Re: Problems with OneDrive replication

John, thinking about your scenario, I may not have given a complete picture about how to use FH with OneDrive.
That may be especially significant if you have an unreliable Internet connection.
So the general rule is that not only must you run FH &/or AS on one PC at a time, but also allow OneDrive to synchronise over the Internet in between.
So here is an example.
Say you take your laptop out and about where there is no Internet/WiFi and perform some updates using FH &/or AS.
The laptop is then switched off and taken home. Now those updates only exist on the laptop disk drive in its OneDrive folder.
It is imperative that at home you switch on both laptop and desktop to allow OneDrive to synchronise over the Internet.
Only then is it safe to run FH &/or AS on the desktop PC.
If you don’t synchronise OneDrive first, and run FH &/or AS on the desktop, then the two PC OneDrive folders are out of synch.
Even worse, if that desktop has no Internet connection, you now have three versions of OneDrive data.
One version on the laptop disk, one on the desktop disk, and one in the OneDrive cloud store.
OneDrive will probably not successfully synchronise those three, so your Project data is at risk.
So bear that in mind, and think about where the updated OneDrive data exists before using FH or AS.

Subject: Re: [family-historian] Problems with OneDrive replication
I was not sure exactly how you used the PC copies of the FH Project files, but it is now clear they are redundant leftovers from moving to OneDrive.
I thought you may have been regularly copying files between those PC copies and the OneDrive copies.
It is probably best to delete them to avoid any future confusion, and instead create regular FH Full Project Backups from your live Project on OneDrive.
As you have correctly identified, those OneDrive files are permanently on both your PC disk drives as well as in the OneDrive cloud.
Yes, you can safely delete any out-of-date Snapshot files. Another FH user has experienced similar issues with too many Snapshots.
It looks like all the live files (without the -Chillblast… suffix) have the latest ‘Date modified’ so are presumably your working data set.
There is virtually no risk in deleting all the -Chillblast… or -DESKTOP… suffixed files, but let them go to the Recycle Bin where they can be recovered for a while in case you discover any significant missing data.
The two GEDCOM files may be worth backing up outside OneDrive separately just in case as they hold the most critical data.
It appears that the synchronisation problems arose on more than just 19/01 and 10/02 because there are many more ‘Date modified’ values ranging from 17/11 to 17/02 for the Cache files.
You need to take care that only one application on one PC is accessing those FH files at the same time.
Most customisation settings (such as Queries) are NOT held within Projects, and some are even held in the Windows Registry.
They must be transferred separately and there is advice in the FHUG Knowledge Base on how to do that, and the simplest method employs my Plugin.
Maybe you originally followed the Family Historian V5 & V6 Migration Guide or alternatively the Utility ~ Microsoft OneDrive (SkyDrive) advice.
They both identify my Backup and Restore Family Historian Settings Plugin.
If you need any help with using it then do ask.

Thank you Jane for your input and I will always try to have disciplined housekeeping on FH6 between my desktop and my laptop. I would have said that I never have FH6 open on both computers at once, but perhaps I did break this rule on 19/01 and 10/02 when the two extra copies were created.I will remember in future.
