I used Dropbox for years to keep my files safe and to be able to recover them in case anything happened. In the end, it turned out that Dropbox was the worst thing that could have happened. In recent years, they released this online-only feature which makes sure only your most recently used files remain in your hard drive. The other files become online-only which means you see a placeholder on your device and when you try to open it the file gets downloaded first and only then opens. The idea in itself is genius and seemed to work pretty well at first. Eventually, I found out that when copying online-only files from one place to another those files would be copied as 0-byte files without any reference to the original file. I also found out that when uploading online-only files to a website on my browser they get uploaded as 0 bytes instead of the original. This also means that if you move a folder that contains some online-only files those files will be lost because they have no reference to the original and will be uploaded to Dropbox as 0-byte files. At some point, the situation I described above happened to me. I moved a folder from one place to another and a few minutes later decided to revert by moving it back. When I moved the folder my online-only files were moved and upload as 0-byte files and when I reverted my action it didn't matter anymore because they were already just a bunch of 0-byte files on my device and also on the cloud. I only found out a few months later that this happened. Now Dropbox claims that this wasn't their fault. They told me that they simply listen to path changes and upload whatever changes on the Dropbox folder on my device. It isn't their fault that I don't understand how online-only files work and that I didn't make sure they were all downloaded locally first. They refuse to take any responsibility while I lost some of the most important files I ever had. It is extremely upsetting that I have been paying them to keep my files safe and now they simply refuse to recognize that their feature might not be as intuitive as they thought. Even worse is that they claim to no longer have any backups of those files that were lost. Therefore, I have no way of recovering them. Based on this experience I seriously recommend that you stay away from this company if you want to keep your files safe.
