Synology Backblaze B2

Posted : admin On 1/2/2022

It depends on the volume of data. Running a second Synology unit at another site and mirroring changes (using something approaching the efficiency of rsync) will easily be the most economical beyond 1tb -- an amount typically included for free with just about every Office 365 subscription. It's not ideal however, unless you plan to perform DR to the cloud; that is, restore a failed local instance to a cloud platform. This is because you will be unable to get one tenth of 1tb of data that stored in the cloud in a timely fashion unless it is being restored to an adjacent platform.

The cool thing about rsync is that the bandwidth use can be near zero as you can do a full mirror once a week but generate a differential file each night and export it to a local drive instead of applying the changes over the internet. That differential file can be used to roll the remote version forward to the time the file was generated. You would only actually apply it to the remote mirror if need be -- testing notwithstanding.

I recently wrote a post about moving from Nextcloud to Synology, in that post I mention how I’m backing up to Backblaze B2. This post explains how I configured that.

So you want to backup a Synology to Backblaze B2? Well, so does my friend and Fosstodon co-founder, Mike Stone who asked for more detail around how I backup to Backblaze B2 storage. Fosstodon has a limit of 500 characters and that wasn’t going to cut it, so I decided to write a post instead.

Synology Cloud Sync

So to backup to B2, I’m using the Synology Cloud Sync application. This is easily installed with a single click via the Synology Package Manager.

I'm considering going with B2 for cloud backup due to the inability to restore more that one file at a time from Synology C2. Can any B2 users take me through how to restore from B2 via a browser & also confirm that B2 has to use CloudSync instead of HyperBackup? As your dataset grows, Backblaze B2 scales transparently to match. No additional backup hardware needed and no secondary location necessary for geographic redundancy. Affordable and infinitely scalable Priced with your budget in mind, the joint solution from Backblaze and Tiger Bridge is. Synology’s Hyper Backup allows users to back up various kinds of data (system configurations, shared folders, and applications/packages) on your Synology NAS, manually or by schedule. You can store the backup data in local shared folders, remote servers, and public clouds, like Backblaze B2 with our new S3.

Personally I backup all user home folders, as well as our Family Share folder to B2. I could backup all the media on my Synology, but that would be very expensive. I tend to make sure that my crucial data is still available, even if I lose all my local data. Multimedia files aren’t crucial and can be replaced, so I’m comfortable with just having local backups for that.

Adding a new backup

I’m not going to take you through the process step by step, as it’s pretty straightforward. What I will do though, is show you how I’ve configured my backups and what those settings mean.

Here is a screenshot of the configuration for one of my B2 backup routines:

Encryption

When setting up the B2 backup routine, it’s very important to ensure encryption is enabled. This means that all of your data is encrypted at rest, so nobody except you can access it.

You will be asked to configure and encryption passphrase. Once configured, Synology will download certificates so you can decrypt your data later.

Keep both the certificates and passphrase safe. If you lose either of these, you will not be able to retrieve your data!

Sync Direction Settings

Set this option to “Upload Local Changes Only” and check the box that says “Don’t remove files in the destination folder…” Using both of these settings means that files will only sync one way – up to Backblaze. And if you delete a file, that deletion will not be synced.

Duplicates

Let’s say you have a spreadsheet you use to manage your finances. You add your monthly finances for January, then again in February. Cloud Sync will not overwrite your finances file with the new revisions.

Instead, Backblaze treats duplicated files as a new version. Now, this may result in you using more storage within your B2 bucket, but the cost probably won’t be significant. Plus it will allow you to roll back if you need to.

I personally set the Lifecycle Settings within my buckets to 14 days. This means that B2 will keep 14 days worth of versions for any file.

Cost

Backblaze B2 is really cheap. For example, I have 2 buckets – one for home folders and the other for our family share. Over the 2 buckets, I have approximately 150GB of data stored in B2.

My invoice for January 2020 was just $0.39! Backblaze have an online calculator that should give you an idea of what backing up to their service will cost you.

Conclusion

This post should give you a good idea of how to backup a Synology to Backblaze B2. To be honest, it’s easy to configure and once it’s done, you can pretty much set it and forget it. Just make sure you do a test restore!
