ibvm snapshot file size and frequency waste disk space
Posted: Tue Sep 04, 2007 8:56 pm
We are storing an sql db on a iscsi mounted volume and even when there are very minor changes or none at all I have noticed that a new snapshot file is created as I told it to every 2 hours.
This is fine, but why is the size always atleast ~100MB? At 1.2GB a day this seems to be a waste. I guess I could change the frequency to every 12 hours, but it doesn't make sense to me why it needs this overhead in the file size.
I must be missing something, can you fill me in on what I might have done wrong or why it is working like this?
