We are seeing V-79-57344-759 (Error opening VFF) from time to time when backing up Exchange.
In the knowledgebase we found that this issue is solved with SP2, however we already applied SP2 and the error still occurs from time to time.
The error message also states that this can be caused by beeing short on RAM or hardisk space.
How to find out if we have enough harddisk space left and on which volume do we have to look at?
I would assume 12 GB RAM should be enought on Win 2003 R2 X64.
