Take a look at footage, plus images from the TV series "Altered Carbon", based on the 2002 'cyberpunk' science fiction novel by author Richard K. Morgan, premiering February 2, 2018 on Netflix:

"Only the wealthy are able to acquire replacement bodies on a continual basis. The long-lived are called 'Meths', a reference to the Biblical figure 'Methuselah'. The very rich are also able to keep copies of their minds in remote storage, which they update regularly. This ensures that even if their stack is destroyed, they can be resleeved.
"Then a Meth named 'Bancroft' apparently commits suicide. When he is resleeved and his destroyed stack restored, its 48-hour back-up schedule has no memories of the previous two days. Convinced he was murdered, Bancroft hires 'Takeshi Kovacs' to investigate..."
