Abstract
Example embodiments of the present invention relate to a method, a system, and a computer program product for verifying the integrity of replicated virtual machine data. The method includes reading data from a production volume at a production site. A representation of the data may be stored at a replica site with the integrity of the data stored in the replica volume being verified according to the representation of the data.
Claims10
A system, comprising:
- one or more processors;
- and
- a non-transitory computer-readable storage medium having computer program code encoded thereon that is executable by the one or more processors to perform operations comprising:
- receiving a hash of production data that resides at a production volume of a production site;
- storing the hash to a replica site journal of a replica site;
- receiving an encrypted copy of the production data;
- storing the encrypted copy of the production data in a replica volume at the replica site;
- and
- verifying integrity of the encrypted data stored in the replica volume by performing operations, at the replica site, comprising:
- reading out, and decrypting, the encrypted copy of the production data;
- hashing the decrypted production data;
- comparing the hash of the decrypted production data with the hash stored in the replica site journal, and either:
- marking the decrypted production data as compromised when the hash of the decrypted production data does not match the hash stored in the replica site journal;
- or,
- providing access to the decrypted production data at the replica site when the hash of the decrypted production data matches the hash stored in the replica site journal.
