Rich, My apologies for not being clear. What you describe is exactly what I have and want to accomplish. * 1 TB drive just for OS - currently a fresh install of Ubuntu 20.04 with nothing in /home/mark * 4TB drive holds the back up of home/mark - i.e. all "my stuff" (about 2.1 TB). I want to just keep adding to this backup of my old /home/mark directory. I only have the old OS stuff on the 4 TB drive to get the configuration files as needed. For example, I moved the etc/hosts file from the 4TB drive to the 1 TB drive so I have all my remote and local connections working. As I add more applications (e.g mysql) to my new OS drive, I want the old config files around to see what mods I made over the years. There are also scripts I wrote over time to automate some of my tasks, and I want to have access to them as I slowly "rebuild" my system.
My old system had the 1 TB drive and a 2 TB drive in a lvm (because I had more than 2 TB of stuff I was working on), so when the upgrade failed, I arrived at this point in time. Plus, I was running out of space in the 3 TB lvm, and Amazon had a reasonable sale price on a 4 TB SSD. ;) The point of my question was to get opinions on which is better and why, * mounting the home/mark directory on the 4 TB drive using bind to /home/mark on the 1 TB drive * or sym-link home/mark on the 4 TB drive to /home/mark on the 1 TB drive. I hope that clarifies it!
