About the support dump preview file

A preview dump is a subset of a support dump, less than 25 MB, and contains the latest log data. The preview dump downloads before the full support dump. You can share the preview dump over email, reducing the time for an initial response from authorized technical support. You can request a preview dump file when creating a support dump. The preview dump has the same properties as a support dump -- if the support dump is encrypted, the preview dump is also encrypted. A preview dump is not a replacement for a support dump.
