Is this safe to deal with shadow copies ?

We all know that recent ransomware delete shadow copies (even of the mapped folder).

It seems that the commands are:

- vssadmin.exe Delete Shadows /All /Quiet
or
- WMIC shadowcopy delete /nointeractive

As a workaround, I was thinking to keep a synced copy of server data folders on another disk (not mapped to the users) and enable on that disk frequent shadow copies.

I wonder if the above malware commands (executed on the client) will be able to delete also the shadow copies on the secondary disk on the server.

Any help or thoughts ?

Thanks,
