What is a large file size?

This question is subjective and entirely depends on your particular circumstances. Filmmakers, game developers, data analysts – and many other professionals – often deal with large file sizes. Even home users may have large files such as photos, videos, or PDFs that they want to back up.

With this in mind, the truly important question is whether your cloud backup service considers a certain file size too big. As it's this file size limit that will affect whether you can back up your largest files.

So, if you need to back up large file sizes, it is important to check whether your chosen cloud backup service has a file size limit that could cause some of your backups to fail. 

What is a file size limit?

When a cloud backup service states that it has a file size limit, this means that the service does not permit you to back up files over a certain size. As a result, if you have important files that exceed the stated limit, they will not get backed up. 

This can be extremely problematic if the user fails to understand what is going on, because if their device becomes lost, stolen, or broken, they can't recover the files that failed to back up.

Take, for example, a folder on your computer that contains MP4 files of your wedding day. That folder contains a number of videos taken by a professional videographer, and videos sent to you by friends who attended the wedding and the reception. Those videos vary in size; with a couple of them coming in at 1.4 GB and 2 GB. If the cloud backup service you have chosen has a file size limit of 1 GB when you back up the folder Wedding Videos folder – those two videos will get left behind.

It is essential that you're aware of a backup provider's file size limit. And to ensure you pick a backup service that can cater to your particular needs. We have taken file size limits into account when putting together a list of the best cloud backups for large files above. 

Is a cloud backup with a file size limit bad?

This depends entirely on your requirements and the kinds of files you need to back up. That said, there is nothing good about a service that enforces file size limits for backups because you never know when you might have a large file that you need to secure on the cloud.

If you want to save sipped movies, ISO images of CDs or DVDs, or a full disk image of your hard drive, you are going to require a service that either has a very large file size limit or no restrictions.

Some consumers might be happy with a service that has a file size limit, and it is possible that some backup services may cost less because of these restrictions.

However, if you want to back up everything without fear of a file size limit, it is better to stick to the recommended services on this page.
