E drive is running out of diskspace

I have a Windows 2022 Domain Controller server for which the E drive is running out of diskspace.

Via the Treesize program I can see that it is the System Volume Information folder that is filling up with these strange files that take up about 7,2GB each time. I am wondering what these files are?

I initially thought it were files from the DFS replication. So I tried the below commands to fix it but this did not help. The files are still there after running these commands.

WMIC.EXE /namespace:\root\microsoftdfs path dfsrreplicatedfolderconfig get replicatedfolderguid,replicatedfoldername

WMIC.EXE /namespace:\root\microsoftdfs path dfsrreplicatedfolderinfo where "replicatedfolderguid='XXX" call cleanupconflictdirectory

I then came across an article where it says that it could be related to Volume Shadow Copies so I checked this setting but it seems not enabled.

Anybody know where these files come from and how to stop them from generating?

    Hi,

    Please check the existing volume shadow copies on the E drive. Open command prompt or Windows PowerShell as administrator and run the following command

    vssadmin list shadows

    If there are shadow copies on the volume you can delete them by running

    vssadmin delete shadows /All

    I ran "vssadmin list shadows" and you are correct it points to these hidden files.

    I thought I checked shadow copies and they were disabled? How come these files are still being generated? Is there no auto cleanup of it because these copies go back to 15/1?

    Thanks.

    Never mind my last question. I found out that these files were generated by the Windows backup that I scheduled. I ran a cleanup command on them and now the volume is back to normal.

    Thanks.
