Time Machine backs up to a disk, not to “the cloud,” so Step One is “get a disk to back up to.” For best results, devote an entire disk to the backup task.Time Machine will back up every file on every drive you connect to your Mac, automatically, unless you tell it not to. The odds are very very good that your Mac has Time Machine already installed. Every new Mac has it, and most old ones do too, as it was introduced with System 10.5 (Leopard). Click “Yes” when asked if you want to use this disk for Time Machine backupsTime Machine is Apple’s backup software. Buy an external hard drive (here are some good options)I made a 200GB partion on a 2TB Fat32 HDD in windows, then in mac instructed time machine to use the partition, it tried to format (erase) and now the whole drive is unreadable in mac and.

![]() ![]() Set A Hdd For Time Hine Mac Instructed TimeTime Machine lets you restore older versions of your document– from an hour ago, 6 hours ago, a day ago, 30 days ago, or even last year. You make some changes and then, some time later, you realize that the document was better a while back. Suppose you’re working on a project– maybe a report for school, maybe a book, maybe a page layout document, maybe an art project. In most cases, you’ll use an external hard drive for this. What you need now is a place for your backed up files to be stored. Turns out you’re already halfway there, since the Time Machine software comes pre-installed. Time Machine lets you go back to the time when tall of the images were where they belonged, and then bring them “ back to the future.”I’m going to assume you’re convinced: Time Machine’s the backup system for you. But, today, you see just a few. It’s going to look something like this:Hard drive in my laptop– 1 TB capacity, almost completely full(There are other ways to find out how much storage you’re using– you can use the Disk Utility app, you can use the System Information app, you can Get Info on the hard disk– you can even email me and I’ll help you do it.). Look under the Apple menu for “About this Mac.” Click the “Storage” button. Time Machine is smart and will recognize the disk when it’s there, and the backups will start up again within an hour, without you doing anything else.First thing to do is figure out how big a disk you need to get. If you’re a laptop user and you can’t keep the disk connected when you’re moving the machine around just remember to re-connect the disk again as soon as you can. So, once we set things up, you should keep the disk connected. This is 30 years of experience talking.You’ll need a disk that can connect to your Mac. Get a new disk and dedicate it to backups. Backups are important! Don’t take chances. Now the question boils down to “which disk do I get.” I can help you there too.Note: don’t go cheap here by reusing some old disk you have sitting around. “Don’t Use” means “don’t use,” and you won’t be asked about using that disk for backups again.About that Encrypt Backup Disk checkbox: for some people, checking the box is the right thing to do. Speed factors in three ways: one, when you’re just trying to get that first backup done, two, when you’re restoring items from Time Machine, and three, when you are using the Time Machine backup to transfer stuff to a new Mac.The Time Machine “Do you want to user this disk” dialog boxMore than likely, if you got this far down the page, you’re going to choose “Use as Backup Disk.” If you’re not sure, click “Decide Later” and the Mac will ask you again, next time you connect the disk to the Mac. SSDs have several advantages compared to old-style spinning hard drives:You might wonder why “faster” is important. Call them if you’re not sure which disk to buy!If you’re willing to spend a little more, get a solid state drive (SSD). Here’s a link to the external hard drive section at MacSales.com. If you have a really new MacBook or MacBook Pro (the kind with USB-C ports and nothing else), you need something with a USB-C connector, or else you need one of Apple’s USB-C to USB adapters.You can find external USB hard drives at Apple stores, at Best Buy, at Staples, etc. 7z converter for macIt’s going from your Mac, through a cable, to a backup disk on your desk. Remember, your information isn’t flying across the internet, where it’s easy to steal. Being locked out of your backup disk is a very bad thing, so I don’t advise encrypting the backup disk. In my experience, encrypting the backup leads to extra stress and confusion when trying to use the Time Machine backup to restore files, because it’s one of those passwords that isn’t required very often, so people forget that there even is one. You won’t be able to access the files on that backup disk without the password. Sounds like a good idea, but there’s a password involved, and if you forget the password, you’re sunk. At least it does by default. It had better be sometime within the last hour, because Time Machine is supposed to back up every hour.One more thing: as mentioned above, Time Machine backs up every disk connected to your Mac. If Time Machine is not busy it will show you the time of the most recent backup. The Mac had a snapshot of that day, but eventually the system has to create space, so it throws out the old snapshots as needed. But, if you had a bunch of stuff in the trash the first day you used Time Machine, and then some time after the first backup you emptied the trash, you wouldn’t be able to go to to when the stuff was in the trash anymore. That’s no big deal– you’re still backed up. At that point, you either get a new disk (and you know how to set it up to be the new backup disk), or you let Time Machine delete older “snapshots” of your Mac. The drive might have failed, or it might not be connected (laptop owners, I’m talking to you), or maybe the checkbox in the Time Machine preferences, the one that says “Back Up Automatically” is unchecked.Also, this doesn’t qualify as something “going wrong” but it’s still a thing: some day, your backup disk is going to be full. Ooopsy! You haven’t been backing up. Most things DON’T change (fonts, system files, applications, many documents, most music and images) so these hourly backups don’t take long. But subsequent backups– which will occur automatically on an hourly basis (this is why you keep the disk connected)– only need to backup up what’s changed since the previous backup.
