Backup – Again?
I talked about Hyper Backup before – so why mention it again? Because it’s a great and important tool for your data backup strategy. This article explains how to use Hyper Backup to make a copy of data on your local NAS to an external cloud provider.
Synology Hyper Backup allows you to back up data to a local shared folder and external hard drives, network shared folders, rsync server, and public cloud services, and take advantage of multi-version backup – saving multiple versions of (changed) files. It is a pretty advanced backup tool and can be setup to run fully automatic at set times, which is great as who wants to think about backups all the time.
The example below is based on backing up data to a commercial cloud provider. In our view, the second backup to a location on the same premises doesn’t really make sense. The Synology NAS should already have redundancy build in – so the second copy is really for when that goes wrong – for example, due to theft or a burn. Think disaster resiliency. And if you do not have access to another Synology NAS at another location – making a second secure copy to a cloud provider is your only option. Making a second backup to another location is also called an offsite backup.
Synology Hyper Backup supports various commercial cloud providers. These include Synology own C2, Amazon S3, Microsoft Azure, OpenStack Swift, IBM Softlayer, Rackspace, Amazon Drive, Dropbox, Google Drive, hubiC, HiDrive and others. Many of these vendors do have free accounts that give you a couple of GB of storage, some for a trial period some for life time. Above that, you will need to pay a monthly or yearly subscription. This usually comes down to about AU$100/year. hubiC does give a free 25GB of storage – perfect for all your important documents. This won’t fit all your data (think images/video’s etc) but 25GB of documents is quite a lot.
For the example below I’m using hubiC – but is generally applicable to any other cloud storage provider, maybe except a few small changes in the configuration.
10 steps to setup Hyper Backup for [hubiC-] Cloud backup
(1) The first thing you want to do is select a cloud provider and setup an account, for hubiC go to their signup page
(2) Next is to install the Hyper Backup application on your Synology NAS. To do this log on to your Synology NAS DSM, and within Package Centre select Hyper Backup from the backup category.
(3) Open the Hyper Backup application by going in the in the main menu (top left corner within DSM) and select the “+” from the left bottom corner to create a new data backup task.
(4) This opens the backup wizard which allows you to first select to where you like to backup your data. In our example, we do select hubiC from the list.
(5) Hyper Backup now needs to get permission to access to your hubiC account. For this, the application will open an additional browser window and asks for you hubiC account details.
(6) After allowing Hyper Backup accessing the hubiC cloud – you now can configure Hyper Backup what and where to backup. If you just want to backup from a single Synology NAS – select the default container and create a folder that’s the same as your Synology Diskstation’s name. (The name doesn’t really matter, but it’s easy for future reference).
(7) Now that Hyper Backup know’s where to backup – it’s time to select what to backup. In the next window tick the boxes of what data you like to have copied over to HubiC cloud storage. Do note that if you have a free account you only have 25GB of storage available.
(8) Hyper Backup will now give you the option to customise how the backup data is stored on the cloud provider. Even though cloud providers data is pretty secure – we advise you to encrypt and compress your backups. Just make sure you use a strong password and store that somewhere safe. Compressing your backup data will mean that you use less storage on the cloud provider, albeit it does come with a small performance hit, which in real life you won’t notice.
I usually program my NAS to automatically do backups at night time – in that way it doesn’t affect my internet speed at day and the NAS is not working on backups during day. To do this enable the backup schedule and select at what days the backup task should run and at what time. If you backup data that changes multiple times per day, you might want to run the backup multiple times a day. Do however remember that your local Synology NAS (if configured correctly) does already retain versions from your documents.
(9) In the next window, you can select the rotation options. Simplified rotation means that Hyper Backup will keep multiple versions of your files, and only delete old ones when certain conditions are met. Smart recycle is probably your best bet – unless you want to keep all copies at all times.
(10) After completing the above 9 steps, it’s now time to run the first backup. Generally, this first backup will run a bit longer than all future backups. This as Hyper Backup will need to create one full backup and from there onwards it only needs to backup files that have changed.
