Hi thanks a lot for your answers I have retried with a new test scenario its clear now and deleting an incremental is really dangerous. But I think that a function that enable the administrator to "join" 2 jobs would be cool. Imagine that one day lots of data manipulation are done on the machine that I want to backup, so there is a great difference between 2 incremental. The jobs are done, and deleting one job is dangerous for the jobs that follows In this case, that would be great to mix 2 jobs. Its quite complicated to explain I know. Take a look at this little scenario, a classical Full with his incremental jobs : the client is typically a big file server
1 - The full 2 - an incremental 3 - someone make a mistake while he was exploring the file server he made lots of copy of files in the server (for example : a bad drag and drop). 4 - a nightly scheduled incremental 5 - the administrator see that the last incremental got a lot of new files and that job bytes got a huge value. 5 - the user see his error and deletes the duplicates 6 - a new incremental is ran 7 - after checking everything, I want to reduce the size of my backups by "fusioning" the two last incrementals. The idea is to add new files of step 4 to step 6 but without the files deleted at step 6 In a mathematical view, it can be seen like that : Inc6.1 = Inc4 - (Files of Inc4 deleted at Inc6.0) + (new files of inc6.0) + (crush files modified after Inc4 with their version of inc6.0) I hope that it can be understood more easily than the previous post !
