Systems and methods for preventing unintended data loss during data restoration
A computer-implemented method for preventing unintended data loss during data restoration. The method may include (1) detecting an attempt by a user to restore data to a storage system, (2) analyzing an effect of restoring the data to the storage system on collateral data that was created subsequent to a point in time to which the user is attempting to restore the data, (3) determining, based on the analysis, that restoring the data to the storage system will destroy the collateral data, and (4) enabling, in response to the determination, the user to perform a remedial action on the collateral data before the data is restored in order to prevent unintentional data loss. Various other methods, systems, and computer-readable media are also disclosed.
