Actually I have completely given up on Personal Vault.
When I was doing a backup of my OneDrive to an external drive, I forgot to exclude Personal Vault (which on my machine is empty) and it hung the backup process (which was just a Copy via File Explorer).
Personal Vault is a half-baked solution to nothing, and I hope they make it an option, as I don't want it. What purpose does it serve?
- If I have no malware on my PC, Personal Vault serves no useful function.
- If I DO have malware on my PC, it will get to see in Personal Vault if it just waits till I open it.
So please, Microsoft, what on earth is the point?
I ran an experiment with an app that kept a file open, let the vault time out, and when I tried to save changes in the app, ie write to the open file, the app crashed, as the file was either no longer open or at least could not be written.
I lost all my changes. This can happen so easily, at that point I completely gave up on Personal Vault as being too dangerous to use. My data is too precious to lose updates like this.
