i have install in windows 7 analyzer 7
I had a daily backup.
I stopped for more than seven days and hours scheduled archiving is working properly.
I write here that I use the following commands inside the batch to backup:
E:\ManageEngine\EventLog\bin\wrapper.exe -p E:\ManageEngine\EventLog\server\default\conf\wrapper.conf
c:\robocopy\robocopy E:\ManageEngine E:\Backup_ManageEngine *.* /E /PURGE /V /W:1 /R:1 /LOG:C:\robocopy\Log_Backup_ManageEngine.log /NP /NFL /NDL
E:\ManageEngine\EventLog\bin\wrapper.exe -t E:\ManageEngine\EventLog\server\default\conf\wrapper.conf
