However let me put some thoughts forward for your consideration:
1 Using on line storage entails you having confidence in the storage facility, that the storage will be secure and access controlled so that unauthorised folks are kept away from it (you are essentially passing your back up material over to someone....) you need to have confidence that they will look after it properly and take steps to back it up themseves, otherwise if their storage fails, your data could go with it!
2 On line back up with reputable organisations can be very useful, especially if backing up files or folders with your photos, documents, music, videos etc . However it can be limited by:
3 the amount of storage space available
4 the speed of your Internet connection.
5 You may have an ultra fast fibre optic broadband connection with speeds around 100Mbps (you would be very fortunate but these sort of speeds are possible) and if so the speed is unlikely to be a great barrier.....but if you are like a lot of folks running on a good old copper wire at a download speed of say 4 or 5Mbps on a standard ADSL broadband connection then it could prove very difficult for the large file sizes needed to achieve the most common size of disc image that we are usually dealing with. With ADSL it means what it says..the speed is asymmetric..the upload speed is often lower by a considerable factor than the download speed available somethimes it is only 10% of the download speed......
4 I will leave you to do the maths, particulary as only you know the upload and download speed of your connection...but if for example I was to store a disc image of 50GB online and upload it via my copper wire ADSL broadband connection .......the time taken would be measured in months...Yes, that's right, months! (and that's assuming that the computer would be running 24 hours a day 7 days a week and doing nothing much else, other than uploading the disc image ...... however when it comes to retrieving the image file the time would be shorter, but still for me totally hopeless. For this reason the answer for me on my connection speed has to be say, an external hard drive.
5 To sum up online storage can be suitable especially for smaller size back ups, or with ultra fast connections ( but do calculate the times needed before using or buying online storage)
Here's a link to a site with some details that might be helpful
Hope this helps
