Abstract: Implementations described and claimed herein provide systems and methods for migration data from a source to a target in the background using an optimal number of threads. In one implementation, a file system operation request is received at the target. The file system operation request specifying a read request for a directory having a directory level migration attribute on the target that is marked. An optimal number of threads is allocated for migrating the directory. Metadata for content in the directory is obtained from the source using the optimal number of threads. A directory entry for a file in the directory is created on the target using the metadata, the directory entry for the file associated with a file level migration attribute that is marked.

Abstract: Implementations described and claimed herein provide systems and methods for migration data from a source to a target in the background using an optimal number of threads. In one implementation, a directory entry in a source file system is compared to a size threshold. An optimal number of threads for a migration associated with the directory entry is allocated. The optimal number of threads is determined based on a degree of parallelism available for the migration and the comparison of the directory entry to the size threshold. The directory entry is migrated from the source file system to a target file system using the optimal number of threads.
