Glacier Deep Archive Storage - Content Backup process & Pricing

Hi,

My requirement is :

• Upload 50 TB of Data to Glacier Deep Archive Storage
• the most cost effective method
• Region : Asia Pacific (Mumbai)

The data to be uploaded had following specification :

1. File Type : fbx/exr/ word/ excel/pnf/pdf/etc
2. No of objects : No idea about this and not possible to calculate as the data is of huge size
3. File size : 36kb to 200 gb

I did a trial :

1. Uploaded two files and deleted one
2. The bill that it shows isn't making sense with alot of breakdowns. Not able to understand

Require help with :

1. The best process to upload my 50 TB data to Deep Archive storage so that monthly cost remains minimal
2. Monthly Pricing and breakdown : What will the monthly bill look like for the data specified above and the amount? The pricing calculator is confusing for someone not familiar with AWS.
3. Understanding of my bill -

I am a non technical person, so would need help with the steps for uploading the content to storage.

Also how to attach screenshots.

Hoping for a solution here, Shabnam
