If these are Office files, I suggest you use Office's own option: see https://answers.microsoft.com/en-us/msoffice/forum/all/my-computer-keeps-making-backups-of-my-microsoft/79411263-08e6-4f7c-b67d-c75933513550 , but check the option rather than unchecking it. Then you can make backups, if desired, using any system you want, not necessarily rdiff-backup. Note that what Office considers an "immediate predecessor" might not be what the client wants. If you take a file made yesterday, change it and save it, then make another change and save it two minutes later, the immediate predecessor is the version that you made two minutes ago, not the version made yesterday. -- Yves Bellefeuille <y...@storm.ca>
