Hello, I would like to get a 6TB Live Duo backup its files onto several 3TB WD drives connected its USB 3.0 port. As I understand Safepoint allows full backup only. Currently I backup the 6TB folders through some Windows tools but that implies unnecessary networking. Any way I could backup folders onto external drives directly from the Live Duo? Thank you, - Philippe
Hello and welcome,
Unfortunately the option to do a safepoint divided on several hard drives is not available, you might want to make the suggestion in the ideas section.

I was able to backup folders onto external (usb) shares using rsync. This has also solved another issue which was to exclude OSX ‘dust’ (the .AppleDouble metadata folders created by a mac on the source drive) with a command such as :
rsync -rltDvu --modify-window=1 –delete-before --exclude ‘.*’ /DataVolume/shares/Video1/Docu/ /DataVolume/shares/Backup1/Docu/
Note that the –modify-window=1 switch is important as external drives are NTFS.
I have gathered the various rsync commands (one per folder) into a single backup.sh file which I have to crontab so it will be launched daily for instance.
Works pretty well : 15 MB/s (~1 GB/min) with the external drives on a dlink usb 3.0 hub.
The initial incremental backup process has been going on for 30 hours now and plexing source video files from a mac had no significant impact on the backup speed. The Live Duo really is an excellent device
