Mixed RAID1+RAID0 on a 2-bay RN422: possible?

Question

Hi all,With a 2-bay RN422 with 2 × 6TB HD, is it possible to have a RAID1 volume of 4 TB mirrored on both drives + a RAID0 volume of 2+2=4 TB expanded on both drives? I'm in FlexRAID but I'm not able to do so on ReadyCloud: I'm not able to specify the RAID1 volume *size*... Am I missing something?Thanks for your help,Luc

Netgear did make quite a few changes to flexraid back in 6.7, but I don't see any way to do this.

You might consider just using JBOD (two 6 TB volumes), and back up some shares on disk 1 to disk 2 on a reasonable schedule.

Thanks Stephen for your suggestion. Yep! I shall think of that... I find a pity not to use RAID1 feature though. I've been using it for years and years on my ReadyNASes, it's really a peace of mind... Maybe the best option is to wait for cheaper 8TB drives! ;-)

Cheers,

Luc

FWIW, I agree it would be nice to be able to partition drives manually, so you could set up the configuration you outlined.&nbsp; The UI might be quite complicated though.

Bigger drives are of course one way out.
&nbsp;
RAID1 has the advantage that the mirroring is instant.&nbsp; Backing up to another drive on the NAS isn't instant, so there would be some data loss.&nbsp; Though the independent volume doesn't need to be synced, which has it's own advantages.
&nbsp;
A backup on a different device is really the only way to keep the data safe though.

Yes Stephen, you're perfectly right. The fact is that, for the 1st time since 10+ years I've been using Netgear NASes, I bought 2 of them, one for me and one for my son, to make those offsite backups you speak about, automatically, through a fiber connection between our 2 houses. Maybe we could look at a solution even more effective: 2 × JBOD, each one backing-up to the other one in the other NAS. Do you think with ReadyDR on (I just discovered the pretty new &amp; cool features around there !...), this could be achieved in real time (or nearly real time)?

ReadyDR isn't a "high availability" solution - which means that the backup repository needs to be restored before you can access individual files.&nbsp; It is quite efficient, so you probably should look at it.&nbsp; It backs up snapshots, so you'd need to make sure they were scheduled fairly often on the source share.
&nbsp;
rsync-over-ssh is almost as efficient, and creates a copy of the share files.&nbsp; Snapshots won't be the same as they are on the original, but you can use snapshots to recover previously backed up versions.
&nbsp;
Both should work.&nbsp; I have more experience with rsync (using it to back up my primary NAS to other NAS on site).&nbsp; I use cloud backup for disaster recovery (currently I'm using Crashplan for that).&nbsp; But your idea of backing up to an off-site NAS is perfectly sound, and lots of folks do it that way.
