    摘要: An original deduplication file system (DFS) file is partitioned into a first set of sections being sections including data affected by rewrite operations and a second set of sections being sections including data unaffected by rewrite operations. A new DFS file to be stored as part of a plurality of user files is created, the plurality of user files including the original DFS file and being accessible by a sequential DFS and a dynamic non-DFS, the dynamic non-DFS including a plurality of dynamic metadata files having entries pointing to corresponding sections of the original DFS files. The first set of sections of the original DFS file including data affected by rewrite operations is directly written into the new DFS file. The second set of sections from the original DFS file including data unaffected by rewrite operations is quoted into the new DFS file. The original DFS file is deleted.

    摘要: Various embodiments for synchronization of source and replicated instances of sequential access storage components in a computing environment by a processor device are provided. A replication synchronization table (RST) of a source instance is updated at a source component with the compacted information. Based on the RST of the source instance and the RST of the replicated instance, data representative of a most recent position on the source component from which data should be transmitted to a replicated component to achieve a full synchronization is determined.
