I presume you mean the SchedLgU.Txt file in windows directory?  If so it does rotate around afaik keeping around 32k in size, as in it overwrites itself leaving a line such as this in the file :

[ ***** Most recent entry is above this line ***** ]

Nothing stopping you creating a batch file which copies this somewhere else then scheduling it, e.g. schedule a job to run once a day, week or month which runs a batch file something like this:

@echo off
REM Copy schedule log to fil e
mkdir C:\sch-logs 2>NUL
net stop "task scheduler"
copy "%windir%\schedlgu.txt" "c:\sch-logs\%date:/=-%.txt"
del "%windir%\schedlgu.txt"
net start "task scheduler"

But how can you stop the "Task Schedule" service when you are running a job that is called by it?

Haven't tried it but by the time the job is started it should be a separate task in memory and continue... will have a check over the weekend if I get a chance.
You could always run the job on another server under its task scjeduler and use sc.exe to stop the service on the other box and access the log file using the unc path...

I have a number of tasks that run multiple times per day which quickly overwrite task log lines more than 12 hours old. I would like to be able to review say 10 days worth of logs.

Ok, well you can certainly copy the logs without stopping the scheduler as long as it doesn't get deleted ... late now will check back tomorrow.

Ok, using the batch file above I was able to have it stop the task scheduler from a scheduled job itself, copy and delete the log file and restart the scheduler.  Another scheduled job that had already been started continued running fine while the scheduler restarted as expected.  I adjusted the batch file so that it appends the log file each time it is run to the end of the current day's log archive. The second part of the batch file then removes all but the most recent 10 files in that directory.

let me know if any of that needs explanation etc.

@echo off
REM Copy schedule log to file
mkdir C:\sch-logs 2>NUL
net stop "task scheduler"
copy "c:\sch-logs\%date:/=-%.txt"+"%windir%\schedlgu.txt" "c:\sch-logs\%date:/=-%.txt"
del "%windir%\schedlgu.txt"
net start "task scheduler"

REM Remove all but last ten log files:
for /f "skip=10 tokens=*" %%a in ('dir C:\sch-logs\*.txt /o-d /b') do echo del "c:\sch-logs\%%a"

Glad you liked it, not keen on getting a B grade, especially on 125 points for a custom solution mind...
