I would like to backup my personal user settings (updated applications & libraries, drivers (nvidia), and esp. the gnome desktop settings, panels, etc as I spent some time configuring these).
Would also like to backup the system configuration (network, drivers, etc.) files.
Questions are (being from a Windows background)
What should I backup? (which directories/files) & how to restore them later, after re-install of system?
How can I backup (using what application)? (Will a simple copy (after login as ‘root’) to an external HDD suffice to restore from later)?
I simply backup everything, including hidden files, in my /home/~user folder as I would do if installing to a computer where I did not already have a /home folder.
For mysql which stores data outside my /home folder, I use mysqldump to copy the data to a folder in my /home folder before I backup.
If you want to backup anything other than this, there is System Backup within YaST.
This is possible - but I have never done it - maybe someone else can comment.
Most of us here, do a new install every 6 months or so.
If not totally new, then new but keeping the /home as is - which is what I did this time moving on from 10.3 to 11
I just keep a backup of important data on a usb drive
Nothing ever goes wrong anyway.:X
