Hard disk space & dropbox

[Weaselboy]

Hi again,
Thanks Weaselboy, it all seems to be working fine - I think the 'migrated' library was created when iPhoto moved over to Photos - everything seems to be saving to the right place anyway.

Now that I have my photos library and my imovie library in the (mirrored) external drive (2x2tb WD MyBook Duo) I was wondering if I can also use the same drive as time machine for all the other bits & bobs I have on the mac?

Do I need to 'partition' the external drive? or can I just set it to be time machine and trust it not to overwrite my photos & movies when it gets full?

(I intend putting my itunes library on there too)

You can use that drive for Time Machine also, but it would be better to make a partition just for Time Machine usage. Time Machine won't overwrite your other data on there, but if on the same partition the Time Machine backup will grow and grow and hog all the sapce not allowing you to add more music for example. A separate partition would allow you to restrict Time Machine space to just that amount.

The problem with this is you will have your data and backup all on one drive. so if that drive dies you wold lose both your backup and the actual data itself. The better way to go would be to have the photos and music etc on one drive, then the backups on a second drive.
