The warmly cool, clear, ringing, perfumed, overflowing, redundant days, were as crystal goblets of Persian sherbet, heaped up —flaked up, with rose-water snow.

It is allowed, that senates and great councils are often troubled with redundant, ebullient, and other peccant humours; with many diseases of the head, and more of the heart; with strong convulsions, with grievous contractions of the nerves and sinews in both hands, but especially the right; with spleen, flatus, vertigos, and deliriums; with scrofulous tumours, full of fetid purulent matter; with sour frothy ructations: with canine appetites, and crudeness of digestion, besides many others, needless to mention.

The result is massacre; not, however, without its advantages, as it eliminates the more brutal and troublesome of the Isosceles; and by many of our Circles the destructiveness of the Thinner Sex is regarded as one among many providential arrangements for suppressing redundant population, and nipping Revolution in the bud.

The Typee girls devote much of their time to the dressing of their fair and redundant locks.

The perfect swarm of busily engaged persons moving about noiselessly; the multitude of guests, — who were, however, even less numerous than the servants who waited on them, — the myriad of exquisitely prepared dishes, of gold and silver vases; the floods of dazzling light, the masses of unknown flowers of which the hot-houses had been despoiled, redundant with luxuriance of unequaled scent and beauty; the perfect harmony of the surroundings, which, indeed, was no more than the prelude of the promised fete , charmed all who were there; and they testified their admiration over and over again, not by voice or gesture, but by deep silence and rapt attention, those two languages of the courtier which acknowledge the hand of no master powerful enough to restrain them.

Mr Partridge acted for some time on the defensive only; indeed he attempted only to guard his face with his hands; but as he found that his antagonist abated nothing of her rage, he thought he might, at least, endeavour to disarm her, or rather to confine her arms; in doing which her cap fell off in the struggle, and her hair being too short to reach her shoulders, erected itself on her head; her stays likewise, which were laced through one single hole at the bottom, burst open; and her breasts, which were much more redundant than her hair, hung down below her middle; her face was likewise marked with the blood of her husband: her teeth gnashed with rage; and fire, such as sparkles from a smith’s forge, darted from her eyes.

He was a small, short, youngish man, sprinkled all over his face with freckles, and wearing redundant yellow hair.

Unless you adopted the opinion of certain observers of the human heart, and thought that the chevalier had the voice of his nose, his organ of speech would have amazed you by its full and redundant sound.

Nothing told me then that she, a few years hence, would be the wife of one entirely unknown to me as yet, but destined hereafter to become a closer friend than even herself, more intimate than that unmannerly lad of seventeen, by whom I was collared in the passage, on coming down, and well-nigh jerked off my equilibrium, and who, in correction for his impudence, received a resounding whack over the sconce, which, however, sustained no serious injury from the infliction; as, besides being more than commonly thick, it was protected by a redundant shock of short, reddish curls, that my mother called auburn.

And by hideous con- trast, a redundant orator was making a speech to another gathering not thirty steps away, in fulsome laudation of «our glorious British liberties!»

Was it Hafiz or Firdousi that said of his Persian Lilla, She was an elemental force, and astonished me by her amount of life, when I saw her day after day radiating, every instant, redundant joy and grace on all around her.

So spake the Enemie of Mankind, enclos’d In Serpent, Inmate bad, and toward EVE Address’d his way, not with indented wave, Prone on the ground, as since, but on his reare, Circular base of rising foulds, that tour’d Fould above fould a surging Maze, his Head Crested aloft, and Carbuncle his Eyes; With burnisht Neck of verdant Gold, erect Amidst his circling Spires, that on the grass Floted redundant: pleasing was his shape, And lovely, never since of Serpent kind Lovelier, not those that in ILLYRIA chang’d HERMIONE and CADMUS, or the God In EPIDAURUS; nor to which transformd AMMONIAN JOVE, or CAPITOLINE was seen, Hee with OLYMPIAS, this with her who bore SCIPIO the highth of ROME.

I had a shower thought of my own this morning, in the shower. Like a gentleman. Redundancy, as we understand it in this industry, isn’t.

All the online dictionary I’ve read equates redundancy with being superfluous, unnecessary, or surplus to requirements. Collins takes it a step further by also claiming it can mean:

duplicated or added as a precaution against failure, error, etc

This is what I understand redundancy to mean. I want offsite backups, multiple copies of data in a RAID or OpenZFS pool, and read replicas of my live databases. These are all forms of redundancy, because they can improve performace by spreading load, continue to operate in a degraded state and, most critically, recover from loss.

If we consider redundancy to be an essential requirement of a system then, is the existence of said redundant data not redundant? Anyone who claims backups are redundant in the traditional English use of the term isn’t qualified to design or operate computer systems!

Much as my old boss said that anything that isn’t documented doesn’t exist, I’d argue any data without redundancy is ephemeral. If your system can’t tolerate that, redundancy is therefore a requirement.

Each industry has its own vocabulary and nomenclature that may conflict with definitions in other spheres. It’s why nerds get up in arms about the word hacker, despite violent and negative connotations predating our use (Jack the Ripper wasn’t hacking people up to fix them in an innovative way). I wonder what other terms don’t just have different meanings, but are polar opposites?

I always thought OSPF sounded like a laundry detergent.

It’s an adjective I think. As in «The genetic code can be said to be (blank) because multiple codons can code for the same amino acid» or «My database is (blank) because it keeps multiple copies of critical files in case one is corrupted»

Hint: «backup» isn’t the word I’m looking for.

Thanks folks.
