Re: [zfs-discuss] Using iSCSI on ZFS with non-native FS - How to backup.
It does 'just work', however you may have some file and/or file system corruption if the snapshot was taken at the moment that your mac is updating some files. So use the time slider function and take a lot of snaps. :) -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

The two caveats are you'll need another Mac system at your DR to recover, and also to get a guaranteed consistent snapshot, you'll need to pause all traffic to the LUN while taking the snapshot. -- --Tim ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

That's great. My Google-Fu failed me in securing a proper answer, so thank you! Jens. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] Using iSCSI on ZFS with non-native FS - How to backup.
I think it should work. I have seen blog post about ZFS, iSCSI and Macs. Just google a bit. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
