This week I read that Microsoft is going to be offering unlimited storage on OneDrive with a subscription to Office 365 at a price of $10 a month. Since I would like Office 365 and already pay $5 a month for Carbonite backup that I don't like, this seemed like it might offer an interesting option for backing up LightRoom catalogs and RAW files. In anticipation of subscribing to this service, I decided to test Lr's ability to backup to this service.
The catalog backup works well. Create a folder in Onedrive and then point your backup location to C:users\name\onedrive\name_of_folder. When you run your catalog backup it will end up in this folder. Perfect.
For importing, I went into the import dialog boxes and changed my 'Make a second copy to' to another Onedrive folder instead of the second hard drive I have been saving to. This, too, works though it seems to take quite a long time. Initially the folder was empty but in a few minutes my test image appeared. I've not tried this with a half-full 16G memory card. It might bog down pretty badly. I'll have to try it and see. It isn't such a hardship to drag a copy from my backup drive to the Onedrive, but it would be very nice to have it done automatically on import.
