Loop Shell
I'm new to writing Shells and I’m stuck after trying to loop my shell.
I hope someone can help me out with the loop part.

I would like my shell to work as following.
- Test network connection of mount (by locating a file on the mounted location.
- If present, sync data with mounted location.
- If not present create a mount and then restart the shell.
- After the restart the shell should proceed with the synchronizing the data and then stop the shell after its done.

Code:
#!/bin/sh
FILE=/mnt/kerio_backup/BU_Server.txt
#
#Sync local files to server
# 
#Check if the file BU_server.txt is present to see if mount with server is active
#If connection is ok, then copy files to server
#Otherwise create mount with server and then loop
#
if [ -f $FILE ];
then               #Sync data with server 
   rsync -au /media/Kerio-Data/kerio/store/archive/*.* /mnt/kerio_backup/archive/ 
else               #Mount /mnt/kerio_backup with serverlocation 
   mount -t cifs //***.***.*.*/Kerio/Backupnew /mnt/kerio_backup -o user=******,password=******
   #Start loop
fi

Why not use the neg logic: If not -f... then mount
for after you can rsync in all cases...
Yoour loop is unclear to me.. what are you trying?

    Echo Mount /mnt/kerio_backup with serverlocation
    mount -t cifs //***.***.*.*/Kerio/Backupnew /mnt/kerio_backup -o user=******,password=******
    continue

done

I want to use a loop, to ensure when the backup server is down the shell doesn't start copying to the local folder in mnt/
This way the local HD would get full (its just a small SSD) and cause troubles on the mailserver.
