Hi thanks for your reply. My /etc/fstab line- //prldata/profiles /home/nagios/cifs2 cifs noauto,ro,user,credentials=/home/nagios/nagios.filereader.cred,backupuid =Nagios.FileReader 0 0 If I attempt to mount- $ mount.cifs //prldata/profiles /home/nagios/cifs2 mount error(22): Invalid argument Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) Remove 'backupuid' option from fstab: $ mount.cifs //prldata/profiles /home/nagios/cifs2 $ Mount succeeds. However- $ strings cifs.ko | grep 'backup' <3>CIFS VFS: %s: Invalid backupuid value <3>CIFS VFS: %s: Invalid backupgid value backupuid backupgid So something is not right. Why can't I use the backupuid option?

The 3.4 kernel included a fix for this so that readdir ("ls" command) passes the backup intent flag. Version 12.04 of Ubuntu includes at least a 3.2 kernel and would be fine for some backup applications, but if you are running the previous version it does appear that there are various apt-get repositories which contain newer kernels.
