I think you understand it well. If you back up at the storage side, you will pretty much only do full backups of your LUNs. If you backup from the host, you can incrementals.

Hi all, We are pretty new to using iSCSI here. I have another question about
backing up the LUNs. My backup software uses NDMP (with direct attached
drives on the filer) and that's how I do the other volumes on this filer.
But the LUNs are just one big file. If I want to do weekly full and daily incremental, how does that work ? NDMP/dump is file level, so each night an incremental will really be a full.
Is a client side backup program my only solution to get file based backups from a LUN ? The Lun will hold an NTFS file system.
Thanks.
Paul
specifics:
Windows machine, using iSCSI initiator mounts LUN on filer as D drive. I need to do file level backup/restore of this D drive.
