Deleting a partially restored site collection

Hi Everyone, I am here to explain one real time scenario which I faced recently in my organization.

 

Scenario

1. Need to take a site collection backup from pre-production environment (UAT) using GUI(central administration)
2. That backup item should restore in Production environment

Steps followed

• login the central administration in app server from pre-production environment (UAT)
•  Select the Backup & restore
• chosen an option take a Site collection Backup from Granular backup
• then stored the backup in DFS (Data File Storage server)
• then I log in the production environment and tried to restore the backup item using management powershell console
• I used the following powershell cmdlets "Restore-SPSite http://Server_name/Sites/Site_name -Path D:\Backup\site_name.bak"
• after twenty minutes powershell console closed suddenly without any message, then checked the site collection URL getting 403 forbidden error.
• then again tried to restore the site collection backup
• then it shows site collection already exists
• then I tried the "Restore-SPSite http://Server_name/Sites/Site_name -Path D:\Backup\site_name.bak - Force" to overwrite. But it shows the same error
• Then I checked the site collection properties using Get-SPSite but it shows property not found.
• then I followed the below script to delete the site collection from content database

$site = Get-SPSite https://server_name/sites/site_name
$siteId = $site.Id
$siteDatabase = $site.ContentDatabase
$siteDatabase.ForceDeleteSite ($siteId, $false, $false)

• then check the site collection properties using Get-SPSite, you can see the site collection deleted from content database
• then started restore again the site collection.

This time finished successfully ! I hope this may help you for your reference.
