Installed Windows (clean install), then FDISR and made a couple of snapshots - one for testing software, another a copy of my Primary Snashot, etc. I then installed programs, restored backups, etc. Now, when I go to copy my Primary Snapshot, I get 4 errors. The error log simply says 'Copied x files, etc, and then 'Errors 4', and that's it - no info about the errors. The strange thing is that if I make a copy of my Primary Snapshot as an Archive to another drive, I get no errors. Why could this be? I've never had errors copying snapshots before. In fact, I've never had any FDISR problems before. Also, copying another snapshot is fine, it's only my Primary Snapshot that causes errors. I know that I have an archive as backup, but I was wondering if anyone else had experienced similar with their Primary Snapshot only? Very confusing.
