Abstract

A method for verifying data copies generated by a data protection system is provided. In accordance with the method, intents for selecting a data copy to be verified are determined. The intents may specify a time period after which data is to be verified and an interval for which the verification is to be repeated. Additionally, utilizing the intents, a data copy matching those intents is identified and verified. A data copy may be verified by comparing a checksum of the data copy with a known checksum value. If the data copy fails to be verified, a copy of the data copy is generated.
