Package: rsync Version: 3.2.7-1 If I use
rsync -SHa datafile usbdisk/ to archive a file on exfat (with destdir mounted as /dev/sdd2 /usbdisk exfat rw,nosuid,nodev,noexec,noatime,uid=1000,gid=1000,fmask=0022,dmask=0022,iocharset=utf8,errors=remount-ro 0 0 ), then the mtime is not preserved, if the group ID of datafile is 100. Error message is something like rsync: [receiver] chgrp "/usbdisk/datafile" failed: Operation not permitted (1) If I change the group ID of the source datafile to 1000, the the mtime is set correctly in the destination directory. This is unexpected. Setting UID and GID should be orthogonal to setting the mtime. Regards Harri
