Data redundancy is a condition created within adatabase or data storage technology in which the same pieceof data is held in two separate places. This can mean two differentfields within a single database, or two different spots in multiplesoftware environments or platforms.

Thereof, what is redundant capacity?
Available Redundant Capacity is the term used inpower planning that customers may not know, but they do ask for itdaily. What they ask is, “Where can I safely add new ITequipment without overloading and potentially bringing down myfacility?” Calculating ARC is the answer.
Furthermore, what is the mean of redundancy? Redundancy is a system design in which acomponent is duplicated so if it fails there will be a backup.Redundancy has a negative connotation when the duplicationis unnecessary or is simply the result of poorplanning.
Similarly, what is the difference between redundancy and backup?
Redundancy is frequently confused withbackups. Whilst 'backup' is commonly about creatingcopies of data in preparation for a catastrophic loss,redundancy refers to more than just data storage. It focusesmore on the ability to provide a continuity of service, no matterwhat happens.
What is redundant structure?
A redundant or indeterminate structure hasmore structure than is absolutely necessary. So, if somepart of the structure is damaged or removed, thestructure will not necessarily fail or collapse, as anotherpart can bear the load of the damaged or missingpiece.

RAID is not a Backup RAID 1, conversely, does store at least twoinstances of every file distributed between two disks, therebyensuring that the failure of one of them will inflict no damage onthe other.Is RAID 1 a backup?
RAID is not a backup, it is hardwareredundancy for the sole purpose of providing uninterrupted businesscontinuity in the event of a hardware failure. Redundancy is notbackup.

No, if you have off-site backups then youdo not need it. If you cannot afford downtimethen some form of RAID is still recommended though, but formost people this is not an issue.
