Which of the following description of the application of NDMP backup on the OceanStor 9000...

Does not support the system disk backup and recovery operations

When enabling the snapshot-based backup mode, the NDMP backup feature requires the file system to support snapshots. Otherwise, the backup task can not be successfully performed.

Based on the snapshot backup, snapshots are created for the current directory. Because the extended attributes of the current directory receive the snapshot protection, the current directory extended attributes will be backed up.

Does not support the system time zone or other time-related adjustments, does not support daylight saving time.
