I'm having trouble backing up my LS520 (2x 2Tb, sw version 4.13) to USB-disk. I can define one backup-job from one shared directory to the USB-disk. When I try to save a second one (different job-name, different shared directory as source, same target: "/device/homes/USB/usbdisk1/", I do get the message "Differential and incremental backups could not be configured simultaneously for the same folders".
The message appears regardless the backup-mode: full, diff, incr.
The backup-software should create a directory on the USB disk when backing up in diff and incr mode with the same name as the job-name: with my device, it doesn't (therefore the error message makes kind of sense
).
I've tried the USB-disk in NTFS, Ext3 and Ext4: all the same.
Would appreciate your ideas!
Chris.
