[QUOTE="MacInWin, post: 1833598, member: 396914"] Given what Charlie said, that TM does not delete snapshots after making a backup, does anybody know HOW they get deleted by the system automatically? I've never run those terminal commands, yet I only have two snapshots, one at each time I have TM automated to be turned on, make a backup, and then turn off again. I never see more than the two snapshots, rolling through the day. So *something* is deleting them, and it's not me. I thought snapshots were temporary backup files created by TM when the backup disk is not attached and that once the backup gets made, the snapshots are not longer needed and are therefore deleted. But this article: [url=https://support.apple.com/en-us/HT204015]About Time Machine local snapshots - Apple Support[/url] seems to say that the snapshots are deleted after 24 hours, backed up or not. That activity would be consistent with what I see, that is, two snapshots in the previous 24 hours. So is that it? Just a clock? That would mean that if you don't have the TM drive attached while traveling, for example, for a week, you have NO backups of the six days of the start of the week when you return home to the TM drive. Seems to me that would be something pretty important to know in a business environment. Just sayin'. [/QUOTE]
