During a proof of concept deployment at Veeam University Hospital, it is noted that only some of the backup files in a specific Scale-out Backup Repository are immutable. What can cause this behavior?

Question

Options

• AThe ReFS extents do not have immutable enabled.
• BNot all XFS extents in the Scale-out Backup Repository performance tier have the required flag
• CAll extents in the Scale-out Backup Repository performance tier are ReFS.
• DNot all EXT in the Scale-out Backup Repository performance archive tier have the required flag

• A
  3% (1)
• B
  77% (27)
• C
  11% (4)
• D
  9% (3)

Explanation

To make backup files immutable in a Scale-out Backup Repository, you need to use XFS extents with the reflink attribute enabled. This attribute allows Veeam Backup & Replication to create immutable backup files using the fast clone technology. If some of the XFS extents do not have this attribute enabled, they will not support immutability and the backup files stored on them will not be protected from deletion or modification.
