Otu esi emekọrịta sava/Webụsaịtị Apache abụọ site na iji Rsync

Enwere ọtụtụ nkuzi dị na webụ iji enyo ma ọ bụ were ụzọ dị iche iche ndabere faịlụ webụ gị, ebe a, m na-eke akụkọ a maka ntụaka ọdịnihu m na ebe a, m ga-eji iwu Linux dị mfe ma dị iche iche mepụta ndabere nke weebụsaịtị gị. Nkuzi a ga - enyere gị aka ịmekọrịta data n'etiti sava weebụ gị na Rsync.

Ebumnuche nke ịmepụta enyo nke sava Weebụ gị na Rsync bụ ma ọ bụrụ na sava weebụ gị daa, ihe nkesa ndabere gị nwere ike weghara iji belata oge webụsaịtị gị. Ụzọ a nke ịmepụta nkwado ndabere na mpaghara weebụ dị ezigbo mma ma dị irè maka obere ụlọ ọrụ weebụ dị obere na ọkara.

Uru nke imekọrịta sava webụ

Uru ndị bụ isi nke ịmepụta ndabere sava weebụ na rsync bụ ndị a:

  1. Rsync na-emekọrịta naanị bytes na ngọngọ data ndị agbanweela.
  2. Rsync nwere ike ịlele na hichapụ faịlụ na akwụkwọ ndekọ aha na sava ndabere nke ehichapụrụ na sava weebụ bụ isi.
  3. Ọ na-elekọta ikike, nwe na njirimara pụrụ iche ka ọ na-edegharị data n'ime anya.
  4. Ọ na-akwado SSH protocol ịnyefe data n'ụzọ ezoro ezo ka e wee jide n'aka na data niile adịghị mma.
  5. Rsync na-eji usoro mkpakọ na decompression mgbe ọ na-ebufe data nke na-eri obere bandwit.

Otu esi emekọrịta sava weebụ Apache abụọ
