I'm currently backing my entire iMac using Time Machine. I have my photos stored on an external HD which I back up to Time Machine as part of my backups. (Hopefully, I'm doing it right and it's actually backing up the external drive I use for photos too. Can someone tell me how to actually confirm that I'm doing it right and it's backing up on TM?) What I'm looking at doing is maybe also using a cloud service to back up just my photos and videos. Does anybody have any that they can recommend? I know Apple has their own but I read a recent article in a popular Mac magazine and it describe Apple's service as not really a back up service but more of a cloud syncing service so I'm looking for a back up service. Please let me know what you use and what you like and don't like about the service you use.
