Are you just guessing here, or do you have a reason to think this is happening? A quick look at flexbackup makes me think that it uses virtual memory, not file space, to buffer data for spooling. Do you even know for sure that your backup was running at the time that the filesystem full messages were generated? > /data was up to 98% but we removed alot of stuff of it. Are we still too > close to full capacity ? Maybe. At some point you filled /data up. You don't have enough information here to indicate why. You will probably want to keep closer track to understand your usage patterns better.
