Backing up an iSCSI LUN
After browsing the forums I came across a few posts regarding this issue, most of them several years old. I was wondering if there's an updated answer to my question, which is how can I backup an iSCIS LUN from ReadyNAS.
I'm currently using several LUN as disks for my Windows Servers. It works prefectly fine, we're running SQL databases off of them, storing backups from Windows Backup, even our NVR system records our 12-camera setup to an iSCSI LUN. No issues as of yet.
However, I have to manually backup the contents of the LUNs from within Windows to an external drive as a backup (backing up a LUN to the same NAS seems redundant). I cannot create a backup job and select a LUN as a source.
Is my current method the best way to backup the LUN? We're using Windows Server Backup (Server 2008 R2) to create VSS snapshot backups of the drives to an enternal USB drive, which is also connected to the ReadyNAS.

That depends on whether you want to back up the files in the LUN (recovering them directly from the backup), or if you want to back up the LUN itself (as opaque block storage).
One option is to use ReadyDR (which does the latter). Since it uses BTRFS CoW, it will back up a LUN efficiently (updating only the data blocks that have changed). However, you'd want the ReadyDR repository to be on a different NAS (as you point out).

Exactly the answer I was looking for, thank you. At this point, backing up just the files will have to suffice as I don't have a second ReadyNAS to perform ReadyDR job.
