data loss

The inability to take action to recover data. Data loss can be the result of transactions being copied that were lost when a failure occurred, non-committed transactions that were rolled back as pat of a recovery process, data in the process of being replicated that never made it to the replica because of a failure, transactions that were committed after the last tape backup when a failure occurred that required a reload from the last tape backup. transaction processing monitors (TPM), message queuing software, and synchronous data replication are measures that can protect against data loss.
