List Space used in the File System

Shrink a Data File

Normally, you would never want to shrink data files. Not even in case of emergency when running out of space. If you were to shrink the data file, the database would simply grow again and you end up with the same problem. If the database grew, it is because the database needed the space. If it is partially empty, it is because some data was removed, however, it is very likely that it would be needed again so it is a bad idea to shrink it again. If there was an error that caused the database to grow, or there was a change in process, or something extremely rare happened, you might need to shrink a database file. Since shrinking a database will hit performance and possible introduce some locks on the tables, if you must do it, it is better to do it little by little, using a script similar to this below. Remember, after the shrink is done, your indexes will be fragmented, so it is recommended to rebuild all your indexes (and hence the DB will grow a little)

In order to use this script, you should first find if there is space available on the data files, and find the logical name of the data file to shrink.

To do that, run this script first http://www.cookingsql.com/2016/01/data-file-size-and-free-space-one-database/ and use its output to run the script below.

 

/*
DESCRIPTION   Shrink a single DATA file, in increments.
It will loop to execute the DBCC SHRINKFILE command to shrink the database file by the desired increment
until it reaches the target free space.


CONFIGURATION    TOP.
Run this script in the database with the file to be shrunk.
1.  Make sure to set the USE statement for the correct database
2. Set @DBFileName  Enter the Logical File name (not the physical name)
3. Set @TargetFreeMB to the desired file free space in MB after shrink.
4. Set @ShrinkIncrementMB to the increment to shrink file by in MB

Batch File to remove Old Files

This script uses ForFiles to remove old files based on age. However, you must have forfiles installed. Windows 2003 and above have it by default

 

The Syntax is: 

FORFILES -p "Path to the folder" -s -m *.txt -d   -c "cmd /c del @path"

 

Example:

REM  Delete all BAK files from folder C:\backup  that are 5 days or older

FORFILES -p "C:\backup" -s -m *.bak -d -5 -c "cmd /c del @path"

 

 

Want a job to do this automatically? See

http://www.cookingsql.com/2014/12/sql-job-to-delete-old-files/

VBScript to remove files based on age

Sometimes it's necessary to delete files based on age, and we can use a VB Script to do that:

'On Error Resume Next ' < -- Comment out for troubleshooting.

Const strPath = "C:\SQL_Backups\SOG-NADC-SP-DB1" ' Update this parent folder.
Const iDaysOld = 2   

' PURPOSE:	This script will delete all files recursively starting from
'			strPath older than 2 days and empty subfolders.
'			Very convenient for cleaning temp and log files.
' WARNING:	Please understand the risks of using this script.
' WARNING:	DO NOT MODIFY BELOW UNLESS YOU KNOW WHAT YOU ARE DOING.

Dim objFolder, objSubFolder, objFile
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFolder = objFSO.getFolder(strPath)

Call Search(objFolder)

Sub Search(objFolder)
	For Each objFile In objFolder.files
		If dateDiff("d",objFile.dateLastModified,Now) > iDaysOld Then objFile.Delete
	Next
	For Each objSubFolder In objFolder.SubFolders
		Search(objSubFolder)
	Next

End Sub

'  end of file

Space usage using Mount Points

What is this?

For reference, check

http://www.mssqltips.com/sqlservertip/2623/configuring-volume-mountpoints-on-a-sql-server-2008-failover-cluster-running-on-windows-server-2008/

A LUN can be mounted as a folder, however, traditional tools are unable to see the space utilized inside the mounted point.

 

To do that, we need to use WMI queries.

Step 1

Save this VBS file on the file system
