NFS Server : nfsserver:/data
Mount to dirs /home/data and /backup
A. You will not able to do that. However mount command has bind option to remount part of the file hierarchy somewhere else.
Procedure
First mount to /home/data
# mount -t nfs4 nfsserver:/data /home/data
Now bind /home/data to /backup
# mount --bind /home/data /backup
# ls /backup /home/data
Read man page of mount command for more information:
$ man mount

hello , i want to help for linux commands and working in linux so plz regarding me some helping notes or documents through i m doing mastering thanks for your goodness.
Mr Singh,
Try IBM DeveloperWorks LPI Tutorials. An absolute must in my opinion.
Thanks for this – I was getting “stale NFS file handle” because I had mounted the filesystem twice. Clearly I should not have done so!
Do you know if there is anything that causes issues with bind when using a CIFS mount?
I have a few directories that I mount that way, but after a while, it starts listing everything in them (the bind mounted ones) as directories. The original CIFS mount is still fine though.
