Archive data comprises of more seasoned information that is as yet essential to the organization and might be required for future reference, and in addition information that must be held for regulatory compliance. Data archives are indexed and have search capacities so that the records and parts of documents can be effectively found and recovered. Often people get confused with data archive and data backup. Data backup is a mechanism that relates to the recovery of data when the data gets destroyed or corrupted. Whereas, data archives are used to protect the older information that is not required for daily operations but needed occasionally. Hence data archiving reduces the primary storage and related costs.
Indexing refers to the organization of information as per a particular pattern or plan. We know that data is stored in the form of records. Each record has a key field, which causes it to be perceived extraordinarily. Indexing is a data structure technique to effectively recover records from the database documents in view of a few characteristics on which the indexing has been finished. Hence indexing can be extensively alluded to as an indicator or measure of something.
