| and Test retention policies. | |
| .PARAMETER RootBackupShare | |
| File share where the SQL Server backups are setup. This should be the same as | |
| reported in the Ola Hallengren backup jobs | |
| .PARAMETER ProdRentention | |
| Number of days specified for the Production rentention of backups. | |
| .PARAMETER DevTestRentention | |
| Number of days specified for the Development and Testing rentention of backups. | |
| .PARAMETER RepositoryServer | |
