    Does anyone know if you can use Time Machine to back up to a SD memory card? I am interested in installing a 32GB SSD in the ExpressCard slot of a Mac Book Pro. I have looked around and haven't heard of anyone trying this.

    I don't see why not but the drive you are backing up would have to be less than 32GB. That seems unlikely.

    Not necessarily; you can exclude files and folders from being backed up with Time Machine.

    I do this myself; My VMWare virtual machines directory isn't backed up with Time Machine (since it'd essentially have to copy the entire disk image each time), nor are all the system files and folders (I have my OS X CD for those)-- just my user data. A 'full backup' of everything else worked out to something like 10-12GB.

    It would work, just mount the drive in OS X and launch Time Machine. Select the 32GB SSD.

    Oh, another note; You'll have to have the drive formatted HFS+ to get Time Machine to use it. Most SD cards come formatted as FAT32-- use Disk Utility to reformat it.

    Thank you for the info

    I have a sales person that seems to always be losing documents and I was trying to find a way to get them a portable backup. Sounds like this will work just fine for the document folder and desktop.

    Thanks again...

    Sounds like an expensive way to back things up!

    (just a thought..) but wouldn't it be easier (if possible) to just partition the hard drive and back up to another partition on the same disk?

    Obviously if the drive dies you lose everything, but just for files and documents that he might lose it should do the job.

    You can't backup onto the same disk using Time Machine. And as you said, if the drive dies, you loose everything.

    I was also thinking of buying a Expresscard adaptor with 32GB SD card for making backups on the move.

    Does anyone know if you can bootup from this combination? If so hopefully it will handy to increase battery life without lugging a spare or adapter around?

    I use SuperDuper to clone my internal (weekly), but should be possible to do this daily to SD card.

    I don't know the speeds for the Expresscard adaptor with 32GB SD card - If you don't use the card in other devices, maybe a simpler and faster way would be to buy a Transcend 32 GB ExpressCard/34 Solid State Disk: About £60 - same price as a Expresscard adaptor with separate 32GB SD card.

    That's my problem. I have to use a memory card to move data to a Windows machine, but would like it to be backed up when it's connected to my Mac.

    Sure it works. My belt-and-braces approach to backups has a wee 64GB USB flash drive permanently plugged into my McBook in case I need to rollback or recover if away from my network. At the moment -the only extras I have installed are Office and a few bits and bobs - a complete new backup is about 29GB. It's a slow process, but I've restored from the drive a couple of times after brief scuffles with El Capitan with perfect success.

    I love TimeMachine, anyone who's had failed recoveries using Windows backup software such as True Image has to appreciate it.
