The Sharing preference pane appeared to keep the setting for the partition to act as a Time Machine volume. #How to format a drive for mac time machine mac osIn Disk Utility, I selected the partition and changed it back to Mac OS Extended (Journaled), erased the existing backups, and was back in business. So, while I didn’t receive the error noted at the start of this article again, I was unable to make reliable backups. This seemed to work for a bit with the Macs that previously generated an error connected to APFS. In Mojave or later, encrypting an external volume converts it from HFS+ to APFS (Encrypted). Now, just to add to the confusion: after working through the above difficulties with a new drive intended for Time Machine, and getting all the pieces to work correctly together, I decided to encrypt each of the two Time Machine volumes. Time Machine backups will now proceed as expected. #How to format a drive for mac time machine passwordHowever, in testing, I found I needed to use my user name and password to create the network connection, even though the Time Machine volume wasn’t mounted in the Finder of other family member’s Macs. You should be able to connect as Guest and use it that way because you set up access for Everyone to read and write files to the volume. The networked Time Machine volume appears as a destination. Wait for completion, and the then click Done and the new partition’s volume has mounted.I think doubling the volumes you’re backing up is a good estimate: a drive with 1TB of data could have a 2TB or even larger backup volume to retain a significant long-term set of older versions of files in addition to the current freshest backup state. I recommend estimating the depth of backups you will want for the local machine and the rest of the machines on the network. Name the partition, select Mac OS Extended (Journaled), and choose a size.Disk Utility prompts to ask if you want to add a volume to an APFS container (preferred for managing APFS-formatted partitions) or divided the storage.(If you don’t see the drives, only volumes, choose _View > Show All Devices.) Instead, you seemingly can only backup over the network to an old-school Mac OS Extended (Journaled), known more familiarly as HFS+.īecause Disk Utility can adjust partition sizes non-destructively after they are created, you don’t need to erase your Time Machine drive, but can add an HFS+ partition. While it can mean many things, in the context of Time Machine, it typically means that you are trying to back up to a Time Machine volume on an APFS-formatted partition. You do not have the necessary read, write and append privileges on the selected network backup disk.Īpple doesn’t document this error on its support site, which is a pity. If you format that disk only with APFS partitions, you will try to follow the steps to use it from a network-connected Mac, and receive the following complicated warning: But if you have a desktop machine to which you can easily attached a fixed, high-capacity drive, you can make that drive a Time Machine destination for other Macs on the network. Time Machine can work by backing up to a drive attached directly to a Mac. But Apple omitted a big footnote that should be in its documentation: An APFS-formatted volume can’t be used for networked Time Machine backups. In macOS Big Sur, Time Machine added support for backups onto APFS-formatted volumes (the filesystem that Apple introduced a few releases ago).
