A backup method for a computer system that affords fast verification of source data written to backup media includes reading a portion of the source data from a source storage volume and generating a hash of the source data. The source data is written to the backup media as backup data, and the hash generated from the source data is written to the backup media and associated with the backup data corresponding to the source data from which the hash was generated. Verification of the backup data can be subsequently performed by reading the backup data from the backup media, generating a hash from the backup data read, and comparing that hash with the hash originally stored on the backup media. This enables the backup data to be verified as corresponding to the original source data without the necessity of rereading the source data from the source volume, and enables faster, more accurate off line verification subsequent to the backup process.
A method of backing up source data from a source storage volume of a computer system to backup media, comprising:
A method of backing up source data from a source storage volume of a source computer to backup media, the source data being stored on said backup media as backup data with an associated hash of said source data, comprising:
Computer readable media comprising instructions executed by a computer system to perform a backup method to back up source data from a source volume to backup media, the method comprising:
