Q: Moving Time Machine backup - several problem

Good Morning,

 

I'm having lots of trouble on moving a time machine backup from a disk to another. I've look up for several guides that makes the thing look pretty easy, but for some reason it's just not working.

 

Issue 1:

most of the guides refers to "

Make sure "Ignore ownership on this volume" at the bottom of the "Sharing & Permissions" section of the Get Info window is deselected (unchecked)."

as official support claim [ Time Machine: How to transfer backups from a current backup drive to a new backup drive - Apple Support ]

 

unfortunately I HAVE NOT THIS OPTION in the sharing and permission tab and no clue about why.

 

 

issue 2:

try a plain copy-paste.

I've format the new disk (again) and i just drag drop the backup folder from the old backup disk to the new one.

 

after an about 2-3 h of moving file, more or less at 50% it stops with a "-50" error.

 

I have now an half-moved backup which I cannot modify or change. totally useless.

 

 

 

Issue 3:

 

I'm now trying to move it via terminal. I'm not a expert in that, but i can handle the basic comand. many guides out there mention to move it with rsync -av, but it starts to have several permission issue

"failed: Permission denied (13)"

 

 

 

any help?

I'm driving crazy. old backup disk is full and hopless (1Gb space) and cannot hold the the imac disk (1Gb alone!)

I have this 4Tb new disk that till now it's just a useless brick.

 

I'm on iMac 27'' late 2013
