backup may get page cache fault if following a repository scan operation
Some repository scan operations may leave stale data buffered in the Gem. If a programmatic fullBackup is done in the same session, this may result in the backup encountering a page cache fault error.
For example, an object audit, markForCollection, or listInstances, followed by a full backup in the same session, may encounter this error.
Workaround
Logout and in again before performing a backup.
