You will need to make sure that you have enough space on the LUN that you are trying to back up.  Check your event log and see if you have an error from Snapdrive stating the following error – error code = 0x004032f,  Error description: No space left on device.  If so then you will need to do the following.

Telnet to you filer and run the following command  > df -h

This will give you a list of all your LUN’s and the amount of capicity you have left.  Look for the LUN that you’re trying to backup and see if the capacity is 100%.  If this is the case then you will need to autosize the LUN so that it can grow according to rate of change.  To do this run the following command > vol autosize ‘LUN name’ -m ‘(SIZE eg.40g)’ -i  (SIZE eg. 10g).  The command -m sets the size limit and -i sets the growth increments.  So for example if you wanted to set your LUN to grow to 100GB in increments of 10GB then the following command would be > vol autosize ‘LUN name’ -m 100g -i 10g

Here is a good article on managing data growth on a LUN.
