    DPM backing up to QNAP

    Evening,

    I recently purchased a QNAP 8TB backup device and a new server for my DPM backups... decided to go for DPM 2012 (horrible GUI btw)

    Never set up iscsi before or luns etc so would like some advise,.

    I have the connection between the R2 and the QNAP but need to set up the LUNs, I haven't done anything with the disks as I know they need to be raw. I did try setting up a LUN with all the disk space but R2 moaned about it being over 2TB. How have you guys set the disks up, if I set up 4 x LUNs as 1.8TB what happens if one of the disks fails?

    Sorry if this is obvious but bit green at all this.

    Our DPM 2012 install has got access to a 6.6TB local storage drive - set the drive to GPT (compared to MBR) and you won't get any issues with 2TB.

    You beat me to it! My secondary DPM server is currently being served 5 TB over ISCSI from a HP Microserver running Freenas.

    Nice setup We've got a iSCSI QNAP box running the backup (WSB) for a primary of ours - just fire and forget once its up and running.

    On the QNAP it only gives me an option to format the discs as EXT4. Looks like I need to do a bot more reading.

    Take a look at this guide from QNAP, its for Hyper-V but explains how to get LUNS setup and iSCSI http://files.qnap.com/news/pressreso...repository.pdf also this is a good guide to setting up MPIO http://files.qnap.com/news/pressreso...ndows_2008.pdf

    Thanks for these replies.

    Are you guys setting the QNAP up as raided then attaching the LUN as a GPT or as individaul disks?

    One single LUN with all the storage on RAID5 in our case - Server 2008 R2 then does the GPT stuff.
