That is, the first time, it backs up everything in the Documents folder (only?). Then on subsequent backups, it will only grab anything that was saved since the previous session. If I'm right so far, then only that first backup has any file that has not been modified and saved again. So if it deletes that first backup before a file is opened and saved again, that file is now gone from TM. If you then discover that this file is corrupt, you're out of luck. Did I get that right? This scenario could happen at any point, not just relative to the very first TM backup.Now, let's say that the default of one back up an hour is in force. Does that mean TM inspects the files somehow, and finding that nothing has been saved since the last backup, it closes without doing a new one?</blockquote>

Verification: How many occurrences of a n-u-m-b-e-r between "d" and "f" in this example...(sdgs6ngklu3gd#f9%)?
