But for earlier MacOS versions like Catalina, Mojave. The best drive format for a Time Machine backup is APFS. When your MacBook Pro, MacBook Air or iMac is running MacOS Big Sur (version 11.0).Double check that you do indeed have a good backup. They are the same thing.Now browse to folder containing your STOP/DJVU encrypted or the reference file. You’ll see HFS+ listed in your Mac’s operating system as Mac OS Extended (Journaled).
![]() ![]() Encrypt Your Bavkup Drive Mac Is RunningThe only option the backup program has is to back up sector-by-sector.Unfortunately, things still aren’t quite so simple.Curious how disks get encrypted in the first place? How Do I Encrypt a Disk? will tell you. Outside Windows: if you instead boot from a backup program’s recovery disk to perform a backup (an option in many backup programs), then you’ll not have mounted your Windows system disk, and its contents will not be accessible to the backup program. It should be able to perform a content-aware backup just as if the system drive were not encrypted. The system drive is completely accessible, not only to Windows but to all the programs you run, including your backup program. Inside Windows: if you install a backup program in Windows and run it from within Windows, it works because you’ve mounted the system drive and supplied the password. The only thing it can back up is each physical sector on that disk because it might contain data.If your system drive is encrypted, there are two scenarios for backing up. That means either of two things: It simply does what it does, which is to back up what it sees: the hard disk’s unencrypted original contents.If it’s important to you that such a backup be encrypted, you need to take additional steps. The fact the disk is mounted and accessible means the backup program neither knows nor cares that encryption was used at all. I say “by definition” because the very reason a backup program might resort to a sector-by-sector backup is that it can’t understand the encrypted data.Backups taken from within Windows while the disk is mounted and accessible are typically not encrypted. Is the backup encrypted?A sector-by-sector backup is, by definition, encrypted using whatever whole-disk encryption technology is being used. Not only does that take significantly more time, but it also can’t be automated and, quite honestly, doesn’t make much sense to me.I think it’s important that you be able to back up from within Windows. It should just work as if the disk were not encrypted at all. In other words, if you install and run it within Windows with your encrypted disk mounted and accessible and it complains, that’s not the program I’d use. Back up using a program that uses “content-aware” backups. Encrypt the resulting backup file(s) yourself, using some encryption tool for example, you might create a password-protected zip file containing the backup after it’s completed, or place the backup in a VeraCrypt-encrypted volume.Whole-disk encryption is a fine thing, 1 and I use BitLocker on my Windows laptop and Apple’s equivalent on my Macs. It could also mean that you’ve structured your backups to be secure somehow — perhaps backing up over a network at home to a device you trust is secure enough for your needs.Related Questions Can you back up encrypted files?Yes, encrypted files can be backed up. That could mean encrypting it, as described above. Save the backup securely somehow. You can also back up a BitLocker drive at the encrypted sector level, but this will require you to save the encryption keys separately to restore and decrypt the drive or its contents. It’s most easily done using traditional backup software to back up the unencrypted contents of the drive, and then securing that back up some other way — perhaps through the backup program itself, separately encrypting the backup, or storing the backup securely. Can you back up a BitLocker drive?Yes, you can back up a BitLocker drive. Should backups be encrypted?Backups should be encrypted when they contain sensitive information and are stored in a less than totally secure way. Finally, many backup programs include the ability to password-protect a backup disk, which encrypts the backup contents. You can also encrypt the backup files themselves individually, using tools like VeraCrypt, Zip, or others. You can use whole-drive encryption, meaning the drive’s contents will be accessible in unencrypted form whenever the drive is mounted. Fusion 360 for mac free downloadIf it’s a drive encrypted elsewhere, when you attach it to Windows you’ll either be asked to provide the backup encryption key, or you may need to right-click on the drive in Windows File Explorer or Disk Manager to do so. If it’s another drive that Windows already knows about, that too will be automatically mounted. If it’s your system drive, that will have happened when you signed in to Windows. How do I copy files from a Bitlocker-encrypted drive?To copy files from a drive encrypted using Bitlocker, first mount the drive in Windows. It’s also common to make sure that unencrypted backups are stored in some kind of secure way, such as offline or in an inaccessible location. This will create backups that require that password should they ever need to be used. ![]() If a thief gets hold of one of my laptops, it is possible that he can delete my data, which would also delete it from the online copy.
