If you\u2019re already using Backblaze or another cloud backup solution, you\u2019re well on your way to bulletproof data storage security. So why clutter up your desktop with an external hard disk drive and its bulky cable if you don\u2019t have to? Well, there are still a few reasons to consider. Read on for details.<\/p>\n

Primary Backup<\/h2>\n

My backup strategy<\/a> is to have both a primary and secondary backup system as part of my 3-2-1 backup plan<\/a>. The primary backup is the hard drive that sits on my desk. I\u2019m a Mac person so I set up a Time Machine backup (software made by Apple, included with OS X) to an external USB 3 drive, which I connect periodically to make sure I have a timely backup. If you\u2019re a Windows user, Windows has its own built-in backup software<\/a>. There are plenty of other third-party apps you can install for either platform too.<\/p>\n

The advantage to using a hard drive as your primary backup is the immediacy of access. If you need to rebuild a complete directory or restore just a single file or document, it\u2019s right there. You don\u2019t need an internet connection or even a working network\u2014just the computer, the hard drive, and the cable to connect them is enough to get your file back.<\/p>\n

\n\n\n\n
Figuring out what kind of hard drive to use is another story. Different computers have different peripheral connections. For a rundown, check out “What\u2019s the Diff: Thunderbolt and USB.”<\/a><\/em><\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Cloning<\/h3>\n

Restoring a file or directory is one thing, but it\u2019s something else all together when the computer stops working because an essential system directory or library has gotten corrupted, damaged, or overwritten. Or when the computer\u2019s primary boot drive fails, as hard drives sometimes do.<\/p>\n

\n\n\n\n

When you\u2019re staring at a flashing question mark or a blue screen, you know you\u2019re in for hours of troubleshooting fun. That\u2019s hours of troubleshooting you can avoid with a clone<\/a>. A cloned drive is a bit for bit copy of your regular hard drive. In the event of a major problem, the cloned drive can be used in place of the computer\u2019s boot drive to keep you working.<\/p>\n

External Storage<\/h3>\n

Sometimes the amount of space you have on your computer\u2019s boot volume just isn\u2019t enough. Especially as more of us have gotten laptops, and companies have traded big hard drives for much speedier (but usually smaller) SSDs, we find ourselves with less and less space for the files we amass in work and life.<\/p>\n

External hard drives make a convenient way to store those files without having to jockey for space on your computer\u2019s boot drive. If you\u2019re working with big data sets\u2014video files, for example, multitrack audio, any kind of multimedia, large data sets that you\u2019re doing analysis on, or any kind of archival\u2014chances are you\u2019ll want to put that on an external hard drive<\/a> rather than relying only on what you can cram on your computer and put in the cloud.<\/p>\n

Secondary Backup<\/h3>\n

I\u2019ll reverse the question I asked at the outset: If you\u2019re already using a primary backup system, why bother with a secondary system at all? The phrase \u201cdon\u2019t put all your eggs in one basket\u201d comes to mind. Even careful management of your backup system won\u2019t overcome the occasionally unforeseen and unforeseeable.<\/p>\n

Backblaze is my<\/em> secondary backup solution<\/a>. I don\u2019t depend on it exclusively to keep my files safe, but I know they\u2019re there. And on the occasions I\u2019ve had to restore files, I\u2019ve gone to Backblaze more than once to grab something I either couldn\u2019t find or couldn\u2019t find easily with my primary backup.<\/p>\n

Whether you use Backblaze, one of our competitors, or if you\u2019ve cobbled together your own cloud backup system using Dropbox, Google Drive, or other means, secondary backup provides you with a very important added layer of protection. If anything happens to your data and your primary backup system\u2014even a natural disaster or a fire\u2014keeping your data off-site in a secure data center is a good plan.<\/p>\n

How\u2019s Your Backup Set Up?<\/h2>\n

Enough about my backup routine. I want to know more about yours. Tell me how you\u2019re backing up your computer. Or are you still confused? Have a question?
