Consistency check

A consistency check is a strategy used to harmonize data found on a computer system. The idea behind the check is to ensure that all data is synchronized between primary and secondary data groups, also known as protection groups and replicas. A consistency check may be configured to take place at designated times or implemented manually if there is suspicion of some type of conflict in data since the most recently completed check.
Resolving internal conflicts is the main focus of a consistency check. Many systems include what is known as a data protection manager that reviews data in blocks, making sure the protection group and the replica are in harmony. In the event updates in data have occurred with the protection group but not the replica, the manager adds the updates to the secondary data group, resolving the conflict.
The process of managing this type of check varies somewhat from one system to another. Usually a system administrator can establish a recurring schedule for running the check at least once every twenty-four hours. For example, the check may be set to occur just before midnight each day. It is also possible to set the recurring checks on specific days of the calendar month, or to occur on a weekly or biweekly basis. Establishing a schedule of standing or recurring checks does not limit the ability of the administrator to conduct random checks when and as desired.


If a consistency check is so important for a computer system to run,
imagine how important is for a human system?

Πολυαγαπημένη μας Νεράιδα! Άρχισες πάλι να γράφεις! Έπιασες το μαγικό σου ραβδάκι και εμπλούτισες το ημερολόγιό σου! Από τα τρέχοντα άρθρα σου κρατάω το εξής. Το παν για να λύσουμε ένα πρόβλημα, ή να θέσουμε ένα ζήτημα, είναι να παρατηρήσουμε και να συνειδητοποιήσουμε. Αν τα δεδομένα φεύγουν απαρατήρητα και δεν συνειδητοποιούμε τη λεπτοδουλειά της συνειδητοποίησης πριν τα προγράμματα και τους στόχους, πάμε στα βράχια. Καλά να περνάς και με πολύ όμορφα συναισθήματα στην ψυχούλα σου!!
