Time Machine is great for keeping a local backup of your system, but if you're rather not worry about having a physical drive plugged in all the time you might want to consider an online solution instead. There are plenty of over-the-air (OTA) backup solutions, though not all are very affordable for a small smattering of system files. Fortunately, there are services like CrashPlan, which offers free back up to multiple place. Read on, and we'll show you how to set it all up.
For those of us who can’t afford pricey solid-state drives, but still need a speedy solution for storing data and transferring large files, RAIDs can fill the void--and provide much more storage capacity, dollar for dollar. When configured as a RAID 0, two drives working as one can offer impeccable performance for media, while a RAID 1 can offer a reliable backup solution as one hard drive mirrors the other. Now, hard drive manufacturers are offering Thunderbolt-compatible RAIDs to help bridge the gap between affordable storage solutions and Apple’s new high-speed technology, and both Western Digital and G-Technology have entered the market with their own Thunderbolt RAID offerings.

While Apple has not included a way to move these items back to the top of the Finder sidebar, there is a way to get some of the items at the top for easy access.
