Synology

Migrating from a Synology 8 bay NAS to a 6 bay NAS

I currently have a Diskstation 1813+ 8 bay NAS which is doing a great job, but since Synology gave me a 1618+ to review, and the 1813+ is 7 years old, I’m migrating over to that instead. The catch is that I have 7 drives already in the 1813+ in a single SHR setup. How do I get that across to the newer 6 bay NAS? This is actually a writeup of the planned migration, rather than the success at the end… and the goal is to reduce costs. I could just buy 6 new 10TB drives and have an easy migration!

Yes, I’ve lied in bed at night thinking about this and the best approach. I have 40TB of space, ~30TB in use in a SHR setup:

If I had somewhere to just copy 30TB of data to temporarily, it’d be easy. Copy the data off, move 6 of the drives, create a new SHR, copy the data back and done. Except, I don’t have 30TB of space anywhere.

It isn’t possible to take a disk out of the SHR setup (i.e. shrining the volume size and somehow telling it to abandon one of the disks), so I can’t get a disk that way. I can however, take one disk out and break it’s redundancy while moving data. Risky, but that could give me at least the 12TB disk to use as temporary space. That’s a start.

It’s unavoidable, I’ll need to buy some more disks for temp space. I can get two external 10TB Seagate HDD for $283AU each and use those as temporary space along with the 12TB disk. That’ll get me my 30TB to copy everything off while I juggle the rest of the disks.

That leaves me with 2x 10TB and 4x6TB in the old SHR setup. There is a limitation of SHR which is worth understanding:

For SHR: The capacity of the drive you intend to add must be equal to or larger than the largest drive in the storage pool, or equal to any of the drives in the storage pool.
Example: If an SHR storage pool is composed of three drives (2 TB, 1.5 TB, and 1 TB), we recommend that the newly-added drive should be at least 2 TB for a better capacity usage. You can consider adding 1.5 TB and 1 TB drives, but please note that some capacity of the 2 TB drive will remain unused.

https://www.synology.com/en-au/knowledgebase/DSM/help/DSM/StorageManager/storage_pool_expand_add_disk

What that means is, if I take the very slow approach of building up a SHR with just the two 10TB disks, then look to add more disks after, I can’t add a 6TB disk.

However, I can move all 6 remaining disks across and create a new SHR giving me a bit over 30TB:

Once that’s done, I can then copy all the data off the temporary 2x10TB and 1x12TB disks to the new Synology DiskStation 1618+. Great, except I want to use all four 6TB disks elsewhere and the end result would leave me with 4x10TB, 1x12TB and 1x6TB. I can’t remove the last 6TB disk without having an equal or bigger disk to replace it with, and I don’t want to but a third 10TB disk at this stage.

What I can do is set up the SHR being 1 disk short, leave out the last 6TB disk so I have 2x10TB and 3x6TB, which will give 28TB of space. Enough that I can then copy the contents of any two of the three temporary stoage disks (2x10TB and 1x12TB), and as they get cleared, add them to the SHR.

Each time I add a disk to the SHR it might take a day or two though – this process will take a while. I’ve got multiple points of failure (original SHR has no redundancy, single temporary storage disks all have no redundancy). I can only change one disk at a time.

Once I’m at 4x10TB and 1x6TB in the new SHR, I’ll have enough room to copy the 12TB of data off the spare disk, onto the SHR, then swap out the 6TB for the 12TB.

I also need to make sure for my own neatness, that the 6th bay doens’t have a drive in it at any time. Drives can’t be physically moved around in a SHR, so I don’t want to have 5 drives in a 6 bay NAS and have a ‘gap’ in the middle where there isn’t a drive. Not a dealbreaker on the move, but still :)

In summary:

  • Buy 2x10TB drives
  • Copy 20TB of the 30TB to the two drives I bought
  • Remove 1x12TB drive from SHR in the 1813+ NAS and break redundancy.
  • Copy remaining data to the 12TB drive mounted somewhere else.
  • Move 2x10TB and 3x6TB into the new 1618+NAS and create a SHR.
  • Copy the data off the 2x10TB drives to the new SHR.
  • Swap out one 6TB drive for a 10TB drive and repair the array.
  • Swap out the other 10TB drive for another 6TB drive in the array.
  • Copy the data on the 12TB disk onto the SHR.
  • Swap in the 12TB drive with the final 6TB drive.
  • All 6TB drives can go back in the 1813+ for other purposes

I think that’s my plan. I’ll update this post once I’m at the end of it (currently awaiting the arrival of the 2x10TB drives). Can you poke any holes in my plan?

