I’ve been happily, and ignorantly, doing backups from my mac (10.5.8) to my elements 500 gb drive untill yesterday when it told me it was full partway through a backup. I have about 130 gb used on my computer and the WD drive is full up at about 466. (I assume there’s working space that keeps it from filling all the way up to 500.) I tried running it again asking it only to back up photographs and documents but it didn’t respond at all.
My questions are:
How can I delete some redundant files to make some room?
And, more basically (I really am ignorant about it all): How does the thing work in the first place? Does it save every version of every file? Is there any way to ask it to be more specific? If I haven’t made changes to files since the last backup does it just ignore those and only deal with the ones that were changed?
I imagine that the photographs are the hog (on my computer it’s about 70 gb but I do a fair amount of editing via Lightroom) and I will probably get a separate drive just for them (I already have a separate drive - one that I just manually move what I want to move, not using special WD software - as a second back up for them but will probably get another primary storage or back up unit for them as well.)
Appreciate forthcoming education! Thanks.
