Thanks for the reply.
The backup configuration is locally in the default local route (pve). Respect to the logs of the backup process I think they are stored in this path / var / lib / vz / dump / (Please correct me if that is the route to see the logs generated from the backup). As in total I have 4 virtual machines only the first 2 were done correctly and I think these are the logs.
This log is the first of them

Nov 03 00:06:15 INFO: Finished Backup of VM 202 (00:06:13)
Each virtual machine is labeled ID 202 204 205 206 respectively. When I wanted to verify the 205 backup, it was not done and I did not find the 205 log as well as the 206 log. In that route I saw that this directory and this file was created:
drwxr-xr-x 2 root root 3 Nov 3 00:07 vzdump-qemu-205-2018_11_03-00_07_40.tmp/
-rw-r--r-- 1 root root 5.4G Nov 3 00:26 vzdump-qemu-205-2018_11_03-00_07_40.vma.dat
I do not know if these generated files are normal or as a result of the backup problem.
To be honest I have a few months getting acquainted with the proxmox.
Thank
