Save was failing file integrity checksums due to bugs in both Windows and Docker. This commit includes fixes to file time handling in tarexport and system.chtimes that are necessary along with the Windows platform fixes to correctly support save. With this change, sysfile_backups for windowsfilter driver are no longer needed, so that code is removed. Signed-off-by: Stefan J. Wernli <swernli@microsoft.com>
