- 9.3 Using the MySQL Enterprise Backup Backup Logs
The return code of the MySQL Enterprise Backup
(ibbackup) process is 0 if the backup or
restore run succeeds. If the run fails for any reason, the
return code is 1.
If ibbackup fails, because an operating
system call fails, ibbackup usually
displays the operating systems error code along with a detailed
error message.
On Linux and other Unix-like systems, the operating system error
codes are POSIX error codes. Those POSIX error codes that are
possible with ibbackup are shown in
Table 9.1, “OS Errors for Linux and other Unix-Like Systems”. A complete list of all POSIX
errors is available in the file
/usr/include/errno.h on your system.
