My Mac has a lot of stuff on it, and it’s configured exactly as I want it. I would hate to lose the drive or have it stolen and be out of luck. I do use Time Machine to take regular backups of the files, even though my capsule died and I had to replace it with a 5TB drive. The concern I have with Time Machine is that it’s not a bit-for-bit copy of my hard drive that I can boot from if needed. Enter Carbon Copy Cloner. There are a few options out there to choose from, Super Duper being one of those, but after trying a few of them I landed on CCC. Cloning my drive gives me peace of mind, and the program monitors my HDD for file modifications, if the modifications == 1GB, then it performs a “sync” of sorts. Basically it’s another backup, but only the changes. That happens many times during the day, which is pretty awesome.
The only thing I wish this did was encrypt the data and require a key. In case someone snagged my external drive, it would be useless. For now I lock the drive in the hidden safe located in my office whenever I leave the house. But it would be great if that was something I did not have to do.
