1. A computer-implemented method for data sharding and topology alterations for disaster recovery preparation, the method comprising:
estimating time needed to copy a data store of a data center that is assumed offline;
determining whether the time needed is greater than a recovery time objective (RTO);
in response to determining that the time needed is greater than the RTO, creating a data shard for the data store; and
prior to the data center being offline, altering a current topology of the data store in a network connecting multiple data stores, by copying the data shard to a destination data center that does not contain the data store in the current topology, wherein, with an altered topology, the RTO is met in an event of the data center being offline.
