How does the type of storage device affect data recovery chances?

由人工智能和领英社区提供技术支持

Data recovery is the process of retrieving lost, deleted, or corrupted files from a storage device, such as a hard drive, SSD, USB flash drive, or memory card. Whether you accidentally formatted your disk, suffered a malware attack, or experienced a physical damage, you might wonder if you can recover your data and how. In this article, we will explain how data recovery works, what factors affect its success rate, and how different types of storage devices impact the recovery chances.

1 Data recovery basics

Data recovery is possible because when you delete a file, it is not erased from the disk immediately. Instead, the file system marks the space occupied by the file as available for new data, but the original data remains until it is overwritten by new data. Therefore, if you act quickly and avoid using the device, you might be able to recover the file using a data recovery software or service. However, there are no guarantees, as the file might be partially or completely overwritten, fragmented, or encrypted.

The type of storage device significantly impacts data recovery chances. Solid State Drives (SSDs) pose challenges due to wear leveling and complex data structures, potentially lowering success rates. Traditional Hard Disk Drives (HDDs) offer higher success rates as recovery tools navigate file systems more predictably. Factors influencing success include device health, encryption, and data fragmentation. For improved recovery, choose storage solutions based on the specific needs of data criticality. Regular backups, especially on reliable and proven platforms, remain crucial. Tailoring recovery strategies to storage types enhances the overall success of data recovery efforts.

Whilst many applications will have the means to recover data, such as a recycle bin, not having a backup and recovery solution can lead you into a world of pain. Often more than not, in-app recovery options give some protection, but what if something goes wrong and you cannot restore your data in full? If your data is within a database - how can you audit and validate the relationships to other data? Or should the worst happen - how would your business continue if you cannot access your data? This is why it is important to invest in a backup recovery solutions that allow: - Compliance with industry regulation/law - Allows you to restore your data to meet Recovery Time Objectives - Has audited security certification - Superior availability

Aus eigener Erfahrung bezüglich der Wiederherstellung der Daten gilt es, bereits vorab folgende Punkte zu berücksichtigen: - Trennen Sie Ihre Datensicherungsmedien nach kurz- (NVMe/SSD), mittel- (HDD) und langfristiger (Magnetband) Wiederherstellung - Verwenden Sie wenn m?glich keine Verschlüsselung und keine herstellerabh?ngigen Dateiformate - überprüfen Sie regelm??ig (+/- alle sechs Monate) die Lesbarkeit der Speichermedien - Daten, welche bei Verlust den Fortbestand des Unternehmens gef?hrden, sollten vom Netzwerk getrennt, auf Magnetb?ndern aufbewahrt werden. - Proben und trainieren Sie den Ernstfall, um eine reibungslose Wiederherstellung zu gew?hrleisten

2 Success rate factors

The success rate of data recovery depends on several factors, such as the cause and extent of data loss, the condition and quality of the storage device, the time elapsed since the deletion, and the method and tools used for recovery. Generally, the more severe the damage, the lower the chances of recovery. For example, if your device has physical damage, such as a broken circuit board, a scratched platter, or a burnt chip, you might need professional help to repair it before attempting data recovery. On the other hand, if your device is functional but has logical damage, such as a corrupted file system, a virus infection, or a bad sector, you might be able to recover some or all of your data using a software tool.

Erfahrungen aus der Praxis: - Backups auf abschaltbaren NAS-Systemen speichern - 3-2-1-1-0, drei Kopien auf zwei verschiedenen Medien an verschiedenen Orten, eine Kopie extern, eine Kopie offline und Null Fehlertoleranz im Sicherungsprozess. - Nutzen Sie Software, die sowohl die Ausführung der Datensicherung best?tigt, sowie den erfolgreichen Schreibvorgang verifiziert - Nutzen Sie Magnetb?nder – diese haben eine 100.000 mal h?here Datenintegrit?t als Diskspeicher, sind ein vom Netzwerk entkoppeltes Speichermedium und haben eine Nutzungsdauer von über 30 Jahren - Daten auslagern statt verschlüsseln- wenn die Ransomware die Schlüssel überschreibt sind die Daten verloren. - Wichtige Unternehmensdaten geh?ren auf Magnetband extern aufbewahrt

3 Storage device types

Another factor that affects data recovery is the type of storage device you use. Different storage devices have different architectures, technologies, and features that influence how data is stored, accessed, and deleted. For example, hard disk drives (HDDs) use spinning magnetic platters to store data, while solid state drives (SSDs) use flash memory chips to store data. HDDs are more prone to mechanical failures and physical damage, but they also have a higher chance of recovering deleted data, as they do not overwrite data as quickly as SSDs. SSDs are more resistant to shocks and vibrations, but they also have a lower chance of recovering deleted data, as they use a feature called TRIM to erase data permanently and optimize performance.

Berücksichtigen Sie bei Ihrer Entscheidung für ein Speicherger?t die Fehlertoleranz (Bit Error Rate) des Speichermediums: - HDD: BER 1x10 hoch 15 - SSD: BER 1x10 hoch 17 - LTO Tape: BER 1x10 hoch 20 Je h?her der Wert, umso geringer die Fehleranf?lligkeit. HDD, SSD & NVMe sind Random Access Medien und im Normalfall dauerhaft mit dem Netzwerk verbunden. Ihre Anf?lligkeit für mechanische, elektrische oder physische Sch?den ist hoch. LTO Tapes sind robuste, lineare Medien, bei denen entweder ein Lese- oder ein Schreibprozess ausgeführt wird. LTO Tapes haben keinen Motor, keine aufwendige Mechanik und sind nach der Nutzung vom Netzwerk entkoppelt.

4 Data recovery tips

If you want to increase your chances of data recovery, it is important to take the right steps. Stop using the device as soon as you notice data loss to prevent further damage and overwriting of data. Furthermore, do not attempt to repair or open the device unless you have the skills and tools to do so, as this could cause more harm than good and void your warranty. Additionally, use a reliable and reputable data recovery software or service, as free or unknown tools might contain malware or damage your data. Finally, backup your data regularly and store it on a separate device or cloud service to save yourself time, money, and stress in case of data loss. Ultimately, understanding how data recovery works, what factors affect its success rate, and how different types of storage devices impact the recovery chances can help you make informed decisions and take appropriate actions to recover your data.
