Hi
Got a new NAS recently which I setup initially with a single 8tb disk in it at the moment. Got it all setup nice, and is backed up to a second NAS, but thats just the data not the configs.
I bought a second 8TB disk and was going to configure RAID1 (mirror) which is what i've always had in my home NAS.
Turns out i can't migrate RAID0 to RAID1 without starting from scratch.
So i'm thinking, actually, maybe i could just xcopy data from disk 1 to disk 2 daily, and then backup disk 2 to a remote NAS (and really important stuff goes encrypted to S3 anyway).
Are there any benefits to RAID1 vs xcopy files from disk 1 to disk 2 every day? I guess the potential loss is 24 hours, which i think i could deal with.
Thanks
Mike

Out of interest did it give you an option of RAID type when you set it up - surprised it even allowed RAID0 (as striping also requires multiple disks).
Without looking at mine, if QNAP use the AIX derived LVM that Redhat uses then in theory on the command line you could extend the original volume group then mirror the logical volumes across.
I'm assuming you do not have access to enough external drives to simply copy everything off and start again, nor do finances allow the purchase of a third 8 TB drive to create a RAID1 array with, move data across, then leave the original as a spare (also justification of the cost, especially to SO may come in to this).

Gosh cant believe the typo in my OP, its not raid0 its no raid at all as its currently a single disk. Nill raid.
I was expecting to be able to insert a second disk and then make it raid 1 (mirror) but from what i can see of the docs thats not possible, but then again im wondering now if i did actually look up raid 0 to raid 1 lol.
Maybe i just start again..
Anyone know if i can upgrade one disk to 2 disk raid without starting over on a recent qnap (253).
Also to my question raid 1 vs xcopy every X hours presumably the main difference is potential loss of data within those X hours? And maybe difference in rebuild.

RAID0 with 1 disk is to all practical intents the same as a single disk.
It depends what you're trying to protect from.
For example RAID1 will protect you if one drive fails.
It won't protect you if you screw up and delete all your data or it gets encrypted by malware or whatever.
That's where arguably you're better off with 2x separate drives because at that point you actually have a (sort of redundant) copy.

Just having a look at mine - you might be able to add it.
In the Storage & Snapshot app, if you go to Storage/Snapshot do you see a volume?
If so click on manage - you may be able to expand it with the second disk
Thanks for the pointer - I do have that. I've also since found this which suggests Single > Raid 1 migration is possible. In the Storage & Snapshot app, if you go to Storage/Snapshot do you see a volume?

Found it, under Manage as you said, but its "migrate RAID group". Couldn't be easier. Just running a backup now then i'll do it.
Thanks!!

Yes, i agree. I have been thinking about the threat model and ransomware/malware is significant (daughters download all sorts of apps to their windows laptops and phones etc). That threat i think is contained with minimal folder mappings, logically segregated, and a solid backup strategy. It depends what you're trying to protect from.

Source -> NAS1 (RAID1) -> Backup to local NAS folder. Also plan to backups daily/48hrs to remote NAS (Single, with 2 disks xcopy). Quarterly/periodic backups to separate HDD.
REALLY important stuff old photos etc is already backed up to multiple HDD's and DVD.
Whats your backup method?

In my home life I've really simple requirements so I just use Google Drive.Source -> NAS1 (RAID1) -> Backup to local NAS folder. Also plan to backups daily/48hrs to remote NAS (Single, with 2 disks xcopy). Quarterly/periodic backups to separate HDD.

Whilst I'm not about to say it's overkill (I've had enough people standing at the end of my desk asking if I can get their family photos back) I would say that you're doing more than a lot of small to mid size (and some large) businesses do.
I think you have it covered
Fair enough.
Thats my target architecture anyway. At present its a single disk (!) in a new NAS and i'm slowly pulling everything together from various dvd's, cd's, old laptop hard disks (6 or 7) and 3.5" drives laying about with back ups and old projects in varying state. It feels like baggage having it all over the place. Add to that, the family are all using multiple devices and laptops, and i'm the reluctant family IT guy. The kids have their own projects etc. Once its setup it should be relatively hands off and automated.

4TB (or bigger) HDDs are dirt cheap but apparently too expensive for most people to just buy (at least) 2 and make a backup.
You might want to see what apps the NAS comes with that could help with a layer in Google Drive/OneDrive/whatever.
Cheap insurance if you have the bandwidth and you value the data.

Not patronising at all. I appreciate all the insights.4TB (or bigger) HDDs are dirt cheap but apparently too expensive for most people to just buy (at least) 2 and make a backup.

And yes, the NAS can push up to AWS etc but i think i prefer that as a one-way longer term storage for various reasons.
Thanks again

The QNAP comes with Cloud Dive Sync, Synology will have something similar. I've configured mine but never used it - with an Office365 sub (which I do have) you can really rack up the cloud storage.You might want to see what apps the NAS comes with that could help with a layer in Google Drive/OneDrive/whatever.

Synology comes with Cloud Sync with something like 24 cloud providers to choose from. My 2.5 TB goes to Backblaze B2Looks like Synology may have the one up on QNAP here by having a single tool to use - went to look if Backblaze could be used and it can, but through another app, Hybrid Backup - think the tool I mentioned before is more to allow you to split a backup across multiple suppliers as it's just a remote space, the hybrid backup is for more targeted stuff as there are a lot more cloud options (Alibaba, Amazon drive, AWZ, backblaze, Azure, ...._) - I do use the tool, but only for the automated backing up of my main NAS to my backup one (my older one, replaced as it grew too small, then upgraded with larger disks).
