I have a RHEL server which acts as the web server for all the users (around 1000 users). Now, I have a backup script which backs up the data (all data inside
/home folder) into an external HDD. This back up script is also in the
cron.daily so that the backup will happen on a daily basis.
Let us assume the RHEL web server crashed. I will build a new machine as a RHEL web server. I can paste the users' data that is already backed up in the external HDD into the new machine's
But for the 1000 users' to access their home directories in this new machine, I need to create the 1000 users again. Is there a way I can save that data too from the existing machine before crash? I know
/etc/groups will contain user related information. But if I save them, won't there be password issues?
