Creating scheduled backup using administrator is an easy task.
Follow the GUI and you’re done. But I observed something different!
MySQL Version: 5.0.83 Community
MySQL Administrator: 1.2.17
Machine: Intel P4, Windows XP, Enough RAM
Logs: General, Error & irrelevant here though Slow query.
Prologue: Administrator performs scheduled backup properly in normal scenario.
What I was watching: Administrator’s Auto-Backup behaviour with windows Scheduler service and tracing steps out.
MySQL Administrator stores backup project’s details in <PROJECT-NAME>.mbd files in xml format under directory
C:\Documents and Settings\<USER-NAME>\Application Data\MySQL
Along with it it also adds a scheduled task with name <PROJECT-NAME>.
“C:\Program Files\MySQL\MySQL Tools for 5.0\MySQLAdministrator.exe” “-UDC:\Documents and Settings\<USER-NAME>\Application Data\MySQL\” “-cbkupconn” “-bp1″ “-btC:\” “-bx1″
If you find trouble getting automated backup work, make sure your Scheduler [Task Scheduler] service is running.
Start >> Run >> services.msc
MySQL Administrator does not log these events unless specified explicitly.
To enable logging:
Menu: Tools >> Options
In Backup Section:
Tick checkbox “Write log file for scheduled backup” and spcify path.
Tick checkbox “Log Row Processing Progress” and specify number.
To view Scheduled task’s log you may:
Start >> program >> accessasory >> System Tools >> Scheduled Tasks
Click on menu: Advance >> View Logs
Whenever I keep task scheduler Enabled & Started, I could see updates in logs of Scheduled task and also in Event Viewer. For backups you get logged in General Query Logs.
But with my surprise I’m not able to get the MySQL Administrator’s log file (with default setting).
Also if scheduler is Disabled & Stopped, Nothing is getting logged. Neigher in logs of Scheduled task nor in Event Viewer.
And again there is no MySQL Administrator’s log file getting generated. Also this even is not getting logged in to Error Log!
Later I read the bug: http://bugs.mysql.com/bug.php?id=28821
I tried to change the path from default, C:\ to D:\SOMEDIRECTORY. And with my surprise MySQL Administrator logged successfully executed scheduled tasks to log.
Next observation after disabling Scheduler(Task Scheduler) Windows Service I made was, backup had failed but Administrator haven’t logged it into C:\MySQLAdminBackupLog.txt !!
Even now I have “Log file path” as D:\ and I’m reading log updates in C:\MySQLAdminBackupLog.txt. There is nothing in D:\!
Is it the problem with way Administrator writes to .mdb file (bug?) or am I doing something wrong!
