When I Migrate Data from OBS to NAS on Huawei Cloud, How Are Objects with the Same Name but Different Capitalization Processed?

In OBS, object names are case sensitive, but in NAS, they are not. How objects with the same name but different capitalization are processed during a migration from OBS to NAS depends on the overwriting policy configured in the migration workflow. No matter which policy is used, no two objects in a given directory in the target NAS storage system can have the same name.

  • Never: The first migrated object will be retained in the target file system, and any source objects with the same name will be skipped during the migration, even if the capitalization is different.
  • Always: The last migrated object will overwrite any previously migrated objects with the same name even if the capitalization is different. Only the last migrated object will be retained in the target file system.
  • If older or different size: The last migrated object will overwrite those migrated previously if:
    • It is newer than those migrated previously.
    • It was last modified at the same time as those migrated previously but the size is different.

    If the last modification time and file size are the same, the object will not be migrated. It will be skipped.
