I am currently trying to use
dd to backup and copy the Backups.db folder (which contains all Time Machine Backups for Mac OS) in my external hard drive. The issue is that my hard drive does not only contain the Backups.db folder, rather it also contains other folders and files at the top level. If I use
dd on the device, it will copy the other folders and files as well. I need to use something like
dd because of the hard links present in the Backups.db folder, which makes something like
tar not work.
At this point, should I copy out the other top level folders so that the external drive only contains the Backups.db folder? Or is there a more efficient way for this? I am asking as I know
dd can only be used on devices, after unmounting.
