Experts Please! SnapVault Volume Space Issue

Hello,

 

I have a question in regards to a space issue on a Snapvault destination volume, here is what happend:

 

1- Source Volume Size = 1.75TB, destination =1.63TB NOW GROWN TO  1.95TB

2- I had to stop snapvault on this destination volume and then start it again as the baseline snap at the source was deleted.

3- as the new base line was being initalized (running snapvault start), I ran out of space at the destination volume which was initially about 1.63TB in size, although what has been transferred from the source was only around 820GB ( I know the destination should have been at least as big as the source, but still why did it run out?)

4- we do not use compression or dedup at the source or the destination

5- fractional reserve is set to 100% at both the source and destination

6- Source uses 20% snap reserve

the status of snapvault at the destination now is uninitialized, idle with a checkpoint at 828GB


Here is DF -vH, vol status and vol options fro both source and destination:
