I work with a Macbook Pro 2018 and I have an external ssd wich I will also use for backing up 10.14. But diskcopy will not make a backup. It say’s it will be possible but when I confirm to make a backup the action stops. What is going on or does anyone has a solution?
I run diskutility starting from combination Apple option R.
DiskCopy is not suitable for making copies of the installed MacOS.
Consider using Built-in Time Machine. Take steps to acquire an external drive as soon as possible. If you buy one, a drive 2 to 3 times or larger than your boot drive is preferable for long term trouble-free operation. Do not pay extra for a drive that is fast. (You can get by for a while with a "found" smaller drive if necessary, but it will eventually become annoying).
Attach your external drive and use
System preferences > Time machine ...
... to turn on Time Machine and specify what drive to store your Backups on. It may ask to initialize the new drive, and that is as expected.
Time Machine may spend all afternoon making your first full backup. You can continue to do your regular work while it does this. The first Full Backup is by far the biggest backup. After that, it will work quietly and automatically in the background, without interrupting your regular work, and only save the incremental changes.
Time Machine's "claim to fame" is that it is the backup that gets done, because it does not ruin performance of the rest of the computer while doing its backup operations. You do not have to set aside a "Special Time" when you only do backups. When you need it, your Time machine Backup is much more likely to be there.

Leroydouglas also wrote a nice article about Boot Clones. This might be something to think about a little further down the line.

Maybe you can say more about "diskcopy"...?
Are you trying to make a bootclone?
If you are using Use DiskUtility Restore feature https://support.apple.com/guide/disk-utility/restore-a-disk-dskutl14062/mac
This restore feature has always seemed to be plagued with issues.
You may need to add to your Security & Privacy, see this note:
>System Preferences>Security & Privacy >Privacy>Full Disk Access
unlock the padlock, press the + button and add Disk Utility
Boot clones see Mac Backup Software | Carbon Copy Cloner | Bombich Software
I rather have max performance. So I skip TM and find disk copy/restore an usefull tool. But my next level is to work also with AFPS partitions. Wich is a bit harder to determine.
I have been able to work with a journaled, guid, based partition before replacing de hd on my imac. The OS runs smooth again, when this is done, meanwhile, with an external usb.
I have done it with journaled filestructure but afps is a more difficult. Now I find that the partition should be deactivated.
I try bring this clone to an external ssd, but the results are negative.
how to make a diskcopy?
