I've done so much research into backup solutions and read so many other posts that I'm getting very frustrated and confused with all the options and non-starters, so hopefully someone here can point me in the right direction... MacPro at home, with an external drive holding 4TB of data. The backup scenario I imagine is - #1 - A local bootable backup for quick restore in case my hard drive melts. e.g. Carbon Copy. #2 - An off-site backup at the office for a round-trip restore in case the house melts. #3 - A cloud backup for a last-hope restore in case the city melts. e.g. CrashPlan. It's #2 I'm having a problem with. I don't want to keep transporting drives to and from the office, so I thought I could make an initial backup copy of the Mac + external drive at home, and install that backup drive(s) on the office network. Then I imagined there must be an elegant way of connecting securely from home to the drive at the office to keep the backup incrementally updated. Not so easy, apparently! I thought a NAS would be the obvious answer, but I don't understand enough of the technicalities to figure out which, if ANY, NAS offering would do the job, and which backup software would do the job, or even if this is a realistic scenario? Also, it seems to me that I need a secure internet connection - and the off-site drive needs to be encrypted, in case its borrowed by the evil maid. OR... maybe I can encrypt the files first and the NAS doesn't have to be secure? I'm getting lost... That in essence is the problem - How can I do incremental backups over the internet from home to office securely, and store those backups at the office securely? Thanks for reading this far... and thanks for any suggestions!
