Remove chronosync mac4/7/2023 iCloud limitationsĪpple's iCloud implementation has some startling limitations beyond the fact that there is no plan beyond 2TB. So now that you understand how optimized files are represented in the local file system, and how they're only sort of backed up and not really recoverable, let's turn our attention back to iCloud Drive storage in the cloud. Are you going to go day by day, directory by directory and try to recover what may well be thousands of files, each with a different directory listing on a different day? But when? Are you going to go digging through every day to try to find those files? You might, but it's a pain.Īnd, what if you want to recover an entire directory? Different files were stubs on different days. "But, but, but, didn't iCloud back up those files once, back when they were full files?" Is Apple sweating yet? These 4 companies just turned up the heat at CES They show backup sizes in megabytes (1), but they also show the iCloud download indicator (2). In this image of Time Machine's current view, you can see the four screencasts. Time Machine represents iCloud-optimized files in a couple of ways. In the case of the directory shown above, Time Machine will back up the template files, but those hard-to-make screencasts were not preserved in the backup. Review: Apple Mac Mini (2023): Faster, cheaper, better icloud files aren't really on your local drive, Time Machine has nothing to "grab onto," so it doesn't back them up. In reality, Time Machine only backs up the full files that reside on your Mac. When set up properly, Time Machine runs once an hour and backs up your Mac. But they're only consuming 744 bytes, or roughly 1/85th of the storage they would otherwise be consuming. All four of those screencasts add up to 64.2MB of storage. You can see how there's a lot of local storage savings. They're just tiny little files that represent my screencasts, which are living up in Apple's iCloud data center. MacOS represents those file stubs with a dot at the beginning of the file name and. I'm going to start by showing you how various parts of this overall architecture work, and then I'll put it all together and show you how it can fail. It also took me quite a while to wrap my head around all the not-really-documented nuances. If you fit the profile of someone with more storage in iCloud than on your local Mac, this is mission-critical stuff. How MacOS represents iCloud 'optimized' files on disk The theory is that if you have one Mac, iCloud Drive, and Time Machine backing up to a server or spare external drive, you have a fully valid 3-2-1 backup strategy and your files are safe.Įxcept… not so much. Time Machine is a backup program that runs in the background of your Mac and backs up your drive to either an external drive or a drive located on the network - whether that's another Mac or a centrally located file server like a NAS. If you have a second Mac, you get a third copy, because iCloud syncs down to that Mac.īut there's more. With iCloud Drive and one Mac, you ostensibly get two copies: one is on your local machine and one is in iCloud. We selected a handful of devices that passed our reliability torture tests and offer superior usability and feature sets. If cloud-based servers don't meet all of your storage needs, consider a NAS solution.