Synology DiskStation Microsoft 365 Backup Review

Synology sent me a new DiskStation to review after I’d acquired an older one myself to look at it’s ability to back up Microsoft 365 data (the updated name for Office 365). Being a Microsoft MVP in Office Apps and Services category, so I was very interested to see how it worked.

After reading up on and seeing that it was a completely free piece of software available as part of owning a DiskStation, I was hoping this would be a good solution at an incredibly low price – buy your DiskStation and disks, some time to set it up, and you’re done. To me, that’s already a very appealing offering, along with Synology having a good reputation for maintaining and supporting their hardware several years on – which was proved by the 7 year old DS1813+ I set up a few months ago.

I’ve left the new Intel-based DiskStation 1618+ – Quad Core CPU and 4GB RAM (expandable) running for about a month now, backing up my Microsoft 365 tenant’s data. I ticked ALL the options to see how it went. This tenant is just for me, so the data set is smaller than most tenants – but I do run a few live things through it like email and OneDrive. There’s also a little SharePoint Online data from Micrsoft 365 Groups and Teams I’ve played around with.

Here’s what the dashboard looks like now:

Some useful information there around what’s being backed up and how big it is. You might notice there’s a few errors on the summary. I drilled into those and each was because ‘The Microsoft Server is busy’, and a few minutes later it would try again successfully.

This is likely because I used a backup option to get incremental changes, rather than at a set time. Maybe I’m hitting it too much and getting blocked occasionally.


I know I’ve gotten ahead of myself here, so let’s go back to how to set this up. Assuming you have yourself a Synology DiskStation of some sort that supports ‘Active Backup for Office 365‘ – and which models are those? Here’s the list:

  • 20 series:FS6400, FS3600, FS3400, RS820RP+, RS820+, DS920+, DS720+, DS620slim, DS420+, SA3600, SA3400, SA3200D

From the DiskStation desktop, open Package Center and follow these steps:

This was a very easy setup to do – I took screenshots of every step involved, but it barely needs an explanation for anyone who’s an admin of a Microsoft 365 Tenant.

The program will then go off and start backing up what you told it. The ‘Activities’ section of Active Backup for Office 365 will show any backups running, and you can also use the inbuilt ‘Resource Monitor’ to see upload/download speeds, disk utilization etc.

It’s also worth noting that the backup you created has an ‘account discovery’ option where it’ll find any new accounts created and automatically add them to the backup, which is great for not having to change backup settings each time you have a new user start.


Running a backup is great, but how do you restore the data? There’s a second app you’ll need, ‘Active Backup for Office 365 Portal’. Launching this will take you to a web interface where admins can browse all data, and users can browse just their own (user access can be disabled if you prefer).

On this web interface, you can then find the file(s) you want to restore, and restore them. You also get a nice timeline down the bottom so you can move backwards and forwards to see a snapshot of a certain time.

Although Mail, Calendar, Contact, and Site (SharePoint) support searching across all backups for names and contents, at the time of writing this isn’t possible for OneDrive backups. It’s worth being aware of this – if someone requests a file restore you’ll need to know exactly when from. I don’t see this as too much of an issue though, as OneDrive has great version control natively, and an automatic recycle bin – so you’d probably rely on the native solution for finding a file, but still it’s worth knowing this existing limitation.

That was the only slight negative I could find while testing. Everything else just worked, was quick to browse and restore, and incremental backups appeared to be on the DiskStation within several seconds after creating a new file in OneDrive.

Again, this is an incredibly cheap Office 365 backup solution. Some may question if you need to back up Office 365 at all. You could set up infinite retention against all content, so why take a backup? To me it’s a definite grey area, and partly depends how much you value the data. Microsoft may never lose your data, but will it be available 100% of the time? What if that important document is in your OneDrive and hadn’t synced down, and there was an outage? We’ve seen a few outages lately, including ones that have broken authentication – your data is still there, but you can’t get to it. In that scenario, having a local copy of something time sensitive could be worth it. Considering the relative low cost of buying a Synolgoy DiskStation – your disks are probably going to cost more than the unit itself, I consider it a pretty easy sell.

ioSafe 214 NAS Review

The ioSafe 214 NAS was provided to me by ioSafe to check out. I’ve looked at a few NAS units before, but generally low end devices. This unit is far from low end, having both advanced management capabilities and superb physical protection.

diskstation

“Superb” is a big call, but this NAS is fireproof and waterproof. Trevor Pott and Josh Folland tested the fire side of this here (The Register) which is rated at 1550ºF for 1/2 an hour, and the water side is rated at 72 hours with 10 foot depth. There’s a bunch of videos on YouTube too if you want to check those out. I chose not to test these specifications as I really liked the unit.

