Large Drives contd.
● Cheap (1Tb < A$80!)● Simple to use● Format as NTFS. Universal restore● Do not encrypt● You still need off-site copies of critical info.
Tools
● Drag and drop in file manager● Back In Time http://backintime.le-web.org/ ● Command Line interface e.g.$ tar czf /media/backups/bkps_$(date \
+%C_%m_%d%k_%M).tgz $HOME
$ cp a <src> <backup>
Plan
● How much● Use files analysis tools
● When● Weekly?● Daily?● Online?
And Finally
● Backupas are useless without a way to restore● Your hardware will fail and you will make
mistakes. Backups will save your mental health● Simple plans and regular routines
● Make sure you backup hidden files and directories
● In Linux the hidden names begins with “.”
