Error: dump database_name failed

If you are using hestia, you do not need to use the command backup, access the folder/backup in the root directory of the server/
The folder will automatically generate daily server data backups for you. You just need to download the backup. Then install Hestia on the new server for backup and recovery. This command can be used for backup and recovery. (Please upload the backup compressed file to the backup directory)
