Flickr is an image as well as video hosting website that allow users to share and upload photos & videos. Flickr offers a huge storage space of 1 TB to all its users for free. And that is the biggest add on advantage to have a Flickr account. Other services like Google drive, Dropbox etc. offer just a fraction of what Flickr is offering.
So, when we compare Flickr with these cloud storage services, we find that Flickr is a better Photo backup service. The 1TB space is enough to store half a million photos securely in the cloud. If you are not a photographer by profession, this is enough for your life time.
Below is a small comparison between Flick, DropBox and Google Drive
Flickr offers 1TB of storage space
Dropbox offers 2 GB of storage space
Google Drive offers 5 GB of storage space
So, you see the difference? Flickr offers 200 times more space than Dropbox and Google Drive. However, it has just one restriction and that is the size of individual photo. Unfortunately Flickr doesn't allow you to upload a photo which is larger than 200 MB.
It doesn't really affect normal users, however, if you are a professional photographer and usually shoot in RAW than the size restriction might be an issue for you. Otherwise, we do not see any other disadvantage of using Flickr as a Backup service.
Uploading Photos to Flickr:
Flickr offers browser based photo and video uploading, which works fine. But if you are willing to upload 100s and 1000s of photos, then it may stuck in between. To, get rid of this, you can use any other i.e. third party desktop application to upload photos in bulk.
Downloading Flickr Photos:
Flickr doesn't allow you to batch download photos to your desktop or any other location. So, to download flickr photos in bulk, you again have to take help from a Third party desktop tool / application.
