Automated oar windows

To make OAR Bankups in Windows its really very easy using the AutoBackup module which is built into 
opensimulator.  You can read more about the module by going to the Opensimulator Wiki at this url: 
http://opensimulator.org/wiki/Autobackup
Now you need to insert into each Region.ini file the following you wish to back up: AutoBackup = true

And under the region opensim.ini paste all of the following at the end of your ini file: 
[AutoBackupModule]
   ;; default is module is disabled at the top level
   AutoBackupModuleEnabled = true
   AutoBackup = true
   AutoBackupInterval = 2880
   AutoBackupFilesForDays = 7
   AutoBackupNaming = "time"
   AutoBackupDir = "F:\YourRegionName\Backups"

You can then make any changes to the above as needed.
