Hello! I am hoping to setup a backup solution for my Macbook Pro as well as a couple of external drives connected directly to it via USB, an internal eSATA drive mounted on a Popcorn Hour A400 media player, and an external drive plugged to this media player via USB as well. These last two I access via RJ45 cable from Mac to router to Popcorn Hour. All external drives are NTFS formatted, using Paragon NTFS allows me to read-write all of them with my Macbook. The only automated backup I am performing now is Time Machine which backs up my Macbook HDD to a 128GB pen drive, this works fine. Now I am investigating ways to backup the rest of the drives as well. I was thinking of buying a 4TB WD My Book Studio solely for backup purposes. I know that because it is HFS+ formatted I can use it for Time Machine and get rid of the pen drive solution. Now, as for backing up all the rest, from what I have read, I understand it's possible to backup the two external drives connected to my Macbook but not those accessed over the netowork. In their case, I would have to connect both Macbook and My Book backup drive to those and perform manual backups via USB. Am I thinking any of this correctly or will the fact that all external drives are NTFS formatted be a problem for Time Machine? If so, any software to aid in that?
