Inceptions
The archive option isn't available for all lists (for example, you can archive transactions, but you can't archive listings), but whether an item is archived or left in the original list, it is only stored for 90 days through Seller Hub.
From eBay Help:
You can save drafts of your listings to finish later. You'll find your drafts on the Drafts page in My eBay, or on the Manage drafts page in Seller Hub. You can save up to 250 drafts through the quick listing tool on eBay.com and the eBay mobile app, and up to 5,000 through the single and bulk business listing tools in Seller Hub. Drafts expire after 75 days.
