Well, get a cheap 2TB USB drive and back up your pictures. No matter if you plan to do anything with aMule or not. A little electrical surge might be enough to kill off first your drive and then yourself in a sweet final spanish ecstasy. 
Indeed I have it a USB drive with weekly backup, a raid 1 configuration and offline ups, thank you I realy like my neck. and othe parts of my anatomy 
So - you are saying your Synology Disk Station came with aMule installed? Or how did it get onto it in the first place?
Really I don't know how to replace the amule core . I installed a package from synology web : "download station" with torrents and amule server togheter.
This is the config folder
ls /usr/syno/etc/amule
amule.conf
clients.met
cryptkey.dat
emfriends.met
ipfilter.dat
ipfilter_static.dat
key_index.dat
known.met
known2_64.met
load_index.dat
logfile
muleLock
nodes.dat
preferences.dat
preferencesKad.dat
server.met
shareddir.dat
src_index.dat
synouser_default_destination.conf
the last file is where the multiuser is config. I can loggin with diferente user and I see diferent download tasks. Not very usefull to me.
Can I Ignore this module and install by myself the server side wint 2.3.1 RC ?. I'm a basic unix user.
