I'm looking for a clean way to backup my laptop in part so before I apply any updates I have a clean backup to revert to if needed.
I have a / and /home filesystems in order to backup before I run a set of updates from yum I suspect I need to backup / separately this way I dont need to restore my 22Gig of documents in /home if an update breaks something.
In the past I've gone onto single user mode and used dd to backup my HD
I wonder if running tar with the proper flags to ensure the following would be as effective
1) restrict tar to the current(/) filesystem (i.e. disallow it from going off into /home)
2) ensure that tat picks up all the dot files
1) is the above tar scenario sufficient to protect me from yum update changes?
2) anyone have suggestions per specific tar commands that will do the operations specified above?
Thanks in advance
