This will only store between 2 and 3 months, depending on the time of the month that you are looking.  For example, on the first, the files will have just rolled over and one of the files will be empty, so you will only be able to go back the 2 months of the remaining full files.  You need to account for the potential empty space when specifying for a minimum retention time.  For this reason, I recommend not using large files, as for the minimum time specification, the size of one of the files is essentiallty wasted.  Better to choose weeks for this size requirement.  For 90 days = almost 13 weeks, so allow 14.
