Bert is extreme. Such a waste talent in pediatrics. IT or Wall Street paying more plus year end bonus plus more excitements and heart racing moments comparable to trauma level 4 care. The major disadvantage is that Bert can not practice till in his 80s. I changed my mind, stick to medicine, even boring it is safer bet.
I am sorry to use the word redundancy not in an absolute term. My redundancy should mean cloning with differential upgrades. Even they are cloned, to be true redundancy needs to be real time. For local redundancy there is RAID or external hard drive software.
There many true sync program out there like sure sync, vice versa (60 bucks).. to copy any file changes to a clone computer. We are doing sync twice or more a day, during lunch time and after hours between computer 1 and 2 and once a day with computer 3. For the last 4 years I am using free Microsoft Synctoy to sync between AC backup and imported items folders. Imported folder is about 9 gig and sync time on our quad Xenon is about couple minutes at 50% CPU. For the remote computer 3, I use log me in to copy latest backup file and copy with overwritten option for imported items. Those sync tasks are much simple then texting, so any trusting person in the office can do it. I don't know if Server software have this sync function built in or not as I don't have experience with newer server software, so any question about Server OS needs to direct to Bert, Indy, James IT or Sandeep. My learning ability is diminishing to a point...
As I keep AC running in all three of them, I can do a quick test right away to see if they are working. even switching computer 1, 2. Doesn't matter what happened, my doc can keep on working, I can fix most of problem in minutes. Switching in computer 2 if 1 crash and do the fixing later. PC 2 is half a day behind PC 1. I don't even bother with automatic sync because then I'd be out of my three meals a day job.
I don't know but seems when you have too many back up computers running, rarely any problems almost like a warranty, but as soon as the warranty expired....
