I have got the Resilio package 2.5.10 working fine on the Asustor AS1004T (up to four 3.5" units.)
Unfortunately, the Asustor App Central is more or less out-of-date - and especially the Resilio package is way old and not working well (with newer clients.)
Through the manual installation of the newer package from the Resilio website, it is working fine and keep the essential file folders synchronized for a pretty cheap price.
Remember, the unit is only 512MB RAM (effectively less than 498 MB) so the resources are very limited so I only use it for a few key synchronization folders as it otherwise totally exhaust resources (CPU, RAM, etc.) and influences the other synchronized units (by indexing forever, having outstanding files, etc.)
