If you are having trouble backing up an exFAT volume with macOS, please contact Backblaze Support for assistance. Please note that exFAT volumes have a history of issues with Mac operating systems.

Drives mounted in this way may be selectable, but are not supported, and we highly recommend against attempting to backup these volumes.Ģ) Directly connected to the computer (USB, Firewire, Thunderbolt, eSATA, etc)ģ) Not a Time Machine backup volume (macOS only)Ĥ) Not mount as a 'removable storage device', as many flash, SD card, CD, DVD, Bluray, and some external SSDs do (Win only) For example, some utilities will allow NTFS drives to be read/write accessible on macOS systems. To be selectable for backup, a given drive must be:ġ) Natively read/write accessible by the operating system. You can add an external hard drive by opening the Backblaze Settings panel on your computer and clicking the "Settings." button.
