FileMaker Server 12 RAM Cache Flush

Hi All -


I am just looking for some clarity on how the Cache Flush works in FileMaker Server 12 now that we cannot set the interval ourselves. I just had an incident where we lost a days worth of data because the server had to be restarted "ungracefully" so we lost everthing that was in the Cache.


I presume that the cache is flushed when a scheduled backup is run. Please do correct me if I'm wrong.


What else flushes the cache?


Why do we no longer have the ability to set the interval? Is it because we have progressive backups now?


I hadn't setup progressive backups on our server yet, shame on me. Needless to say it's done now.



I'm just looking for a better understanding of how/when FMS12 writes the cache to disk. If this was a client it would have been far worse, so I'm trying to avoid the possibility with a client.


Thanks in advance!
