Hi, All this is about 10.9.5, and Time Machine backups on LAN. Recently some items were removed from TM backup, the star-wars display, not the TM exclusion rules. These were some apps of big size which are updated frequently and generate huge amount of backup data: Safari, Numbers, Pages, Keynote, some 3rd party apps as well. It means as for needs of this Mac it is sufficient enough to have just one backup of every such app corresponding to current status. Therefore subsequently to the removal described above a TM backup process was started. Based on the number of removed backup items and these names the estimated size of next backup is somewhere between 1 and 2GB. The problem is that the backup following the backup items removal operation include 30 to 50MB of data (several attempts were made). It means the TM does not include the apps in the backup which were removed. For all affected apps there is no exclusion rule! What is the possible reason of this behaviour? How to fix?
