[QUOTE="IWT, post: 1632596, member: 83420"] Hi karlreed Time Machine (TM), as I understand it, is not meant to be a "long term" store of images or anything else. On first use, it copies everything from your IHD including preferences, photos, music and so on. Then, hourly (and subsequently weekly etc), it only backs up things that have changed since the last BU. In this way, it conserves space. If/when the TM disk gets full, it deliberately deletes the oldest files to make room for the latest changes. If you have precious material - music, movies, photos, documents which you wish to retain more or less indefinitely, then these should be copied to an Ext HD and updated or amended manually. In your case, TM behaved as it is intended to do. You changed your IHD and, if I understand you correctly, you then tried to BU the new IHD. To make space for this, TM had to delete files. Better to have used a new EHD as TM for your new system. TM is great for what it does, but is not bootable. You have CCC which is bootable and can be tasked to sync on a timed basis - say, once a week. In addition, I suggest an additional EHD for those important things on your Mac. Ian [/QUOTE]
