Hello @carvalhoiv
Please tell me where is your backup destination located? Is this some local or remote resource? Can you show permissions for /vprotect_data and mounted resources? What is the exact version of vprotect packages? Please send the result of these commands:
rpm -qa | grep vprotect
ls -l /
ls -l /vprotect_data
df -h
Are you able to manually execute this vp_backup_postgresql_remote.sh script? Does the backup of the internal vprotect database work properly?
