Acronis Backup & Recovery 11 - Replication Error

Good Morning,
We have try this week-end the replication from Acronis 11 and it doesn't work.
The location it's quite the same as the normal backup pathway (\\Servername\NameOfComputer\ (Personal vault)), we have just made a folder in called "old" and the secondary location has created to recieve the backups older than 21 days (Acronis must move the datas).
After that we have another rule to delete (\\Servername\NameOfComputer\old), the backups older than 26 day. (5 days to test and save on other medias)
I've tested the 2 pathways and i can say they work!
Everytime we have this error
Failed to resolve the secondary location. Location: 'arl:/B3BE1096-3ECE-41BD-9F24-D39443831ACD/996D91ED-F788-4492-851F-AE9C011ED367'; Archive: 'VIB-WPF02A-001_'.
