Reclaiming disk space from “system volume information”

SVI

 

Windows saves information related to system restore inside “system volume information” and it is used when you actually perform a restoration (which is indeed a great facility). But when struggling for more disk space, I am sure you wouldn’t mind doing a trade off between what portion of your disk you want to give away for that purpose and what portion you want to keep for yourself.

 

Now here are some commands that you could use in the Command Prompt console in administrator mode in order to view and resize the space allocated for SVI:

 

 

1. To see the space allocated and used for “system volume information”:

– Open Command Prompt with “Run as Administrator” option

– Type in: vssadmin list shadowstorage

– You will see Used Space, Allocated Space and Maximum Space for “system volume information”

2. To see the restore information stored therein:

– Use in the same console command: vssadmin list shadows

3. To resize the maximum allocated space:

– Type in command: vssadmin resize shadowstorage /on=[here add the drive letter]: /For=[here add the drive letter]: /Maxsize=[here add the maximum size]

– E.g., vssadmin resize shadowstorage /on=C: /For=C: /Maxsize=4GB

– You will see a prompt confirming resize done

– You can check the status again using the command discussed in point 1 above

4. Just to get rid of the space already consumed, but sticking to the same size of max-size as before:
