I recently updated to a 128 GB solid state drive, and I've gotta say, I love the boot times and app load times, however I'm not keen on the increased possibility of spontaneous failure. I figure I've still got a few years on this thing, so I'm not majorly concerned about it, however I do want to get a static backup plan in place.
I've been considering the possibility of simply popping a MicroSD card into the side of my laptop and making an rsync script of my home folder (Linux Mint by the way) to backup to that card on startup/shutdown/whenever I feel is a good time to back it up. Apart from the initial sync, The actual amount of data that I figure I would backup regularly would be relatively tiny; minor changes to files here and there, occasionally adding new songs to my music folder, the only files that would see daily activity would be my source code folder.
I've never had an SD card fail on me, but then again going with "I've never" anecdotes is poor preparation for the worst. I don't think it's very likely my ssd and the backup MicroSD cards would fail at the exact same time, but I'm concerned about how often I would have to replace the MicroSD card. Would a 64 gb or so class 10 microsd card stand up to daily backup use?
