Ukususwa kwedatha ubuchwepheshe bokugcina obudumile nobudumile obuthuthukisa umthamo wesitoreji. Bususa idatha engafuneki ngokususa idatha ephindaphindiwe kusethi yedatha, kushiye ikhophi eyodwa kuphela. Njengoba kuboniswe esithombeni esingezansi. Lobu buchwepheshe bunganciphisa kakhulu isidingo sendawo yokugcina idatha ukuze kuhlangatshezwane nesidingo esikhulayo sokugcina idatha. Ubuchwepheshe be-Dedupe bungaletha izinzuzo eziningi ezisebenzayo, ikakhulukazi okuhlanganisa izici ezilandelayo:
| (1) | Hlangana nezidingo ze-ROI (Imbuyiselo Ekutshalweni Kwezimali)/TCO (Izindleko Zobunikazi Eziphelele); |
| (2) | Ukukhula okusheshayo kwedatha kungalawulwa ngempumelelo; |
| (3) | Khulisa isikhala sokugcina esisebenzayo futhi uthuthukise ukusebenza kahle kwesitoreji; |
| (4) | Londoloza izindleko zokugcina kanye nezindleko zokuphatha; |
| (5) | Londoloza i-bandwidth yenethiwekhi yokudluliswa kwedatha; |
| (6) | Yonga izindleko zokusebenza nokugcinwa kwesikhala, ukunikezwa kukagesi kanye nokupholisa. |
Ubuchwepheshe be-Dedupe busetshenziswa kabanzi ezinhlelweni zokulondoloza idatha kanye nokugcina idatha, ngoba kunedatha ephindaphindwayo eminingi ngemva kokwenza amakhophi amaningi edatha, okuyinto efanele kakhulu lobu buchwepheshe. Eqinisweni, ubuchwepheshe be-dedupe bungasetshenziswa ezimweni eziningi, kufaka phakathi idatha eku-inthanethi, idatha eseduze, kanye nezinhlelo zokugcina idatha ezingaxhunyiwe ku-inthanethi. Bungasetshenziswa ezinhlelweni zamafayela, kubaphathi bevolumu, kwi-NAS, kanye nakuma-sans. I-Dedupe ingasetshenziswa futhi ekubuyiseleni idatha enhlekeleleni, ekudlulisweni kwedatha nasekuvumelaniseni, njengoba ubuchwepheshe bokucindezela idatha bungasetshenziswa ekupakisheni idatha. Ubuchwepheshe be-Dedupe bungasiza izinhlelo zokusebenza eziningi ukunciphisa ukugcinwa kwedatha, konge i-bandwidth yenethiwekhi, kuthuthukise ukusebenza kahle kwesitoreji, kunciphise iwindi lokulondoloza, futhi konge izindleko.
I-Dedupe inezilinganiso ezimbili eziyinhloko: izilinganiso zokwehliswa kanye nokusebenza. Ukusebenza kwe-Dedupe kuncike kubuchwepheshe bokusebenzisa obuthile, kuyilapho izinga le-Dedupe linqunywa izici zedatha uqobo kanye namaphethini ohlelo lokusebenza, njengoba kuboniswe kuthebula elingezansi. Abathengisi besitoreji okwamanje babika amazinga okwehliswa asukela ku-20:1 kuya ku-500:1.

Amaphuzu Okuqalisa Okunciphisa
Izici ezahlukahlukene kufanele zicatshangelwe lapho kuthuthukiswa noma kusetshenziswa ubuchwepheshe be-Dedupe, njengoba lezi zici zithinta ngqo ukusebenza kwayo kanye nokusebenza kwayo kahle.
| (1) | Ini | Yimiphi idatha encishisiwe isisindo? |
| (2) | Nini | Isisindo sizosuswa nini? |
| (3) | Kuphi | Kuphi ukususwa kwesisindo? |
| (4) | Kanjani | Unganciphisa kanjani isisindo? |
Ubuchwepheshe Bokhiye be-Dedupe
Inqubo yokwehliswa kwesistimu yokugcina ngokuvamile yile: okokuqala ifayela ledatha lihlukaniswe ngesethi yedatha, yebhulokhi ngayinye yedatha ukubala izigxivizo zeminwe, bese kusekelwe kumagama angukhiye okusesha e-Hash, ukufanisa kubonisa idatha yamabhulokhi edatha aphindaphindwayo, kugcina kuphela inombolo yenkomba yebhulokhi yedatha, ngaphandle kwalokho kusho ukuthi ibhulokhi yedatha yiyona kuphela ingxenye entsha, isitoreji sebhulokhi yedatha futhi idale ulwazi olufanele lwe-meta. Ngakho-ke, ifayela elingokoqobo ohlelweni lokugcina lihambisana nokumelwa okunengqondo kwesethi yemethadatha ye-FP. Uma ufunda ifayela, qala ufunde ifayela elinengqondo, bese ngokusho kochungechunge lwe-FP, khipha ibhulokhi yedatha ehambisanayo ohlelweni lokugcina, ubuyisele ikhophi yefayela elingokoqobo. Kungabonakala enkambisweni engenhla ukuthi ubuchwepheshe obubalulekile be-Dedupe buhlanganisa kakhulu ukuhlukaniswa kwebhulokhi yedatha yefayela, ukubalwa kwezigxivizo zeminwe yebhulokhi yedatha kanye nokubuyiswa kwebhulokhi yedatha.
(1) Ukuhlukaniswa kwefayela lokuvimba idatha
(2) Ukubalwa kweminwe yebhulokhi yedatha
(3) Ukubuyiswa kwedatha
