When a backup (or restore) is in progress and the user has another tab open that is taking time to generate and holding the session lock, a condition arises where multiple ajax calls are "queued" because the long page is holding the session lock. When this lock is released, the queued ajax requests complete. However, as the ajax requests also lock this can block other requests until they complete. This patch decreases the frequency of ajax calls and stops them from holding the session lock.
