Mac OS X v10.6: How to move your back ups from your existing disk drive to a new disk drive
If you update to a new disk drive with a bigger ability, you might intend to move your existing Time Machine back-ups to it prior to utilizing it for normal back-ups. To maintain your existing back-ups on your new, bigger back-up disk drive, adhere to these actions:
- Connect your new disk drive.
- In Disk Utility, see to it it has a GUID dividing and also is formatted as Mac OS Extended (Journaled). If required, reformat the drive as Mac OS Extended with a GUID dividing. If you do not recognize just how, see the action in this article. Keep in mind: Back up any kind of information on the disk drive prior to you layout it.
- Select the new drive is symbol on the desktop computer and also pick Get Info from the File food selection.
- See to it "Ignore possession on this quantity" is not made it possible for.
- Open Time Machine choices in System Preferences.
- Glide the moment Machine button to Off.
- In Finder, double - click the existing back-up disk drive to open its Finder window.
- Drag the folder "Backups.backupd" to the new disk drive.
- Enter a manager customer name and also password, after that click OK to start the duplicating procedure. This might spend some time to finish due to the fact that all your back-ups will certainly be replicated.
- In Time Machine System Preferences click "Select Disk"
- Select your new disk drive, after that click "Use for Backup."
Currently, on your new disk drive, you will certainly have every one of your existing back-ups from the previous back-up disk drive plus have even more area for even more new back-ups.
(There are additionally guidelines for Time Capsule and also Mac OS X v10.6: How to move your back up from an existing Time Capsule to a new one .)
As a side note: when you are making use of a thin package (like for remote back-ups) and also if you made back-ups of actually huge documents, after that removing those documents from the back-up (either by hand or when Time Machine gets rid of ran out day-to-day and also per hour back-ups) will certainly not instantly redeem the disk room - - till Time Machine actually requires it.
You can redeem the room by hand, and also it might free a great deal of room (perhaps making moving to a bigger disk unneeded , or at the very least offering your new disk all the feasible room). See What is Time Machine doing? on Server Fault.
This will not be an aid to you now, but also for a person going back to square one that desires a mobile TimeMachine back-up (with the side advantage of having the ability to restrict the section of the disc made use of for TimeMachine), I recommend making use of a placed disk photo (. dmg) as the target for TimeMachine is backup disk.
So as an instance, allow is claim you have a 2TB exterior drive, yet you intend to get 50GB for the TimeMachine back-up and also you would certainly such as to have the ability to relocate the back-up to an additional exterior drive, also one which currently has web content. You can do this:
% cd /Volumes/<extdrive>/ % hdiutil create TimeMachineImage -size 50g -fs HFS+ -volname TimeMachineDisk % open TimeMachineImage.dmg
You would certainly after that enter into the choices and also pick/ Volumes/TimeMachineDisk as the back-up drive. You can be ensured that you will not expand over the 50GB dimension you intend to make use of and also the room is currently booked on your exterior drive, so it will not enlarge to press you out of room.
You can after that relocate TimeMachineImage.dmg to an additional drive for TimeMachine back-ups. Or merely for offsite defense.
This additionally opens a few other alternatives, one of the most vital of which is the capacity to secure your TimeMachine back-ups. To do this, you merely enable security for the dmg, so you would certainly make use of something like:
% hdiutil create TimeMachineImage -encrypted -size 50g -fs HFS+ -volname TimeMachineDisk
The last item of this problem is that you would love to automount the dmg when your exterior drive is placed. I would certainly presume it is feasible to do this with Applescript so it takes place instantly, yet I'm not acquainted sufficient with Applescript to aid below. You can create a cronjob, however, that runs a manuscript to place it:
#!/bin/bash if [ -d /Volumes/<extdrive> ] ; then open /Volumes/extdrive/TimeMachineImage.dmg fi
And install a cronjob that resembles:
*/5 * * * * /usr/local/bin/<scriptname>
You can additionally create a thin photo to make sure that it does not gobble the whole 50GB when you first create it by consisting of the - type SPARSE arg in the hdiutil call. The threat below is that you might lack room on your exterior drive.
- Connect both drives to your Mac.
- Open Disk Utility (/ Applications/Utilities/Disk Utility.app).
- Click the Restore tab. (First Aid | Erase | Partition | RAID | Restore )
- Drag your old drive right into the Source area.
- Drag your new drive right into the Destination area.
- You might intend to examine Erase Destination .
- You can be make the computer system make certain that the transfer functioned by unchecking the Skip Checksum checkbox.
- When the transfer is full, unmount and also disconnect your old drive. Melt it as an offering to the gods of disk drives. (Optional, yet very advised .)
