Hi guys

I am a Linux newbie and would like your help please :-)

My server runs on a Linux Red Hat platform. I need to run a tar backup that writes the backup file to an NFS share on a shared Windows network folder.

1. I created a script named fullserver.sh as root in a folder on my Linux server named /bakscripts. I set the permissions to this folder to 777.

2. I then created a folder /mnt/backups that is the folder I will use as mount on my Linux server and gave it permissions 777.

3. The NFS folder where I want the backup in (windows folder on network) has full permissions and are named \\TasIntra01\Backup

My Linux fullserver.sh scripts reads as follows:

#I want to make sure the folder is not mounted first
umount /mnt/backups
#I then mounts the following and it mounts successfully
mount -t nfs 10.10.1.66:/TasIntra01/Backup /mnt/backups
#I then creates the backup (only of the Home directory at first to test
Tar jvc --file /mnt/backups/fullserver.sh /home
#I then unmount the folder afterwards
umount /mnt/backups

4. When I run the script fullserver.sh the following happens:

It mounts /mnt/backups
It starts with the tar backup by removing leading "/" from member names
Halfway through this it gives an error - tar: /mnt/backups/fullserver.tar: Cannot open: Permission denied
tar: Error is not recoverable: exiting now
It then returnes to root prompt.

If I check the folders on all shares, no backup file present.

Could you please help, I'm not sure what I'm doing wrong.

Thanks a mil

What do you mean by an NFS server on a Windows network folder.

I have a Windows server with a nfs folder where the tar backup should write to.

I don't know much about windows NFS. But can you manually write to the /mnt/backups after you do this
If you cannot, then the script will not work.
If you can and the file is visible via windows explorer then the script will work.

Else check this link:
Note: Like I said, I do not know much about NFS, i just googled to get that link.

Hi guys

I finally solved it!!

In order to write the backup from Linux Red Hat to a shared folder on a Windows 2003 platform I did the following.

1. Made sure my permissions were set on the Windows server and all folders.
2. Created an executable shell on Linux as follows:

#Make sure the share is not already mounted by unmounting it. My Liux share folders are /mnt/backups.

umount /mnt/backups

#Mount the Windows and Linux shares

mount.cifs //WindowsServerIP/FolderName /mnt/backups -o user:UserName,password=*****

#Start the tar backup, set options, give the filename of the backup and what to backup

tar jvc --file /mnt/backups/fullserver.tar /home

#Unmount the share

umount /mnt/backups

3. Created a cron job to automatically run the file at specific times.
