Data recovery refers to techniques and processes used to regain access to data that has been lost due to corruption, accidental deletion, hardware failure, malware attacks, or other reasons. This can involve the use of specialized software, hardware tools, and sometimes professional services that analyze the storage medium to retrieve as much information as possible. In the context of web3 and blockchain technology, data recovery can also encompass efforts to retrieve lost cryptocurrencies or tokens resulting from lost private keys or wallet failures.
