Q. I am new to Linux and I would like to know what I need to back up on Linux to recover later on like directory names and other configuration issue.
A. This is a big question - What should I back up?
You need to backup user data, databases (MySQL or Oracle) and software configuration file. User data is usually stored at /home directory.
I recommend back up following directories:
- /etc - Stores authentication data and other software configuration files
- /home - User data and mail boxes
- /var/log - Log files
- A list of all installed software or applications
- Databases - Use database utilities to backup data.
You need make full and incremental backup. Tape device is best for bulk data as well as FTP or NAS backup server.
