Using Same Backup Drive For Both Windows And Mac

[Oka]

Now I got to back up the MacBook to a new external USB drive, my next quetions would be partitioning.
The previous external USB Drive I used had two partitions, Windows and Mac accessible, but on each partition on the same external drive. I had not issue for the at lease six times I have accessed this drive. Now I got a more portable drive and just have the Mac access to it.

Has anyone had issues with using same drive for Windows (NTFS or FATS) and Mac (Mac OS Extended Journaled)? Any complication s to look out for, or, is it not even advicable?

I need to do it again since 1T drive is really too lard for my Mac backup. Would like to backup twi iPhones
and a MacBook Pro to the Mac partition. Then backup just the two iPhones to my PC and back that up to the Windows partition on the same external USB drive.

Thanks.

FWIW, I've used several disks with multiple different FS partitions. I think I started by formatting the drive and creating two partitions in Disk Utility via OS X (in the standard HFS+). I then left one partition with HFS+ (Mac), and the other I formatted to ExFAT (Mac+Windows). Then, in Windows, I formatted the ExFAT partition to NTFS. I did this because I hate ExFAT (even though it works on both Mac and Windows), FAT32 file size limitations made FAT32 impractical for me, and I've never been totally thrilled with 3rd party or OS X's built in NTFS write support. However, for quite a while I've just been using different externals for each given my 1tb 2.5 inch drives are only like $55 for the premium performance model.

. . . . and you haven not had any hicup just by using same drive?

My internal iMac (spinning) hard drive has one MacOS Extended and one NTFS partition on it. I use the MacOS Extended partition purely for Time Machine (no OS), and NTFS for Windows 8.1.

Had this setup for nearly 5 years without a single hiccup. Don't see why it would be any different with an external drive.

There shouldn't be any issues. Except of course the fact that all your eggs are in the same basket, so you really should be used my nyktiple redundabt backups.

No issues at all, but I eventually just went to a single drive for each given I was using them with different computers and the low cost of HDDs.
