Umgqomo wokuphinda usebenzise kabusha ubungomunye wezinto ezinhle kakhulu ezisunguliwe ekusebenziseni ikhompyutha. Ngenxa yalolu doti, singathola noma yiliphi ifayela esilisuse ngephutha noma ngokuqonda kodwa esifuna ukulibuyisa. Kodwa-ke, kunabasebenzisi abaningi abanomkhuba wokukuchitha nsuku zonke njalo lapho beyibona igcwele amaphepha, okubandakanya nami, sisusa konke ukusebenza okusinikeza kona, ikakhulukazi uma singasebenzisi i-Time Machine ukugcina ikhophi yawo wonke amafayela nemibhalo esiyigcine ku-Mac yethu.
Njalo lapho sisusa ifayela kudrayivu yethu ye-USB, ifayili liya kumgqomo wokuphinda usebenzise indawo osebenzisa isikhala esingasisebenzisela noma yini enye. Uma sihlala sisebenza ngamadrayivu angaphandle, kungenzeka ukuthi ngokuhamba kwesikhathi, futhi uma singathululeli umgqomo wokuphinda usebenzise kabusha ihora ngalinye, uzoqala ukuthatha isikhala esibalulekile kwi-hard drive yethu, kuze kudlule izinsuku namafayela agcinwe kuwo asuswe ngokuzenzakalela. Uma sifuna udoti wethu ugcwalise kuphela amafayela avela kwi-hard drive yethu, ukuvimbela amafayela esiwasusayo ekugcwaliseni udoti wethu, singasebenzisa i-Curb.
I-Curb isicelo esincane samahhala esivumela ukuthi sikhiphe zonke izinto kudoti wethu okuyi-USB drive, noma ngabe yinduku ye-USB noma i-hard drive. Umsebenzi ulula kakhulu, ngoba uma sesisusile amafayela, kufanele nje sihudule isithonjana seyunithi ku-Curb, ukuze izenzakalelayo susa kudoti zonke izinto ezikopishwe kudoti ku-Mac yethu uma kwenzeka sifuna ukuzilulama kamuva. I-Curb isekelwa njenge-macOS 10.6 futhi iyatholakala ukulanda mahhala ekhasini lonjiniyela.
