Can someone provide me with a list of cloud database options for data archival and retrieval purposes?

I have an issue with "Exceeded Data Storage" limit in one of my Salesforce Orgs.

Possible Solutions:

Buy additional data storage space from Salesforce.
Delete the unwanted data and archive the remaining data on a periodic basis on business needs in an External Database.
Provision to access the archived data from Salesforce whenever I want to. This retrieval of data is just display of data in Salesforce

My questions:

There has to be code written in Salesforce for pushing data from Salesforce to External Database during archival, but do we have to write code at the database level as well to store and retrieve data?
If the answer is "No" can you suggest some affordable cloud database options where this operation can be done seamlessly?

Possible Solutions:

Buy additional data storage space from Salesforce.
Delete the unwanted data and archive the remaining data of specific time period based on business needs. This arcihval done on an external system/database should enable me to access the archived data through Salesforce whenver I want to

My questions:

What are the best ways to do this data archival process which will involve two way data integration, data flow from Salesforce to an external database and access of the same data through Salesforce (data retreival)
Which database/external system would fit for this functionality?
Had there been any implementation done by anyone on this?

I would need answers specific to Salesforce implementation testing
