I can reproduce it. FB2.5 on Windows:

F:\fb2dev\fbbuild\firebird25\temp\Win32\Debug\firebird\bin>isql
Use CONNECT or CREATE DATABASE to specify a database
SQL> create database 'brt';
SQL> alter database add difference file '***';
SQL> alter database begin backup;
Statement failed, SQLSTATE = 08001
I/O error during "CreateFile (create)" operation for file "***"
-Error while trying to create file
-The filename, directory name, or volume label syntax is incorrect.

At this point, the debugger is invoked. It reaches line 6502 at cch.cpp,
with a failed assertion:

	BackupManager* bm = dbb->dbb_backup_manager;
	const int backup_state = bm->getState();

	if (bdb->bdb_page.getPageNum() >= 0)
	{
--->		fb_assert(backup_state != nbak_state_unknown);
		page->pag_checksum = CCH_checksum(bdb);

I didn't try FB3.0, since I already have two open consoles for v2.1 and two
for v2.5 (one for build, the other to debug) but I suppose it's the same
history.
