I would like to understand more about Complete GIT backup in Server on everyday or weekly basis. 
I have tried the @VonC fully and incremental backup script 'sbin/save_bundles', mentioned in this answer, which gives the following error.

Error message: 

./test.sh : line 7 : /home/.bashr : No such file or directory
./test.sh : line 69 : /home/sbin/usrcmd/get_hostname : No such file or directory
./test.sh : line 70 : get_hostname : command not found
./test.sh : line 71 : /home/sbin/usrcmd/get_fqn : No such file or directory
./test.sh : line 72 : get_fqn : command not found



Question: Is it possible to "add cold" or to "add heat" to systems?
Answer: The most important thing about feeling is that its relative and depends on the temperature of sensor point on skin. That's the reason we need thermometer to measure temperature with which everyone could agree.

Energy transfer is involved here, but it has very little to do with Amanda's feeling. Amanda's tongue and mouth was at high temperature due to initial sip which caused her to feel next sip cooler which was really cool due to addition of ice.

In case of spoon, spoon can't get hotter because heat of coffee (and some of heat of spoon) was consumed in melting ice. But, Amanda felt the spoon warmer because her fingers were relatively cold due to ice touch.
