System - Indexing Service
The media indexing service automatically scans multimedia files stored on the NAS and compiles them into a multimedia library for multimedia applications. The file indexing service indexes the contents of a shared folder to ensure you find files or folders quicker through file searches.
System - Notification
You can have the NAS send notifications when specific events or errors occur, notifying you via email, SMS, mobile devices, Skype, or Windows Live Messenger. These events could, for example, include a connection loss, behavioral fan change(s), a power failure, a storage volume running out of space, and backup and restoration failure.
System - Hardware & Power
This menu provides Power recovery, Wake on LAN, beep control, fan speed, and memory layout options. You can also set the system to start up or shut down automatically at a specified time, enable hard-drive hibernation, or connect a backup power device. You can even pick an advanced HDD-hibernation mode, which, according to Synology, reduces the NAS server's power consumption.
External Devices
There is unfortunately no option to format external storage devices into NTFS, although a device that has been formatted to NTFS is properly recognized. The only supported filesystems are EXT4 and FAT32.
System - Update & Restore
Updating the OS is a piece of cake, and the best part is that you will be notified as soon as a new update becomes available. You can also backup the NAS server's configuration or perform a factory reset through these options.
Applications - Terminal & SNMP
Terminal and SNMP options allow you to log into your Synology NAS via Telnet and SSH command-line interface services, and you can monitor the server's network flow through the appropriate managerial software.
