I have been wondering what others are doing for their personal backup strategys. I currently have 4 Windows PCs and 2 Macs that are used between myself, my kids and my wife. We all back up to a LaCie 2 Big device that consists of 1TB of mirrored storage. Everyone has their own directories for our personal files. I personally have over 10,000 digital photos and over 30,000 mp3 files so the loss of the information on these disks would be pretty bad to say the least. I have thought about replicating everything on the LaCie to some sort of online cloud storage like Carbonite or Backblaze, but I do not like the thought of having all of my personal information out there out of my personal possession, so this is not an option for me personally. I recently purchased a portable 1TB UBS drive, which is small and portable to replicate everything that is on my LaCie to. This would allow me to travel with this drive and still have access to everything I need. I am not clear on is if there is some sort of syncing software that anyone could recommend that would allow any changes made on either the Portable USB drive or the LaCie drive to sync with each other. So if a file changes on the LaCie drive those changes sync automatically to the Portable USB drive and if for example I delete a file on the portable USB drive that file is then deleted on the LaCie drive. If you have a better suggestion I am open to those as well. Thanks in advance for your feedback and input.
