Thank you kindly for the confirmation. Additionally, I am noting that in observing the History tab, that on the Origin PC, BTS does indicate "x" file is updated (.pst in this case), "y" file is added, then removed (.tmp), and "z" file is added (newly created .htm, and newly downloaded .mp3 podcast) Now on the Remote PC{a} and {b}, the History tab does seem to suggest it is aware of these same changes, stating "Origin PC added, removed x, y, z" yet, not all files are showing up in the duplicated directory structure on the Remote PC(s). the .htm files is stated as being added, yet does not show up, the .mp3 does show up. and still waiting on the .pst either as a whole on PC{a} or the updated file on PC{b} ~as an aside, I have the understanding that BTS is technically like a network-based Robocopy, and using the RO Secret assures the Origin PC does not get over-written by Remote PC(s). Since BTS seems to work in some cases, I am sure it is not a Services related issue. I also made it a point to use the following command [attrib -a -h -r *.* /S /D] then followed with [attrib +a *.* /S /D] to refresh (per se) all the attributes of all the files/dir, and nothing changed. (was kinda expecting setting/resetting the Archive bit might have a relation to oddities) Based upon the oddities presented, is this something that suggests that Debug Logging would be beneficial?
