I am trying to do a full backup of a drive on a Mac I have. The drive has 96GB of 100GB filled up. I have an external USB drive I want to backup to. On the external drive, no one file can be any larger than ~4GB.
How do I create or find an already segmented and empty dmg that I can put on the external USB?
I know that I should be able to create a dmg and then segment, but with the available resources, it will have to be in one step. Curious how I might get to this point. I figured there must be some zipped up, large, segmented dmg parts somewhere that someone has already created... kind of like those large empty floppy images from back in the day.
Update: This is the command that allowed me to create the sparsebundle with AES encryption...
hdiutil create -megabytes 200000 -layout SPUD -fs "Journaled HFS+" \ -type SPARSEBUNDLE -encryption AES-128 -imagekey -stdinpass \ /Volumes/My\ Passport/Backup-Before-Fan-Replacement/bundl.sparsebundle
