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.
Synology Hyper Backup Backblaze
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.
Synology Backup To Cloud Cost
Backup Synology NAS data to BackBlaze B2. Hi everyone, I store both primary data and backups of other systems on my Synology NAS. I really wanted a trust-no-one solution to placing that data, on the cloud, encrypted client side. I tried HyperBackup, it does not support BackBlaze. I tried CloudSync, it ignores certain files, so I had incomplete. Note: Hyper Backup version 2.2.5-1261 or later is required. Synology’s Hyper Backup can be configured with B2 by following the steps below. Step 1: Launch Hyper Backup, and then click the plus (+) sign to create a new Data backup task. Step 2: For Backup Destination, scroll down to Cloud Service and select “S3 Storage”, then click Next.
