Hello and Happy New Year :)

I have 24.000 images uploaded yo my website and shared this images to my Forums - Sites! Before this i stored my images to Flickr and they block my account and lost everything from my Forums - Sites and now replace every image 1 by 1 with new links from my Image Host! My VPS is to Contabo!

I have 1 very important question:

Is there any reason to can happen the same think ? I mean to lost all my images and see this images broken to my forums ? My Image Host is for personal usage! I take every day backup!
