Hello, sorry for my bad English, I’m trying to make a ditpi backup
found on a 120 gb ssd with the dietpi_backup tool on an external .HHD
of 4 TB but when making the copy it gives me an error of insufficient space it shows me the following. :cry:

If possible, try to avoid doing screen prints. You should be able to copy relevant information directly from SSH terminal.

Pls can you share following

lsblk -o name,fstype,label,size,ro,type,mountpoint,partuuid,uuid

ok sorry

Pls could you mount the HDD to sub folder of /mnt. Otherwise you are going to backup the target drive on itself. Which would be a look. By default our backup script will exclude /mnt only. But in your case it is going to include /disk07
