I-Data De-duplication iwubuchwepheshe obudumile nobudumile bokugcina obukhulisa amandla okugcina idatha.Kuqeda idatha engasadingeki ngokususa idatha eyimpinda kudathasethi, kusale ikhophi eyodwa kuphela.Njengoba kuboniswe emfanekisweni ongezansi.Lobu buchwepheshe bunganciphisa kakhulu isidingo sendawo yokugcina idatha ukuze kuhlangatshezwane nesidingo esikhulayo sokugcinwa kwedatha.Ubuchwepheshe be-Dedupe bungaletha izinzuzo eziningi ezingokoqobo, ikakhulukazi ezihlanganisa izici ezilandelayo:
| (1) | Hlangana nezidingo ze-ROI(Return On Investment)/TCO(Ingqikithi Yezindleko Zobunikazi); |
| (2) | Ukukhula okusheshayo kwedatha kungalawulwa ngokuphumelelayo; |
| (3) | Ukwandisa indawo yokugcina esebenzayo futhi uthuthukise ukusebenza kahle kokugcinwa; |
| (4) | Yonga isamba sezindleko zokugcina kanye nezindleko zokuphatha; |
| (5) | Londoloza umkhawulokudonsa wenethiwekhi wokudluliswa kwedatha; |
| (6) | Londoloza izindleko zokusebenza nezokulungisa njengesikhala, ukunikezwa kwamandla kagesi nokupholisa. |
Ubuchwepheshe be-Dedupe busetshenziswa kakhulu kuma-backups wedatha kanye namasistimu okugcina kungobo yomlando, ngoba kunedatha eminingi eyimpinda ngemva kokulondoloza okuningi kwedatha, okufanele kakhulu kulobu buchwepheshe.Eqinisweni, ubuchwepheshe be-dedupe bungasetshenziswa ezimeni eziningi, okuhlanganisa idatha ye-inthanethi, idatha eseduze, kanye nezinhlelo zokugcina idatha ungaxhunyiwe ku-inthanethi. Ingasetshenziswa ezinhlelweni zefayela, abaphathi bevolumu, i-NAS, kanye ne-sans.Dedupe ingasetshenziswa futhi ekubuyiseleni inhlekelele yedatha, ukudluliswa kwedatha nokuvumelanisa, njengoba ubuchwepheshe bokucindezelwa kwedatha bungasetshenziselwa ukupakishwa kwedatha.Ubuchwepheshe be-Dedupe bungasiza izinhlelo zokusebenza eziningi ukunciphisa ukugcinwa kwedatha, ukulondoloza umkhawulokudonsa wenethiwekhi, ukuthuthukisa ukusebenza kahle kokugcinwa, ukunciphisa iwindi lokulondoloza, nokulondoloza izindleko.
I-Dedupe inobukhulu obubili obuyinhloko: izilinganiso ze-deduplocation nokusebenza.Ukusebenza kwe-Dedupe kuncike kubuchwepheshe bokusebenzisa obuthile, kuyilapho izinga le-Dedupe linqunywa izici zedatha ngokwayo namaphethini ohlelo lokusebenza, njengoba kuboniswe kuthebula elingezansi.Abathengisi besitoreji okwamanje babika amanani okuphinda asuka ku-20:1 kuya ku-500:1.

I-Dedupe Implementation Points
Izinto ezihlukahlukene kufanele zicatshangelwe lapho kwakhiwa noma kusetshenziswa ubuchwepheshe be-Dedupe, njengoba lezi zici zithinta ngokuqondile ukusebenza nokusebenza kwayo.
| (1) | Ini | Iyiphi idatha eyehliswa isisindo? |
| (2) | Nini | Isisindo sizosuswa nini? |
| (3) | Kuphi | Kuphi ukuqedwa kwesisindo? |
| (4) | Kanjani | Indlela yokunciphisa isisindo? |
I-Dedupe Key Technology
Inqubo yokuphindaphinda uhlelo lwesitoreji ngokujwayelekile yile: okokuqala, ifayela ledatha lihlukaniswe ngeqoqo ledatha, kubhulokhi ngayinye yedatha ukubala izigxivizo zeminwe, bese kususelwa kumagama angukhiye wokusesha we-Hash, ukufanisa kubonisa idatha yamabhulokhi wedatha ephindwe kabili, igcina kuphela inombolo yenkomba yedatha ye-block, ngaphandle kwalokho kusho ukuthi i-data block iyona kuphela ingxenye entsha, ukugcinwa kwedatha ye-data block bese udala i-meta yolwazi yesistimu ehambisanayo nesistimu yokugcinwa kwedatha. yeqoqo lemethadatha ye-FP.Lapho ufunda ifayela, qala ufunde ifayela elinengqondo, bese ngokusho kokulandelana kwe-FP, khipha ibhulokhi yedatha ehambisanayo ohlelweni lokugcina, ubuyisele ikhophi yefayela elingokwenyama.Kungabonakala kusukela enkambisweni engenhla ukuthi ubuchwepheshe obuyinhloko be-Dedupe buhlanganisa ngokuyinhloko ukuhlukaniswa kwedatha yedatha yefayela, i-data block yeminwe yokubala kanye nokubuyiswa kwedatha.
(1) Isegimenti yebhulokhi yedatha yefayela
(2) Ukubalwa kwezigxivizo zeminwe zokuvimba idatha
(3) Ukubuyiswa kwebhulokhi yedatha