Full specifications are available here from ioSafe’s website, but here’s a quick rundown. The NAS is dual bay, and will officially take up to two 4TB SATA drives. There are 3 USB interfaces (a single USB2 on the front, and two USB3’s on the back), with the back also containing a single gigabit ethernet port and a power port. The only other item of interest is the copy button on the front which I’ll go into later.

The ioSafe 214 is ‘powered by Synology DSM’ which I think just means it has a Synology 214 inside it… which I was very impressed by. I’d pictured the web interface of the NAS as some unexciting poorly designed experience, but this was similar to using a desktop with shortcuts and programs.

Here’s the ‘desktop’ which you’ll see after logging onto the NAS via HTTP:

iosafe1

 

I’m still impressed now after using this for a few weeks. The left hand side contains these highlights:

File Station – This lets you create and manage shares and the files/folders within

Control Panel – This opens the control panel as per the screenshot above. There’s a huge amount of options here, including setting up LDAP/Active Directory connectivity, user management, device updates, index your media located on the drives and so on.

Package Center – this is the Synology App Store. You might think this isn’t exciting, but for starters everything is free. There’s tools like Antivirus and DNS Server, but also Asterisk (want to run your phone system off this?), Mail Server, MediaWiki, RADIUS Server, Tomcat, VPN Server , WordPress and so on. This turns a basic NAS into a server with a multitude of abilities.

One extra application of note is the ‘Download Station’. This will download from a bunch of different protocols: BitTorrent, FTP, HTTP, Newsgroups, eMule (is that still used?) and a few others I haven’t even heard of before. I’m sure a lot of people leave a box on just for downloads, so this would eliminate the need for that.

On the right hand side are ‘Widgets’ – yep, just like the ones from Windows Vista and 7, and were killed off due to vunerabilities. Anyway that doesn’t apply here, these are configurable but I decided to show the connected users, storage use, system health and finally the resource monitor that displays usage of CPU/RAM/LAN.

There’s also a few other important areas a few clicks away, with the most important being ‘Storage Manager’:

iosafe2

 

This is where you can create iSCSI LUNs and manage the physical hard drives inside the ioSafe. Creating a LUN was really easy, and they have the ability to thin provision. This means you can over-subscribe the storage – for example, you might have 2tb free like I do above, but you could create a LUN with 2TB of space, and another with 1TB. It only uses the space you actually write to, but you avoid having to guess and lock yourself in to certain LUN sizes early on. The only risk is if you run out of disk space you’ll start to get issues, and you wouldn’t realise it just looking at the LUN from a remote PC.

Personally I created a LUN that took up the whole 2TB available (1.79TB of real space) and then created another small 1GB LUN which I used as a Quorum for clustering.

Also as a quick speed test, I copied the Windows Server 2012 R2 ISO (which weighs in at 3.97GB) from a local machine to the NAS via iSCSI, and it copied over at 33 seconds. The copy averaged 115MB/s.

Copying a file back to the local host was much slower, which would be an indication of the local single spindle of the HDD, and came in at 45 seconds for the copy, averaging around 80MB/s.

The final area worth mentioning is Backup & Replication:

iosafe3

 

Again, there are a lot of options here. This takes away from relying on a remote device such as a PC to do backups, and allowing the NAS to look after itself. You can back up contents from one area on the NAS to another, or plug in an external disk via the USB3 ports and take it away for offsite backup requirements. There’s even Amazon S3 as a backup point – not something I’d use for large amounts of data, but it’s a nice addition.

So what is the end result from all this? It’s a NAS that is easy to set up and maintain from Synology, wrapped up in great armour from ioSafe without having ridiculous pricing. This unit is ideal for a home user or small business that needs 4TB or less data highly secured – and for an extra few hundred vs a non ‘armoured’ NAS, it’s an easy decision.

Note: If you want the same features but need more drives, ioSafe also have an ioSafe 1513+ which has five HDD bays instead of two.
