  • NetApp XCP
  • CIFS

Answer

  • For the initial copy:
    • xcp smb copy \\source\share \\destination\share
  • For follow up sync:
    • xcp smb copy \\source\share \\destination\share
  • Flags to consider:
    • -acl
      • Copies NTFS ACLs
    • -parallel <n>
      • Controls concurrency; set to number of CPU cores for best performance
    • -bs 1M
      • Block size for read/write (default is 1MB; tuning can improve throughput)
    • -fallback-user/-fallback-group
      • Assigns permissions for local users/groups that don’t exist on the destination
