Here’s a way to use an NTFS drive for Time Machine backups, even though it is used for other purposes too.
Find out the NTFS drive volume’s UUID:
diskutil info /Volumes/DRIVENAME | grep UUID
Put this in fstab: (Replace
ENTED_UUID_HERE with the one you found from the previous command.)
sudo echo "UUID=ENTER_UUID_HERE none ntfs rw,auto,nobrowse" >> /etc/fstab
Eject, plug out and back in. MAKE SURE THE DRIVE WAS SAFELY REMOVED FROM WINDOWS, or it will not mount RW in Mac (See dmesg when plugging in).
Find your RW mounted volume
Now we will create a Mac OS disk image on the NTFS volume.
- Select a large enough size
Mac OS Extended (Journaled)
Single Partition - Apple Partition Map
- When done, mount this image
Now we will tell Time Machine to use this disk. It does not show up in the list of available drives, so we will use a command:
sudo tmutil setdestination /Volumes/MOUNTED-DISK-IMAGE
MOUNTED-DISK-IMAGE with the disk image you created, NOT the NTFS drive)
Now just test backing up and see that it works.
I use this for backing up to my NAS via SMB/NFS
