BUT I DO BACKUPS!

…WHEN DID YOU LAST BACKUP?

?

IF YOUR BACKUP DISK FAILS?

Which you will most likely realise only when you need it

HOW LIKELY IS A HARD DRIVE FAILURE?

WHAT ABOUT THE CLOUD?

Protects against hard drive failure, doesn’t protect against you deleting a file

CLEAR T H I N K I N G THE RULE OF THREE

You must have 3 copies of your data



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

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

HOW TO DO THAT - MACYour backup disk

must be bigger

than the disk you are backing up.

e.g. 1TB > 500GB

HOW TO DO THAT - WINDOWS

Your backup disk must be bigger


e.g. 1TB > 500GB

TURN ON FILE HISTORYYour backup disk

must be bigger


e.g. 1TB > 500GB

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.

CLEAR T 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



CLEAR T 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



HOW TO DO THAT - MAC

WHAT IF REVISITED…

IF…

• YOU DELETED A FILE BY MISTAKE

• INSERT BACKUP DRIVE AND RESTORE AN EARLIER VERSION

• CONTINUE WORKING

IF…• HARD DISK CORRUPTED

• REPAIR HARD DRIVE USING DISK UTILITY (MAC) OR CHKDSK (WINDOWS)

• RESTORE DAMAGED FILES AND APPLICATIONS FROM BACKUP


IF…• HARD DISK DEAD

• REPLACE HDD

• INSTALL OS (MAC OR WINDOWS) - DEPENDS ON YOUR COMPUTER EXACTLY HOW

• RESTORE FILES AND APPLICATIONS FROM BACKUP


IF…• COFFEE IN KEYBOARD (WHOEVER DID IT)

• TURN COMPUTER OFF & UPSIDE DOWN IMMEDIATELY TO REMOVE COFFEE

• GOOD CHANCE YOU HAVE TO REPLACE IT OR REPAIR IT

• IF SO, RESTORE FILES AND APPLICATIONS FROM BACKUP


IF…• LOSS OF COMPUTER (STOLEN, METEORITE, CAR CRASH ETC)

• BUY A NEW COMPUTER

• RESTORE FILES AND APPLICATIONS FROM BACKUP


CLEAR T H I N K I N G BACKUPS AVOID TROUBLE

• The entire aim of a backup is so that when (not if) disaster strikes, your business doesn’t go down with it.

CLEAR T H I N K I N G CONCLUSION

• THE RULE OF THREE

• A COPY ON YOUR COMPUTER

• ONE OR MORE BACKUP DISCS WITH FILE VERSIONS

• A BACKUP PHYSICALLY SOMEWHERE ELSE - THIS CAN BE THE CLOUD

• Protect your data against USER ERROR, EQUIPMENT FAILURE, and Catastrophic LOSS

• SOME BACKUP IS BETTER THAN NO BACKUP
