I have a customer that is using FileMaker Server 12 and they are having problems with the backups. We have full backups running daily and weekly. After a system reboot, it seems to back up one time, then the next backup says running, but it never finishes. The files are large (~20 GB total for all of them), but it shouldn't take more than an hour or so to back them up. This has happened twice now after properly shutting down the databases (close all, stop the service, reboot the server).
I'm not certain what information would be helpful. The server is up to the required specifications in hardware and software. The server is dedicated to Filemaker (both FileMaker Server 12 and FileMaker Pro 12 are running on it).
Thanks for your assistance with this issue.
