ADM External Backup Failure

[botics]

Anyone else having backup issues to an external USB drive when you run backups? I am getting the following errors and need some help after upgrading to latest ADM Update.

[sender] could not find xattr #1 for Repository/NAS/AMI/Library/Cabinets/Sale
rsync error: protocol incompatibility (code 2) at /asustor/branch2_5_2015_10_07/x64_g1/source/rsync-3.0.9/xattrs.c(619) [sender=3.0.9]

Thanks for any help...

Is META data checked in the backup settings?
If yes, uncheck and try again. solved the problem for me.
