![]() ![]() SSD is faster, more durable, and more reliable than HDD. Most hard drives do not support password protection, so if your hard drive is lost or stolen, anyone with access to it can access your information. Therefore, you need to be extra careful when using hard drives for backups. The disadvantage of HDD is that it is easily damaged or crashed. The biggest advantage of external hard drives over U disks is their larger storage space, which makes them great backup devices for enterprises and long-term backups. There are two main types of external hard drives: HDD (hard drive) and SSD (solid-state drives). However, if you use flash drives on different computers, you may spread viruses from one computer to another and infect files stored in them. The main purpose of flash drives is to transfer files from one device to another. It is very easy to store, retrieve and manage data on flash drives. USB Flash DrivesĪ USB flash drive is a plug-and-play portable storage device that uses non-volatile memory to store data. In addition, the SD card is easily damaged and you may lose the data stored in it.Īlso see: 3 Ways to Back up SD Card to Computer for Data Protection 4. However, SD cards are more expensive than hard drives, CDs, or DVDs. They are used to back up documents, pictures, videos, or audio files. They are widely used to store small amounts of data on mobile phones, cameras, and computers. The advantages of SD cards are that they are small, portable, and can easily access data. If your laptop or desktop computer does not have an optical drive or does not support all drive formats, this may not be suitable for you. Discs require special hardware/software to read and write. However, optical discs are more susceptible to damage or scratches, and the data on the optical discs can easily become unreadable. The data on the optical disc is read and written by laser, so there is less wear during the reading and writing process. The main advantages of optical discs ( CDs/ DVDs/ Blu-ray) are inexpensive and easy to carry, so they are usually used for system backup and recovery.

Since the tape is a sequential access device, finding and restoring individual files can be slow and cumbersome. Besides, the tape drive can be easily removed and stored offsite, so the data stored on it is protected from any hardware failure, damage, theft, or natural disasters.Īlthough tape backups are feasible, they are slow and costly. The main advantage of tape drives is that they are reliable since the data stored on the tape drive can be safely read even after decades of storage. Tape drives are one of the computer backup devices. Then, we will provide a full introduction to these computer backup devices. There are many data storage devices on the market, such as tape drives, optical drives, SD cards, hard drives, and so on. When you decide to back up data, the first thing to choose is the storage device or backup media to use for the backup. Thus, it’s necessary to back up your data in advance. Many users encounter data loss situations because of system failure, virus/malware/ransomware attacks, etc. How to Back up Data to Computer Backup Devices.This post from MiniTool introduces different types of computer backup devices and how to back up your data to them. These types of backups are often performed by backup software because they can be done frequently due to their small size and fast backup time.To protect your computer data, it’s recommended to back up your data to external devices. The difference is that incremental backups will back up any changed data since the last backup, whether it was a full, differential, or incremental backup. Incremental backups: Like a differential backup, incremental backups also only back up data that has been changed or added since the last backup.Because of this, differential backups can be performed much more quickly than a full backup. Differential backups: With a differential backup, you’re only backing up files that have changed or have been added since your last full backup. ![]() A full backup is recommended when you’re backing up your data for the first time. Because of this, the process could take many hours depending on the size of the data. Full backups: This method backs up every single file on your device.Depending on the size of the data you’d like to protect and the frequency with which you’d like to back it up, you can decide between these three data backup options: When deciding on a backup data storage strategy, there are different types of data backups you can perform to help protect your personal data. ![]()
