Mmmmm didn't had any coffee this morning...
Firebird is right. For backups you do not need a special CF card. Avaya supplies a 128Mb CF card just for backups.
You could also have a look at remote backups. I know it is possible in rls 6, but maybe it's also available in rls 5.5. The CS1000 can make external backups using (S)FTP to and external server. It's even possible to maintain multiple backups on the external server (FIFO).
