3 Ways to Fix Network Errors When Uploading Files to Amazon S3
Amazon Simple Storage Service, referred to as Amazon S3, is a storage service that uses a web interface to provide storage objects.
Amazon S3 storage objects can store different types and sizes of data, from applications to data archives, backups, cloud storage, disaster recovery, and more.
The service is scalable and users only pay for storage space.
Amazon S3 has four storage categories based on availability, performance rate, and durability. These classes include Amazon S3 Standard, Amazon S3 Standard Infrequent Access, Amazon S3 One Zone-infrequent Access, and Amazon Glacier.
Can Amazon S3 upload a resume on failure?
Amazon S3 can resume failed uploads. Additionally, if your system shuts down during an upload, Amazon S3 can continue uploading after your system restarts without requiring a reboot.
What is the maximum file size we can upload to S3?
Amazon S3 can store files or data of varying sizes between 0 bytes and 5 GB. However, the maximum file size that can be uploaded to S3 at one time is 5 GB.
You can upload files larger than 5 GB using the multipart upload API, which allows you to upload files up to 5 TB to S3.
How to upload large files to S3 from the browser?
- Split the file into different parts using the dd, Linux or split method.
- Start a multipart upload and get the upload ID after starting.
- Upload each section of the file, followed by the upload ID and section number.
- End the upload by submitting an ETag pair, including the upload ID and let number for each part of the file.
You may encounter network errors when uploading files to S3. Some common S3 network errors you may encounter are:
- Unable to connect to the endpoint.
- Missing credentials.
- S3 API returned error.
Here's how to fix these errors once and for all:
What if your S3 upload fails due to a network error?
1. Fix Unable to Connect Endpoint
- First, check to make sure you are using the correct AWS Region and Amazon endpoint.
- Make sure your network can connect to the Amazon endpoint.
- Confirm that your DNS can resolve to the S3 endpoint.
- If you are using an Amazon EC2 instance and setting up the correct AWS Region, check the VPC configuration.
2. Fix missing credentials
If Database Cluster is missingIAM Role Attachment Or no role ARN is provided and only the role name is provided in the parameter group, you may receive a missing credentials error.
The best way to solve this problem is to load the data from S3 command.
3. Fix S3 API return error
The reason for this error may be that there are encrypted files in your S3 bucket or there is encryption in the S3 bucket.
Either way, if ServerSideEncryptionConfigurationExists is true, you can perform the LOAD operation by adding kms* to the IAM role to solve this problem.
