In computing, data recovery is a process of salvaging (retrieving) inaccessible, lost, corrupted, damaged or formatted data from secondary storage, removable media or files, when the data stored in them cannot be accessed in a normal way. The data is most often salvaged from storage media such as internal or external hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, magnetic tapes, CDs, DVDs, RAID subsystems, and other electronic devices. Recovery may be required due to physical damage to the storage devices or logical damage to the file system that prevents it from being mounted by the host operating system (OS).
The most common data recovery scenario involves an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive. This can be easily accomplished using a Live CD, many of which provide a means to mount the system drive and backup drives or removable media, and to move the files from the system drive to the backup media with a file manager or optical disc authoring software. Such cases can often be mitigated by disk partitioning and consistently storing valuable data files (or copies of them) on a different partition from the replaceable OS system files.
Another scenario involves a drive-level failure, such as a compromised file system or drive partition, or a hard disk drive failure. In any of these cases, the data is not easily read from the media devices.

Dalam komputasi, pemulihan data adalah proses penyelamatan (pengambilan) data yang tidak dapat diakses, hilang, rusak, rusak atau diformat dari penyimpanan sekunder, media atau file yang dapat dilepas, ketika data yang disimpan di dalamnya tidak dapat diakses dengan cara biasa. Data ini paling sering diselamatkan dari media penyimpanan seperti hard disk internal atau eksternal (HDD), hard disk solid state (SSD), flash drive USB, kaset magnetik, CD, DVD, subsistem RAID, dan perangkat elektronik lainnya. Pemulihan mungkin diperlukan karena kerusakan fisik pada perangkat penyimpanan atau kerusakan logis pada sistem file yang mencegahnya dipasang oleh sistem operasi host (OS).
Skenario pemulihan data yang paling umum melibatkan kegagalan sistem operasi, malfungsi perangkat penyimpanan, kegagalan logis dari perangkat penyimpanan, kerusakan atau penghapusan yang tidak disengaja, dll. (Biasanya, pada sistem single-drive, single-partition, single-OS), dalam hal ini tujuan utamanya adalah menyalin semua file penting dari media yang rusak ke drive baru lainnya. Hal ini dapat dilakukan dengan mudah menggunakan Live CD, banyak yang menyediakan sarana untuk memasang drive sistem dan drive cadangan atau media yang dapat dilepas, dan untuk memindahkan file dari drive sistem ke media cadangan dengan manajer file atau perangkat lunak pengarang disk optik . Kasus semacam itu sering dapat dikurangi dengan partisi disk dan secara konsisten menyimpan file data berharga (atau salinannya) pada partisi yang berbeda dari file sistem OS yang dapat diganti.
Skenario lain melibatkan kegagalan tingkat-drive, seperti sistem file yang terganggu atau partisi drive, atau kegagalan hard disk drive. Dalam semua kasus ini, data tidak mudah dibaca dari perangkat media.
