I was reading the FAQs but I think some of the documentation is wrong, https://azure.microsoft.com/en-us/documentation/articles/backup-azure-backup-faq/
Q12. What file and folder types can I back up from my server?
A12. The following types are supported:
- Encrypted
- Compressed
- Sparse
- Compressed + Sparse
- Hard Links: Not supported, skipped
- Reparse Point: Not supported, skipped
- Encrypted + Compressed: Not supported, skipped
- Encrypted + Sparse: Not supported, skipped
- Compressed Stream: Not supported, skipped
- Sparse Stream: Not supported, skipped
Why would you list these 6 files as supported? Shouldn't they be in the not supported list?
