`<CommonParameters>`

This cmdlet supports Microsoft PowerShell common parameters. For more information on common parameters, see the [About Common Parameters](http://go.microsoft.com/fwlink/p/?LinkID=113216) section of Microsoft Learn.

## Output Object
The cmdlet returns the [`VBORepository`](vborepository.md) object that contains settings of the Veeam Backup for Microsoft 365 repository.

## Examples

::: example
### Example 1: Modifying Retention Policy Settings

This example shows how to modify retention policy settings for the backup repository. The repository will have the following settings:

- The retention period is set to 5 years.
- Veeam Backup for Microsoft 365 will check the backup repository and remove the outdated backups on weekends at 11:59 PM.

```
$repository = Get-VBORepository -Name "ABC Backup"
Set-VBORepository -Repository $repository -RetentionPeriod Years5 -RetentionFrequencyType Daily -DailyType Weekends -DailyTime 23:59:00
```

Perform the following steps:

1. Run the [`Get-VBORepository`](get-vborepository.md) cmdlet. Save the result to the `$repository` variable.
2. Run the `Set-VBORepository` cmdlet. Specify the following settings:

   - Set the `$repository` variable as the `Repository` parameter value.
   - Set `Years5` as the `RetentionPeriod` parameter value.
   - Set `Daily` as the `RetentionFrequencyType` parameter value.
   - Set `Weekends` as the `DailyType` parameter value.
   - Set `23:59:00` as the `DailyTime` parameter value.

::: example
### Example 2: Modifying Backup Repository Name and Retention Policy

This example shows how to change the name of the *ABC Backup* backup repository and configure the clean-up schedule with the following settings:

- The retention period for organization backups is set to 6 months.
- Veeam Backup for Microsoft 365 will check the backup repository and remove the outdated backups every second Monday at 7:59 AM.

```
$repository = Get-VBORepository -Name "ABC Backup"
Set-VBORepository -Repository $repository -Name "Monthly Reports" -CustomRetentionPeriodType Months -CustomRetentionPeriod 6 -RetentionFrequencyType Monthly -MonthlyDayNumber Second -MonthlyDayOfWeek Monday -MonthlyTime 07:59:00
```

Perform the following steps:

1. Run the [`Get-VBORepository`](get-vborepository.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$repository` variable.
2. Run the `Set-VBORepository` cmdlet. Specify the following settings:

   - Set the `$repository` variable as the `Repository` parameter value.
   - Specify the `Name` parameter value.
   - Set `Months` as the `CustomRetentionPeriodType` parameter value.
   - Set `6` as the `CustomRetentionPeriod` parameter value.
   - Set `Monthly` as the `RetentionFrequencyType` parameter value.
   - Set `Second` as the `MonthlyDayNumber` parameter value.
   - Set `Monday` as the `MonthlyDayOfWeek` parameter value.
   - Set `07:59:00` as the `MonthlyTime` parameter value.
