Abstract:
1. A method of verifying source data backed up from a source storage volume of a source computer to backup media, comprising: reading at least a portion of the source data from the source storage volume; generating a first hash of the source data as the source data is read from the source volume; transmitting the source data with said first hash to a backup server of said backup media; writing by the backup server the source data to said backup media as backup data and writing the first hash to the backup media with the backup data corresponding to the source data from which the first hash was generated; and verifying by the backup server said backup data without the necessity of accessing the source data, comprising: reading said backup data from the backup media; generating a second hash of said backup data as it is read from said backup media; and comparing the first and second hashes to verify the backup data.
