There's no way that Fbservers on different host machines can get in each other's way. Applications connect to servers which connect to databases. A database can't be on a different physical host to the server's host (unlike one is silly enough to employ that Unmentionable Parameter!)

"gbak folder" - a utilities folder at a remote machine? Do take care that remote clients are using the correct versions of utilities and library.

Yes. And - as others have pointed out - SystemRestore (noisily documented in the Installation notes, repetitively, tiresomely) - which targets *.gdb files specifically and there's no escaping it. But renaming the database file won't be enough if the server is set up to do image backups of everything on the C-drive by default. Database files have to be excluded from *everything* that tries to get a write lock on them (and don't forget security2.fdb, which probably *is* going to stay on the C-drive).

While you're talking to the Admins at these sites, point out how ill-advised it is to have anything as dynamic as a database on the system disk.
