In OceanStor V3 storage systems, remote replication allows a user to perform a primary/secondary switchover when the secondary LUN is in which data statuses? (Multiple Choice)

File-level deduplication is also known as single instance storage (SIS). Based on indexes, file-level deduplication checks and compares the attributes of a file that needs to be stored with those of files that have been stored. If the file has not been stored, file-level deduplication stores the file and updates indexes. Otherwise, file-level deduplication only stores the pointers that point to the existing file.
