The term ‘offline backup’ refers to any form of data storage that is both local and offline. This includes, but is not limited to, DVDs, CDs, Blu-ray, tape drives, external hard drives, USB thumb drives, and memory cards.
While each form has its particular advantages and disadvantages, there are benefits and drawbacks to the backup type as a whole.
Advantages of offline backup
Fast backup and restore
While uploading or restoring 200 GB worth of data is a time-consuming task no matter the backup type, offline data storage definitely has the edge. Its upload and restoration speeds are almost always going to be faster than that of online data storage, whose backup speed is almost entirely dependent on the strength of your Internet connection.
Nearly everyone keeps their offline backup readily at hand around the home or office. All it takes is for you to hook up your hard drive or plug in your USB stick and your data will start backing up in a snap.
The majority of offline backup media is small and lightweight enough to be conveniently stored in a desk drawer, or popped into a backpack to be carried around for safety purposes.
So long as they are not network drives with an internet connection, your offline backup is safe from cyber security breaches—a rarity in this day and age of ransomware, NSA snooping, and other security nightmares courtesy of the world wide web.
