Patent ID: 8572048

Claim:
A non-transitory computer-readable medium storing computer-executable instructions that when executed by a computer control the computer to perform a method, the method comprising: upon determining that a sequence number associated with a first inode description in a disaster recovery (DR) journal entry is out of sequence with a second corresponding inode description in a DR metadump, where the sequence number associated is incremented when an item associated with the inode is accessed by a file system, controlling a DR journal process to provide a file system inconsistency signal and to suspend application of the DR journal entry to the DR metadump as a function of determining that a first access time independent verification code computed from the first inode description does not match a second access time independent verification code computed from the second inode description; and controlling the DR journal process to complete application of the DR journal entry to the DR metadump as a function of determining that the first access time independent verification code is consistent with the second access time independent verification code, where the first access time independent verification code is computed in a file system transaction and is based on fields in a rollback object accessible to the transaction, where the fields in the rollback object are not affected by an access time only update, and where the second access time independent verification code is computed from fields in the second corresponding mode, where the fields in the second corresponding mode are not affected by an access time only update.
