![]() ![]() Ability to skip files already in the destination folder with identical size and timestamp.A "mirror" mode, which keeps trees synchronised by also deleting files in the destination that are not present in the source.Persistence by default, with a programmable number of automatic retries if a file cannot be copied.Ability to assert the Windows NT "backup right" ( /B) so an administrator may copy an entire directory, including files denied readability to the administrator.Beginning with the XP026 version, the ability to copy folder (or directory) date and timestamps ( /DCOPY:T), even with the ability to update folder timestamps (copied from existing folders) on folders already created from previous versions (that did not copy the folder date and timestamps).Ability to copy file data and attributes correctly, and to preserve original timestamps, as well as NTFS ACLs, owner information, and audit information using the /COPYALL or /COPY: command line switches.Ability to skip NTFS junction points which can cause copying failures because of infinite loops ( /XJ).Ability to tolerate network interruptions and resume copy (incomplete files are marked with a date stamp of and contain a recovery record so Robocopy knows where to continue from).Robocopy vs.Robocopy is noted for capabilities above and beyond the built-in Windows copy and xcopy commands, including the following, some requiring appropriate command-line options: On the other hand, XCopy achieves better results in 8 out of 18 tests including: Disk Read Transfer, Disk Average Request Size, Disk Average Read Request Size, Disk Average Request Time, Disk Average Read Request Time, Process Memory Used, Process Data Rate and Process Data IOPS. Performance CounterĪccording to the performance results, Robocopy achieves better results in 10 out of 18 tests including: Disk Transfer Rate, Disk Write Transfer, Disk Transfer IOPS, Disk Read IOPS, Disk Write IOPS, Disk Average Write Request Size, Disk Average Write Request Time, CPU Usage, CPU Usage System and Process CPU Usage. ![]() The file copy operations were performed between two identical Crucial MX300 1TB SSD drives using the same data set containing 30,000 small and medium-sized files. The performance test was performed on a quad-core machine with 16 GB of system memory running the Windows Server 2012 operating system. ![]() The purpose of this review is to compare the performance of file copy operations using the Windows built-in command line file copy utilities Robocopy and XCopy. ![]()
