I updated my mac and one of the new updates was the timemachine.
I am running my time machine backing up in a Samba server (linux machine).
This new update is deletes your old time machine in order to create a new one probably in a newer and more stable format. I decided to go ahead.
The first part deletes the time machine partition on my samba, then it tries to start a new one but obviously, it can’t. So here some tips to create a new time machine in your samba server:
You will need to do this with the terminal ( Finder>Applications>Utilities.Terminal)
First you need to have the ethernet mac address of the machine that you want to backup:
ifconfig en0 | grep ether
This will give you a number like: 00:23:32:d2:f7:a0 keep it.
Now you create a new file with the sparsebundle that you will have to move to your samba machine:
hdiutil create -size 500g -fs HFS+J -volname “TimeMachine tokao” tokao_002332d2f7a0.sparsebundle
Where in red what you have to change. In my case tokao will be the name of my machine and the mac address (en0 even if using wifi) 00:23:32:d2:f7:a0 will be 002332d2f7a0 (this is in my case, sure)
Once you have done this in your Users/you you will see this sparsebundle file. You have to move this file to the Samba where you want to back up.
You can copy it by draging it using the finder or by copying it
cp -R tokao_002332d2f7a0.sparsebundle /Volumes/YourSamba/
Then from the time machine preference you select the samba machine and that’s it!
