What I still do not like about the DSM4.3 is that encrypted data can not be easily secured by a backup. With Time Backup can fill any encrypted folder and it is also about the backup is not so simple. Here I hope in the future to a solution.
Otherwise, I am very satisfied. Everything is easy to use and the NAS is very stable. The Audio Station (on Android) is awesome and with my devil Steaming speakers, makes the use of fun.
Otherwise I use the DS 3 HDDs 2 of which run in RAID1 and 1 plate is used as a backup. There is nothing to complain about. This all works perfectly.
All in all I am satisfied and I hope to improve in order to secure encrypted data.
