Thank you. Okay so, just to make sure, if I wanted to backup directory A and all sub directories, I would do `find -d A -print > file.txt`, and then `tar -cv -T file.txt -f backup.tar`? Also, will this work with the -M option. I apologize if these are basic questions, but I am new to this and I want to make sure I create these backups correctly.
Also, when extracting files, if I specify a specific file to extract, will tar parse everything before that entry in the file, or will it jump to the file it needs to extract?
