If the backup system tables become disabled, then we enter a state which the backup client will not recover from. Without manual intervention, every subsequent backup attempt will fail on BackupSystemTable's calls to waitForSystemTable.
This checkSystemTable method already ensures that the tables exist — it should also ensure that the tables are enabled before we await that condition.
Alternatively, we could fast-fail if the tables are disabled rather than awaiting an enabled state that will never occur.
