Global data privacy compliance policy adequate for these requirements and more robust than the aforementioned cloud services. This is where my restore points are for 1PW. Please let me know if I should consider a different way to provide sync for my macOS 7 iOS devices. :)

I apologize if this is a duplicate post. The forum interface is giving me serious glitches when I tried to edit this post for accuracy.
