With the cost of large drives being fairly cheap I use an external Sata caddy and keep one drive at home and another in a second location.  Each Drive has an image of the 'C' drive and then all the data is in another folder.  I use DVD RAM disks for some data as they are supposed to last longer and even then I copy them to new disks every 3 years.

I still use the PC I had for my Poser work up to a year ago and last week one drive stopped without warning.  All I could hear was the sickening tick of a dead drive, I suspect the drive is not spinning at all but thankfully the DVDs served their purpose.   The drive was 6 years old so I guess I have had my monies worth. 

Backing up can be a pain but sooner or later it bites if you don't. 

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
