It is important to keep the following in mind when formatting to ExFAT:

• ExFAT is not compatible with Time Machine
• Starting with Big Sur, APFS is now the default for Time Machine
• ExFAT drives must be safely ejected to prevent corruption because ExFAT is not a journaled file system
• When using between macOS and Windows, drives should always be formatted on macOS because not all Windows allocation unit sizes (cluster sizes) are supported by macOS which will prevent the drive from mounting
