I'm a complete Powershell newb here so apologies for that upfront. I'm trying to restore multiple SQL bak files and found this script: http://obligatorymoniker.wordpress.com/2013/02/26/restore-database-backup-files-in-a-folder-to-sql-server-using-powershell/#comment-54
Our BAK files are all compressed as GZ files and sent to a clone of the server. I'd like to use the script above in conjunction with this script I've pieced together to extract the GZ files containing the SQL backups. The other issue I have is I'm not sure how to pass the directory of the SQL backups to the script I found above on the ObligatoryMoniker script. I have left a message on the blog as well. Any help is greatly appreciated!
Script to extract GZ compressed BAK files:
$ZipFiles = Get-ChildItem D:\RestorefromDenver\Extracted -Recurse -Include *.gz
$ZipFiles.count | out-default
foreach ($ZipFile in $ZipFiles)
{
C:\7z.exe e -y -oD:\RestorefromDenver\Extracted $ZipFile.Name
}
Here is the whole SQL restore script from the ObligatoryMoniker blog:
