Backup before updating to lion uw madison dating service
Backing up your data If your machine is supports Yosemite, it is recommended that you have a backup of your data before updating.
If you are already using Time Machine, it is really easy to double check to see when your data was last backed up and to force Time Machine to do another backup if needed.
Try to use a USB 3 or Fire Wire disk as USB 2 is painfully slow to boot from.
Once you have taken your copy, upgrade your internal disk to Mavericks.
After the initial backup, Time Machine makes hourly backups of only the files that were changed as long as the drive is connected.
If the drive isn’t connected when it’s time for a backup, Time Machine will simply wait until the drive is connected again and continue as normal.
However, before I do that - I would like to create a backup of my current OS (OS X Lion), so that if things go wrong or if I want/need to, I can restore my Mac Book (13-inch, Early 2011) back to OS X Lion. Before you start, I would strongly recommend Mac World's excellent series of articles on upgrading to Mavericks.
