How to Manage Large File Uploads on VPS with Chunking and Resume Support

Have you ever attempted to upload a large file to your VPS and became so furious when it failed to upload at 95%? I can relate. Large uploads can be incredibly frustrating, especially if your internet goes funny for a second. That's why I appreciate chunking and resume support; both of which allow larger file size uploads to run faster, injury-free, and with little anxiety.

What Is Chunking?​

Chunking sounds technical, but it is very straightforward. You take one large file and split it up into smaller pieces. Your VPS uploads each piece of the file individually. If one piece fails to upload, you only have to re-upload that one piece as opposed to the whole upload. That is a better way of doing things, don't you think?

Chunking helps you when:

• Your internet drops intermittently
• You upload large files
• Your server limits upload size
• You want quicker and safer uploads

Chunking helps to make the upload feel lighter and more streamlined.

How Resume Support Helps So Much​

Resume support is simply saving your spot in a game. If the upload stops part way through, you can resume where you stopped without losing your time or your data.

Why would you upload a 5GB file again just because your Wi-Fi went down? With resume support, you enjoy:

• Less frustration
• No wasted time
• No repeated uploads
• More control

I can’t tell you how many times resume support has saved me when my internet was going weird.

How Chunking + Resume Support Work Together​

When you use them together, the upload becomes ridiculously strong:

• Chunking will cut up the file
• Resume support will tell you what chunks have finished
• Your VPS will keep track, and rebuild the final file

This combination is so effective that large uploads will be a source of worry no longer.

Tools Available to You​

Most modern systems natively support chunking and resuming. Some popular systems include:

• NGINX + custom scripts
• Node.js with a library such as tus or Uppy
• PHP with dropzone.js
• Python with FastAPI

You don't need to be an expert to implement any of them. Just find a simple guide (there are many available) and you'll be uploading in no time.

Why This Matters Today​

Files are only getting bigger—videos, backups, data sets, you name it. A VPS instance without chunking and resume support feels old and clunky. If you want to upload bigger files more easily and with less stress, this setup will help considerably.
