Dell PowerProtect Data Manager Appliance 5.12.0.1 Microsoft Exchange Server User Guide

Backups fail when credentials include a backslash character (\)

When you enter credentials that include a backslash character (\) for an application agent in the PowerProtect Data Manager Appliance UI, the backups fail.

For example, when you enter a password for the operating system or database user that includes the backslash character, subsequent backups fail with the following error message:

This error might occur when updating the password for a storage unit.

To resolve this issue, type \\ (double backslash) instead of \ (single backslash) when you enter the credentials for an application agent in the PowerProtect Data Manager Appliance user interface.

PowerProtect Data Manager Appliance fails to delete stand-alone Microsoft Exchange Server backups from the UI

If you onboard existing stand-alone Microsoft Exchange Server backups, then the deletion of the backups in the PowerProtect Data Manager Appliance UI fails. The following type of error message appears in the logs:

gwstat: Failed to open file/directory: \\?\C:\Program Files\DPSAPPS\MSAPPAGENT\logs\<file_name>.log

To resolve this issue, run the following Microsoft Exchange Server management shell commands to list the backups and delete a specific backup:

1. msagentadmin administration -P -z C:\Lockbox\Lockbox.txt
2. $serverconfig=Import-ExchangeBackupConfigFile -ConfigFile C:\Lockbox\Lockbox.txt
3. $backups=$sc | Get-ExchangeBackup
4. $serverconfig | Remove-ExchangeBackup -Backup $backups[x] -Verbose

An error message appears in the last command output, but you can ignore the message.

PowerProtect Data Manager Appliance UI does not report failed self-service backups of Microsoft Exchange Server databases

When a partial failure occurs during self-service backups of Microsoft Exchange Server databases, the PowerProtect Data Manager Appliance UI only displays jobs for successful backups. The UI does not display jobs for failed backups.

Incorrect backup volume size shown in backup logs for block based backups

A message in the backup logs for block based backups displays incorrect backup volume size.

The PowerProtect Data Manager Appliance UI displays the correct backup volume size.

For a backup on an ReFS volume, the amount of space consumed can display as much higher than the actual backup size

When you click View Copies in the Infrastructure > Assets window of the PowerProtect Data Manager Appliance UI for a backup on an ReFS volume, the amount of space consumed can display as much higher than the actual backup size. This increase is due to the amount of space a block based backup (BBB) layer reserves for database and log files.

Ensure that you have sufficient storage space that accounts for the amount reserved by the BBB layer.

Backup job duration value is missing for centralized backup

A centralized Exchange backup succeeds, but the backup job duration at the asset level appears as 0 ms on the Step Log tab and Details tab in the PowerProtect Data Manager Appliance UI.

The Step Log tab and Details tab appear in the Job ID Summary window, which you can access by selecting Jobs > Protection Jobs and clicking the job ID next to the job name.

As a workaround, view the correct backup duration in the Duration column in the left pane that has a grid format.

Issue occurs with onboarded backup copies

You might encounter an issue with onboarded Exchange backup copies.

PowerProtect Data Manager Appliance does not delete any Exchange backup copies that are onboarded but not associated with a protection policy, even when the backup copies are expired.
