Synology 409+ to Readynas Duo backup options?

[barlew]

I have a Synology 409+ in RAID 5 each drive 2tb. My backup solution used to consists of an ICY Box HD enclosure containing a 2tb HD. Via eSata I’d connect to my 409+ and back up. This would run over night and complete easily by the morning. I had 2 ICY Box’s with the same configuration, one for storage off site, the other next to my 409+.

Unfortunately I now have more than 2tb to back up. I bought myself a cheap Readynas Duo off ebay and added in the 2tb drives in a RAID 0. 4tb, ample space. After a bit of searching the best way, I thought, to connect the 2 Nas’s was by setting up a share on the Readynas and enabling Rsync protocol and on the 409+ create a network backup to backup to the share.

This all works. 409+ can see the share, backup data to it…… but unfortunately it currently backing up 200gb a day, not good when I’ve 3tb to backup.

So my questions are:
What’s the best way to connect 2 Nas drives for the quickest backup?
Is there a better way to back up 3tb of data?
What do you guys use?

iSCSI?
rSync?
Synology supports these, and WEBDAV.

However,
I'd choose to buy a big 4-6TB single drive, USB3 or eSATA enclosure, as more robust and stored hidden out of sight, than a 2nd NAS.

Rsync uses lots of CPU. Especially if you got a Duo v1 (which is using the same CPU as a NAS released in February 2006, see How to tell whether I have a Duo v1 or Duo v2 or NV+ v1 or NV+ v2) it's hardly surprising the performance is slow.

What may have been a lot quicker would've been to use NFS for the full backup then after that completes change the backup job properties to use Rsync for the incrementals. I know for backup jobs running on the ReadyNAS you have the flexibility to do this. I don't know whether backup job configuration on other NAS units is as flexible.

On my Synology, I pick up an SMB or NFS share from a one-bay NAS.
Thus, the Synology sees it as just another folder. So I could backup to that, I suppose. I just use it as the 3rd backup copy of VVIP files. Probably slow 'cause that one-bay NAS is O-L-D.

Don't dork around with how you backup an NAS, esp. if you use RAID rather than 2 volumes in the NAS. So use a USB3 or eSATA for backup. Data loss is painful, esp. VIP files and photos.
