You can leverage Batch Apex with Big Objects to copy the data from the tasks and create an archived record in a Big Object.

You can insert the below code in execute method i guess
// Define the record.
PhoneBook__b pb = new PhoneBook__b();
pb.FirstName__c = 'John';
pb.LastName__c = 'Smith';
pb.Address__c = '1 Market St';
pb.PhoneNumber__c = '555-1212';
// A single record will be created in the big object.

but If you are trying to use Database.getQueryLocator method in a Batch class.  it is throwing an 'Internal Salesforce Error' on the queryLocator line.

So you should use Iterator instead (with all its limits).
