Google Drive upload keeps failing on a large file? Here's why

Why does a large upload to Google Drive keep failing?

Each cause leaves a different trace, so start by matching what you see.

What does the 750 GB daily limit do?

On Google Workspace, each user can upload and copy 750 GB to Drive within 24 hours. The interesting line is what happens at the edge. Google's admin help says "Only the first file that breaks the limit completes uploading." So if you upload 600 GB and then a 200 GB file, that file finishes, and every upload after it fails until the limit refreshes, which Google says happens within 24 hours. Read literally, a single file bigger than 750 GB can still finish if it's the first one over.

Personal accounts are vaguer. The consumer help page says only that "Drive users are subject to a daily upload limit" and gives no number. If you're on a personal account and uploads stop after a few hundred gigabytes, this may be why, but Google doesn't publish the figure.

Copies count too. Google says files larger than 750 GB can't be copied in Drive, so you download and upload them again.

Is my storage full?

Check this before anything else, because it's the quickest to rule out. A free Google account has 15 GB, shared between Gmail, Drive and Photos. A 20 GB folder won't fit, however good your connection is. Google's upload help adds a trap. A file you upload takes up space in your Drive even when you upload it to a folder someone else owns.

Drive for desktop has two more storage problems. It needs enough free space on your own disk to sync. And if you sync changes to a file you don't own, the owner's full storage can block you, which Google says you fix by asking them to transfer ownership or clear space.

What happens in the browser?

Google doesn't document it. The Drive API supports resumable uploads, so apps built on it can pick up where they stopped. No help page says whether drive.google.com does that after a closed tab, a reload, a sleeping laptop or a network drop. Until Google says otherwise, treat the tab as fragile. Keep it open, keep the laptop awake and on power, and don't upload hundreds of gigabytes through it overnight.

How do I fix it?

1. Free up or buy storage until the whole upload fits, with room to spare.
2. On Workspace, count today's uploads. If you've passed 750 GB in 24 hours, wait for the refresh. Retrying sooner just fails again.
3. Move big batches to Drive for desktop. When it hits a limit it will automatically retry later. If it doesn't, Google says to wait a day and restart it.
4. Check Lost and Found. When Drive for desktop can't upload a file because of permissions or network errors, it copies the file to a Lost and Found folder on your disk and shows a notification. Move those files back into My Drive to retry. Don't disconnect your account first, because Google says that deletes everything in Lost and Found.
5. Restart Drive for desktop, then the computer. These are Google's own first steps on its troubleshooting page.
6. Give the upload enough time. 500 GB on a 100 Mbps upload takes 11 hours 7 minutes at full speed, nearer 14 at a realistic 80%. The upload time calculator runs your own numbers.

When does a transfer tool fit better?

Drive is good at keeping files. It's less good at handing a one-off delivery to someone. Everything you send counts against your storage until you delete it. A shared link works for "anyone who has the link" without signing in, and link expiry is only offered on eligible work or school accounts. A file many people download can hit a download restriction that Google says typically resets within 24 hours.

Tranzfer is built for the delivery case. You send from the browser, the recipient downloads without an account, and the files are deleted when the link ends. Free holds 20 GB live at once and Studio holds 3 TB. The browser behaviour Google leaves unwritten is the part we test hardest. A dropped connection retries by itself, a sleeping laptop carries on when it wakes, and after a crash or closed tab you pick the same files and only the missing parts upload. How resume works has the details, and resuming an interrupted upload compares what each service says.

When should you stay with Drive?

• The files need to live somewhere after the handoff. Tranzfer links last 14 days at most and we keep nothing after that.
• Your team already works in shared Drive folders and the recipient has access.
• The file is over 3 TB. Drive takes up to 5 TB per file, and 3 TB live at once is our ceiling.
• You want a desktop app that syncs in the background. Tranzfer runs in the browser only.
