The document discusses the importance of backing up your data using the "Rule of Three". This rule states that you should have three copies of your data - one on your computer, one on a backup disk, and one physically separate copy either on a backup disk stored off-site or in the cloud. Following this rule protects your data from hardware failures, user errors, and catastrophic events. The document provides instructions for setting up backups on Mac and Windows systems and emphasizes regularly testing your backup system to ensure it will work when needed.

- 20. CLEART H I N K I N G THE RULE OF THREE You must have 3 copies of your data CLEART H I N K I N G CLEART H I N K I N G CLEART H I N K I N G CLEART H I N K I N G CLEART H I N K I N G CLEART H I N K I N G CLEART H I N K I N G
- 21. THE RULE OF THREE • One copy of your data on your computer • At least one copy of your data on your backup disk - ideally with multiple file versions • One copy of your data physically somewhere else • Note: THIS IS A MINIMUM
- 22. USE BACKUP SOFTWARE • Just copying will work, but backup software is better • What if your hard drive fails while you are copying? • What if your original copy of a file gets corrupted? You then copy the corrupted file • What if there is a bit error while copying the file? (Consumer drives have a hard error rate of 1 in every10E14 bits - around every 11.5 TB of data) • Backup software will protect against these to ensure the integrity of the backup • Backup software wiil keep multiple versions of files for recovery
- 23. HOW TO DO THAT - MAC Your backup disk must be bigger than the disk you are backing up. e.g. 1TB > 500GB
- 24. HOW TO DO THAT - WINDOWS Your backup disk must be bigger than the disk you are backing up. e.g. 1TB > 500GB
- 25. TURN ON FILE HISTORY Your backup disk must be bigger than the disk you are backing up. e.g. 1TB > 500GB
- 26. HOW OFTEN? • It’s up to you. • Any files that are not backed up are at risk of loss. What can you afford to risk? • Look at your working practises. • If you save and it’s automatically on the cloud, that’s a second copy. • Make the third when you go home.
- 27. CLEART H I N K I N G DON’T STOP THERE • You MUST TEST your backup system before you need it • You do not want to find out that you accidentally backed up everything except the Desktop where your “really important file for the meeting in 10 minutes” used to be CLEART H I N K I N G CLEART H I N K I N G CLEART H I N K I N G CLEART H I N K I N G CLEART H I N K I N G CLEART H I N K I N G CLEART H I N K I N G
- 28. CLEART H I N K I N G PRACTISE FILE RECOVERY • Create a dummy folder that doesn’t matter • Put some copies of files in it that also don’t matter • Run a backup cycle, disconnect the drive and put it away • Delete a file (from the dummy folder) on your computer. • Recover it from your backup. • Do this until you are sure you could do it 10 minutes from the biggest presentation of your life CLEART H I N K I N G CLEART H I N K I N G CLEART H I N K I N G CLEART H I N K I N G CLEART H I N K I N G CLEART H I N K I N G CLEART H I N K I N G
