In wwDC’s 2020 opening speech, Apple didn’t reveal much information about files apps in iOS/iPad OS 14 systems, one of the reasons may be that the scale of the adjustment was not large. APFS encrypted disks will soon be supported in file management for iPhones and iPads,media 9to5Mac reported.
In the iOS/iPadOS 14 system update, users can access the encrypted disk through the File application. The feature is now available in the first beta version of iOS/iPad OS 14, and has been successfully tested on iPad.
Apple has made the process simple and intuitive, so using an encrypted drive on iOS isn’t complicated. All you need to do is plug the disk into your iPhone or iPad via a USB-C or Lightning port and open the Files app.
The encrypted disk appears on the redesigned sidebar. Once you have selected it, you will be asked to enter the disk password you set earlier. Just enter your password and click Unlock to access all the files on the disk.
The disadvantage is that iOS 14 and iPad OS 14 only recognize disks encrypted in APFS format. If you are a Mac user, you can use the macOS pre-installed disk utility to properly encrypt the disk.
Related to this, macOS Big Sur can now back up Time Machine to a PFS disk. In macOS Catalina and previous versions of the operating system, Time Machine is only compatible with HFS plus disks, as Apple explained in a support article.
Important: You can back up the contents of an HFS plus or APFS format disk to an HFS-plus disk, but the time machine cannot back up to a disk in the APFS format. If a backup disk in APFS format is selected, the time machine can reformat it to HFS plus.
If the disk uses the Master Boot Record (MBR) partition type, some partitions may not be available in the time machine.
If the backup disk is on a network, the network server can use the Server Information Block (SMB) file share. When setting up the time machine, your Mac must be connected to the SMB server. When a network disk is selected in time machine preferences, the time machine automatically connects to the disk when data needs to be backed up or recovered.
