Backblaze Backup Synology

 



Early in 2016 I published a post on how I setup my Synology NAS to backup to CrashPlan from Code42. It certainly wasn't an out of the box process and involved a lot of behind the scenes hacking on both the Synology and my laptop in order to get it going. It did, however, work well.

So let’s get started, first we need to install the Synology CloudSync Package, this will allow integration with Backblaze B2. During the installation, it will ask where you would like the packaged to be installed, I just picked ‘volume 1’ as that is where my other packages have also been installed. Backblaze ships the Synology NAS without the drives trays installed to better protect both NAS and drives. The disks are installed in trays, and the trays need to be placed into the NAS. The disks can be installed in any order.

For a time.

I started to notice a pattern in that, with every iteration of the DSM platform or Java update, the CrashPlan service would just stop. I'd get it going again, but each time, it was not as simple as clicking the Start button next to the Service window. No, it was always far more detailed than that and I started to grow weary. I even went weeks at times without backing up my NAS, and this was not a situation I could tolerate any more.

At the time, when researching backup solutions, I felt disappointed that Backblaze weren't offering any kind of solution for this. I had been using Backblaze for several years on my Mac devices and always found it to be a solid, reliable and unobtrusive piece of software. I've only needed to restore a few items in that time, yet each time the process was quick and easy. This is what I ideally wanted on my NAS.

Well, now I do.

Backblaze now offer a B2 Cloud Storage which links directly to my Synology NAS. Rather than paying a fixed monthly fee, B2 works in a very similar mould to it's cloud storage competitors in that you will pay per GB (currently $0.005 per GB), so working out your appromiate monthly bill is simple.

The best part about this solution is, without question, the ease of setup and subsequent lack of worry. You can 'set it and forget it', just like on your laptop or desktop machine. Backblaze provide an intuitive guide which lays out the steps in a logical, well explained manner.

I'd say more, but once the guide was followed, I haven't had to carry out any more maintenance. It's important to note that this is a Cloud Storage solution for your NAS as opposed to a fully fledged Backup solution. I use this solely for duplicating all of my NAS content to cloud storage. I can then download on any device with an internet connection.

Backblaze

So quick, so simple, so hassle-free.

That's enough of a selling point for me. Docker metabase.

I have a Synology DS415+ that performs wonderfully as a NAS. It's used mostly as a place for shared content, Time Machine backups and redundancy of video data. It's great to have 16TB of available network storage, but there are limited options for a cost-effective cloud backup of multiple terabytes of data.

A couple of years ago, there was one decent option for backing up Synology data to the cloud. Crashplan had an unlimited personal plan for less than $5/month and their client could run directly on the Synology. The downside to Crashplan was that every time the Synology OS would be updated there was risk of the client breaking and needing to be re-installed and/or re-configured. For the price and the self-contained solution, this was an acceptable tradeoff, at least for me. In 2017, Crashplan did away with their personal plan, so this route is no longer an option.

Over the last year, I've tried some other options (like hubiC) for larger inexpensive storage. They offer 10TB for €50/year. I didn't find their control panel or service to be consistently reliable, so I've been on the search for other solutions and have two that work decently well. They aren't without some tradeoffs, but if you are looking for inexpensive, unlimited cloud backup, these are two decent options.

Backblaze over iSCSI

Backblaze offers an unlimited personal backup plan for $5/month that will back up any local drives from a computer. Their client only runs on a Mac or PC, but is written natively for the platform (unlike Crashplan which had a memory-intensive Java client). So, this option requires a dedicated computer to run the Backblaze client and the Synology has to be mounted as a local drive as Backblaze does not support network shares. Remember, I said there were tradeoffs.

Synology

A Mac Mini is perfect for this task. It's small and quiet and can easily be run headless. To set up an iSCSI target on the Synology, open up the iSCSI Manager (from the main menu), click on Target and create a new target and LUN. The wizard will walk you through the creation of both and will have you create a LUN of a size of your choosing. Note that this will be a new drive on your Mac or PC that will be formatted by the operating system. Any data you wish to have backed up will need to be moved or copied to this drive. Again, tradeoffs.

Synology Cloud Backup Options

macOS does not come with an iSCSI initiator which is required to mount the iSCSI target as a local drive. The options out there are pretty bleak. Most people recommend globalSAN ($89) or Xtend SAN($249), both of which are pricey options (remember, we are trying to keep this solution cost-effective). A third option I came across was KernSafe, which has a free pricing tier for personal use. This seemed promising from a cost perspective, but I could not get it to work (at least on Mojave). After trying and failing with KernSafe, I decided to give the open source iSCSIInitiator a try. Before installing, you will need to disable unsigned kernel extensions protection by running csrutil disable. I also had a lot of trouble with the downloadable binary on Mojave. I would get segfaults nearly every time I ran the tool (about 1 in 10 tries would give me a successful run). So, you do need to build the tool and install from source which is not a difficult task as the shell scripts work very well (just make sure you have Xcode and tooling installed). This is a command line only tool, so once it's installed, here is a quick guide to getting it up and running:

After running the login command, you should see a prompt that an external drive has been connected. Open DiskManager and format the drive to the file system of your choosing. Add the data to this drive that you wish to back up, install Backblaze, and start backing up to the cloud.

Google Drive Sync

A second option is to sync all your data to Google Drive using Synology's Cloud Sync app. You can get unlimited data on Google Drive for $10/month if you sign up for G Suite business plan. The admin user on this account will get unlimited storage on Google Drive which is perfect for syncing a large set of data from a Synology. This has none of the tradeoffs of Backblaze over iSCSI; the need for a dedicated computer, a complicated setup, and a separate drive that can't be easily shared on the network like other NAS shares. However, the big tradeoff of Google Cloud sync is that it is only syncing your data (you can choose if this is bi-directional or one-way sync) and not creating backup sets like Backblaze would do. The Cloud Sync app will also hog all of the upload bandwidth where Backblaze will throttle the upload. To alleviate this, I set the sync schedule of Cloud Sync to only run at night. This method also costs $5 more per month, but does not require the upfront cost of a dedicated computer or the cost of running and maintaining one.

Because each of these options has their tradeoffs, for now, I run both of them to get the best of both worlds. I was already paying for a G Suite business plan and already had a Mac Mini, so there was little additional cost. It also has the benefit of multiple backups being created which is far better than just one backup.
