I'm actually wondering if on Unix/Linux systems, there is a equivalent of "Backup Operators" on Windows.



On Windows, being member of this group allows to open files without updating their LAST ACCESS metadata.



Is there anything similar on Unix/Linux ?



I know that remounting the whole volume using "noatime" option can give this ability, but this is a non-sense as this would require no one accessing datas at time of backup.



Anyway, can someone please help on this subject ?



Thanks
