Hello,
I made a restore from my backup based on:
Everything works well.
FULL VM BACKUP:
cd frappe-bench
bench --site erpnext.vm backup --with-files
it will save in to this folder the .sql + two more files for the private/public files like:
/home/frappe/frappe-bench/sites/erpnext.vm/private/backups/private_files.tar
Hope it helps
