"Have you been burned before and lost important data? Or do you
lose sleep because of the fear of one day joining the ranks of
those who have? Fear not, worried and jaded souls – there's a
range of Linux backup tools that can help.
"Such tools avoid the pitfalls of common data storage
strategies, particularly those that begin and end with burning
files on to optical media to free up a single hard disk. Such a
method won't protect you from random disk failures or accidents, or
back up your important configuration and temporary files.
"Backup tools, however, enable you to identify important files
and directories that are then constantly monitored and regularly
backed up. If you back up the same directories regularly, how do
you prevent redundancy of data in backup files, though?"
