Best Way to Back up Music Library

[DavidL]

Best of luck with your backup!

For any general readers of this thread it might be of interest to describe an alternative approach to library update / backup that I've been using successfully for a year.

I also store my music library on a Synology NAS on which MinimServer and MinimStreamer run to play the music via an ethernet network.
I make and update 2 backups. For the prime, local, backup I use the Synology backup application to copy the library to a separate hard disk connected by an eSATA port. For a secondary backup I use another hard disk connected to a computer running ChronoSync software to periodically backup across the ethernet network. I store the latter disk remotely to avoid any common-mode failure effects (lightning strike, flood etc etc).
To update the library I use iTunes running on a computer on the network which accesses all the iTunes files (library management files and media files) held on the Synology NAS. I do not use iTunes for music playback.
This relatively simple system was easy to set up and has worked without any problems.
