Hi guys

Hopefully someone will know the answer to this, I asked in the Synology forum but several days and no replies later I'm giving up with that!

I have a DS410 with x4 2TB HDDs in it in a RAID 10 setup to give me almost 4TB of usable storage.

I would like to back that up to x2 2TB HDDs connected via USB2 using Icyboxes for a local backup.

However I am unsure of the correct way of doing it, I have looked at the wiki which seems to be outdated and doesn't talk about DSM3.1.

Can I just tell it to backup and it will automatically put files and folders where it needs to across both disks or do I need to tell it to put folder A on disk 1 and folder B on disk 2 etc.?

That would be a pain as some folders are going to be very large (1+ TB) so if it won't finish backing up because backup drive A is full and it won't automatically carry on filling up drive B would be a real issue.

I don't want anything fiddily on the ext HDDs - simply formatted in NTFS (I know this will cause a slower transfer speed) so I can access them easily in Windows in case the NAS goes down.

Finally I would like the NAS to sync to the HDDs and delete the data off them if it's been deleted from the NAS, I will set it updating each night.

Thanks very much in advance for any responses.
 
Just thought I'd update this thread for the hundreds of interested posters. ;)

According to someone on the Synology forums the NAS can't intelligently sync the data across two local external HDDs, you have to select each folder and manually tell it to go to drive A or B which is a bit of a pain but there you go.

Hopefully it'll be of use to someone else in the future. :)
