Hello, could somebody shed some light to the question of restoring files backed up by rdiff- backup, please? Given an original file, say file A. It will be backed up with rdiff-backup, and also its increments (assuming that there are many changes to file A). When restoring a given version of that file, a) does rdiff-backup construct the desired version step-wise by applying ALL increments of that file (in chronological order beginning with the original version), OR b) does rdiff-backup start with the original file (file A) and ONLY applies the most recent increment which relates immediately prior or precisely to the timestamp of the desired version to be restored? In my understanding, if a) was true, deleting increments (say older than n weeks) would not always result in the desired version because of probably missing increments. If b) was true, the goal can be achieved. However, as a newbie to rdiff-backup I am not sure at all. As a newbie to rdiff-backup I'd appreciate if the rdiff-backup documentation cover these issues for better understanding the mechanisms of this tool.
