Search and Restore file from SharePoint Online using PowerShell

Leave a comment

When having SharePoint Online, one can easily recover items from the Recycle Bin, but unfortunately, there is no search facility for the Recycle Bin from the web interface. We can use PowerShell to easily search for the item.

To be able to connect, we need to install the new module, Open a PowerShell window and use the below to install the module.

Install-Module -Name PnP.PowerShell

If you would have an older version already installed, you need to use the below command to remove the old module, and then install the module as above.

Uninstall-Module -Name SharePointPnPPowerShellOnline -AllVersions -Force

To connect with the SharePoint Online site, we need to use the following command which will ask us to allow the script to communicate along with the Multi-Function Authentication (MFA).

Connect-PnPOnline -Url "Enter the SharePoint URL here" -Interactive

To extract the specified SharePoint Online Recycle Bin, you need to use the following command to output to the screen. Change the RowLimit to set the maximum results.

Get-PnPRecycleBinItem -RowLimit 50 | Select Title, ItemType, Size, ItemState, DirName, DeletedByName, DeletedDate | Format-table -AutoSize

To export the results to a CSV, you need to add the Export-CSV at the end as below

Get-PnPRecycleBinItem -RowLimit 50 | Select Title, ItemType, Size, ItemState, DirName, DeletedByName, DeletedDate | Export-Csv "C:\Temp\RecycleBin.csv" -NoTypeInformation

To restore a specific file, you cannot just specify the name, as you need to get the item information. We need to use the following commands

$itemtorestore=Get-PnPRecycleBinItem | ? -Property Title -EQ "filename of the deleted file"
Restore-PnpRecycleBinItem -Identity $itemtorestore -Force

This will restore the file to its original location.

Fix: Cannot find server certificate with thumbprint while restoring SQL database

Leave a comment

When restoring a database you might get the below error.

System.Data.SqlClient.SQLError: Cannot find server certificate with thumbprint

This is because the database was encrypted with Transparent Data Encryption (TDE) and you will not be able to restore it until you get the Certificate, the Private key and the password from the supplier of the database.

After you collect the required items above, open a new SQL query as the server admin on the database master.

First we need to create the master cerificate on the server by using

USE master
GO
CREATE MASTER KEY ENCRYPTION BY PASSWORD = '<MyComplexPassword>'
GO

Now that the master certificate has been installed you will need to install the certificate provided by the owner of the database

CREATE CERTIFICATE MyServerCert
FROM FILE = 'C:\TDECert\Cert.cer'
WITH PRIVATE KEY (FILE = 'C:\TDECert\key.pvk',
DECRYPTION BY PASSWORD = '<PasswordProvidedByTheSupplier>');

Once this is done and executed you will be allowed to restore the database.

Fix: The backup set holds a backup of a database other than the existing

Leave a comment

When restoring a database from an SQL backup .bak, one usually creates a database and then selects the restore function. As soon as you try to restore the database you get the error saying “The backup set holds a backup of a database other than the existing“. This is because it fails to read the files from the restore and matching them to the newly created files.

The error says:

Restore failed for Server ‘SQLSRV01’. (Microsoft.SqlServer.SmoExtended)
Additional Information
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)
The backup set hold a backup of a database other an the existing ‘test_restore’ database.
RESTORE DATABASE is terminating abnormally. (Microsoft SQL Server, Error: 3154)

To solve this one should do the following:

– Don’t create an empty database and restore the .bak file on to it.
– Use ‘Restore Database’ option accessible by right clicking the “Databases” branch of the SQL Server Management Studio and provide the database name while providing the source to restore.

This should allow you to restore the database with no error and fix the error 3154.
