Mac – Backing up a Boot Camp partition

backupbootcampntfstime-machine

I see in the Time Machine options that my Boot Camp partition is excluded. I haven't even tried to remove it from the list of exceptions since I have read that Time Machine will not work with NTFS partitions. Assuming Time Machine won't work with said partition, what is the easiest way to back it up?

Ideally, the solution would work like Time Machine. The problem I anticipate is that I would need a second disk (formatted as NTFS) to hold the Boot Camp backup–or maybe I could also bi-partition my external hard drive and make an NTFS partition to store the Boot Camp backup? That way I would not need a second physical disk plugged in.

What are your thoughts on backing up Boot Camp partitions? Thanks.

You should back up your Windows partition while booted into Windows, using Windows-compatible backup software, and you must backup to an external drive that is NTFS-formatted, whether it is over Ethernet, USB, FireWire or whatever else you can work out. Do not try to use a physical hard drive that has one partition formatted for Mac or Time Machine, and another partition formatted for NTFS. Use a completely separate hard drive.

Don't try to back your BootCamp Windows system up using Mac OS X outside Windows. You might figure out how to back up some files, but you will not be able to create a bootable "bare-metal restore" image, like those people in Windows-land call it.

Windows Vista and Windows 7 have a good built-in Backup utility that can make a full disk image for a full restore, but only to a hard drive that is NTFS-only. They can also do incremental/differential file backups in a separate procedure. And there are many third-party backup software solutions for Windows, such as Acronis.

Trust me, you will not want to try to do this using an Apple Time Capsule or a drive that has a partition that is formatted for Apple Time Machine. A couple of years ago I actually worked out a procedure for doing this using unsupported features on the Time Capsule, and I regretted it, because it interfered tremendously with my Mac Time Machine files when I needed to do a full restore on my Mac partition on my MacBook Pro.
