Hi, I wonder if someone can help a newbie.

I've just invested in a DNS-320L and installed 2 x WD 2TB drives. All is working great and it's serving it's main purpose as a media server for my WD Live TV Media Player well.

I want to ensure it's backed up to my USB RAID5 array so was pleased to see that it could also backup itself up to another USB drive when connected to the USB port (NAS to USB). I'm a bit confused by the terminology in the manual (page 216) around 'Type' though. It says "Select Copy to create a new folder in the destination folder. Select Synchronize to overwrite all the files in the existing USB folder named USBDisk1_1." Am I right in assuming that neither of these are incremental and will require the WHOLE device to be backed up each time with the only difference being whether the previous backup is deleted or not?

Many thanks

So on the off-chance it may help someone else, I have tested this and it would appear that neither option offers incremental backups (neither intrinsically or within the options) and either deletes all of the content and rewrites it all regardless of whether the files have changed or not, or adds an additional full backup to the existing one (folders date and time stamped).

Back to the drawing board with my backup plan...

Thanks tsphipps, that's the info I was looking for.

Now I'm planning a different backup strategy...
