Abstrak
Tujuan penelitian adalah merancang sebuah aplikasi backup data yang digunakan untuk menganalisis, meningkatkan kinerja dalam mem-backup data dan memperlancar kegiatan belajar atau bisnis individu atau kelompok yang mengalami kesulitan dalam mem-backup data. Metode penelitian yang dilakukan dengan menggunakan kuisioner, studi lapangan, studi laboratorium dan studi kepustakaan dari buku-buku yang berhubungan dengan skripsi ini. Serta metode perancangan sistem terdiri dari perencanaan dan pemilihan sistem, analisis sistem, desain sistem, serta implementasi dan operasi sistem. Hasil yang dicapai dalam penelitian adalah sebuah aplikasi backup data yang menyediakan backup data dan sistem sharing yang berguna untuk membantu dan memperlancar kegiatan belajar atau bisnis individu atau kelompok sehingga individu atau kelompok dapat melanjutkan pekerjaan mereka jika kehilangan informasi atau data yang krusial. Kesimpulan yang didapatkan adalah dengan adanya aplikasi ini individu atau kelompok dapat dengan mudah membackup data yang bersifat krusial kapan saja dan dimana saja.
