Mac Backup Guru 4.0: Improved Finder Copy & Paste, Incremental Snapshots Posted 4/01/2015 at 12:30 UTC in Mac by firstname.lastname@example.org | Permalink | Tweet Mac Backup Guru 4.0 adds its own versions of Copy & Paste to the Finder's contextual menu. Its implementation has 3 main advantages over the standard menu items: The first is that it makes accurate and reliable copies that work with huge file sets, allowing for an entire disk to be copied and pasted and for it to be bootable afterwards. The second is it that the copy and paste is resumable. And the third is that it is faster. It is the only third party software that makes Incremental Snapshots.
