linux rsync\u00a0 stands for remote sync which was written by Andrew Tridgell<\/a> and Paul Mackerras back in 1996. It\u2019s one of the most used and power \u2018tools\u2019 in the UNIX world and almost a standard for syncing data. Most Linux distributions have rsync pre-installed, but if it\u2019s not there you can install the \u2018rsync\u2019 package for your distribution.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t\t\t\t\tRsync is an extremely powerful tool and does more than just make copies of your files on your system. it also synchronize files on two directories on the same Server; or synchronize files and\/or directories on two different systems on the same network.\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

  • rsync<\/strong>\u00a0faster than\u00a0scp<\/strong>\u00a0(Secure Copy) ,because\u00a0rsync<\/strong>\u00a0uses remote-update protocol which allows to transfer just the differences between two sets of files. First time rysnc copies the whole content of a file or a directory from source to destination then the next time rsync copies only the changed blocks and bytes to the destination.<\/li>\n
  • Rsync consumes less bandwidth because it uses compression and decompression method while sending and receiving data both ends.<\/li>\n
  • Rsync Supports copying links, devices, owners, groups and permissions.<\/li>\n
  • its support remote copy.<\/li>\n<\/ul>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
