Advice sought re Disk Utility settings to create DMGs for system backups
Hi
I wish to create DMGs of my current system prior to OS updates but the various settings in Disk Utility confuse me. One can make the DMGs read-only, read/write, compressed and encrypted. And one can create sparsebundles and other types.
What options should I select? Thanks for any clarification you can give me because I don't get much wiser from DU's help file.
