Just 4 or 5 days ago, I had to recover the linuxcnc configs from a backup of the pi3, making a scratch dir here at home, then scanned my database for the last level0 of the pi3b, pulled that out with amrecover then copied what I needed back to the rpi4 now living in my Sheldon Lathes control box. File moving done by an old friend, mc, and sshfs mounts. Totally painless, and all the magic I had written on the pi3 is now running considerably better on the pi4. Saves me from having to re-invent at least 2 wheels you won't find on any other cnc lathes, that took me over 6 months to develop. > It doesn't do magic, like Winders does, though.

I don't use tapes, but virtual tapes, 60 of them on a 2TB drive, and which are nothing but a directory entry on the disk. So I have backups up to 60 days old instantly available. Using tapes nearly bankrupted me as the hard drives will outlast tapes by at least 1000/1. Amanda ages out the old ones and reuses the space on the drives with no drama. This wouldn't do for business records of course, but is ideal for a home workshop. I started out with a 1T drive but after several years it was getting crowded, so it got replaced with a 2T about a year back. The retired 1T has nearly 80,000 spinning hours on it with a perfect bill of health from smartctl.
