[Help-tar] telling tar to take a break

[Lucas B. Cohen]

Hi,

I use tar to backup data to a tape drive which tends to overheat.

According to the documentation, there is no option to tell tar to sleep for
x amount of time every y gigabytes processed, or every z amount of time.

Is there an alternative program I could use which would allow me to do
something like that?
How hard would it be to add such feature to tar?
