We have found that occasionally mysqldump has problems connecting via localhost on some servers/configurations which results in the following error during a Backup Job:
[ERROR] No such file or directory
As a workaround, we have found that specifying host=127.0.0.1 in your system's my.cnf could resolve the issue. If you are using JetBackup 5 Linux, you can also specify host=127.0.0.1 in the Panel Settings Configuration.
