A consistency check harmonizes data on a computer system and ensures that primary and secondary datasets are in sync. It resolves conflicts and can be scheduled to run regularly or manually. The process compares every block of data and may slow down the system, so it is best to run it during off-peak times.
A consistency check is a strategy used to harmonize data found on a computer system. The idea behind auditing is to ensure that all data is in sync between primary and secondary datasets, also known as protection and replica groups. A consistency check can be configured to run at set times or implemented manually if some type of data conflict is suspected since the last completed check.
Resolving internal conflicts is the main goal of a consistency check. Many systems include what is known as a data protection manager who examines the data in chunks, making sure that the protection group and replication are in harmony. In case data updates have occurred with the protection group but not with the replica, the manager adds the updates to the secondary data group, resolving the conflict.
The process of managing this type of audit varies slightly from system to system. Typically, a system administrator can establish a recurring schedule for the audit to run at least once every twenty-four hours. For example, the check can be set to run just before midnight every day. It is also possible to set recurring checks on certain days of the calendar month, or to have a weekly or bi-weekly frequency. Establishing a permanent or recurring audit schedule does not limit the administrator’s ability to conduct random audits when and as desired.
The actual process of conducting a consistency check can take some time. This is because the check is not simply looking for exceptions, but actively compares every single block of data between the two groups. In this way it is possible to identify any damage that may have occurred in one group or the other and offers the possibility of repairing the damage. Some systems will report discrepancies, allowing a system administrator to review conflicting data before the chances actually arise.
Attempting to restart a system while a check is in progress is generally not recommended. This process can corrupt your data or cause other adverse effects, depending on how your system is configured. If an emergency consistency check is initiated, it is usually a good idea for end users to refrain from attempting to use the system for any reason until the check is complete.
In addition to taking time to complete, this check can also slow down other activities on the system. This means that end users may notice a change in the speed with which they are able to access different databases or use any of the other programs plugged into the system. For this reason, a computer consistency check is often set to run at off-peak times, such as after the workday is complete or at night when home computer users are asleep.
