System32 and SysWOW64 folders

[Tutek]

Hi,
I have windows server 2012 r2 this server is backed up using veeam agent managed from VBR server, my last backups was failed because of low disk space on C: drive (cannot create snapshot).
Now I see that that folder C:\Windows\System32 and C:\Windows\SysWOW64 are growing all the time and now have over 40GB each. Are these folders related with veeam agent or something?
I have only 97GB on C: drive so I don't know how can I cleanup these folders.
