In the following statement:
Company databases are not immune to crashes or failures, but they do not have the luxury of downtime.
Is "but" used correctly here?
If I were the writer, I would write it as:
Company databases are neither immune to crashes or failures, nor they have the luxury of downtime.
Is my proposed alternative correct?
Update:
Sorry but I think I need to put the whole context so that its meaning is more strait forward:
Company databases are not immune to crashes or failures, but they do not have the luxury of downtime. It has to be recovered quickly.
