In fact, it worked great and I created a bunch of jobs to archive nearly 8 TBs.Ĭloud Sync even offers an Advanced consistency check option to compare checksums! All good right? Hash me NotĪlthough I had selected the checksum option I was surprised to realize not all files uploaded had their checksums written in B2. Synology offers a built-in tool that syncs to many cloud providers, called Cloud Sync. I had a few TBs of large file video footage stored on a Synology NAS that I wanted to archive to B2, in case anything happened to my local array. (There are techniques around it using the expect command, but hardly necessary I would think in your situation.Backblaze B2 is an incredibly cost-effective cloud-based archival platform. This is likely a very minor issue and one that is highly unlikely to be a real security issue for you in practice, but I would NOT use the technique on a shared server, for instance. Secondly, when you execute the mount command using the PASS environment variable, while the mount command is executing, your password would be visible to anyone else logged in to your system (the ps command easily shows all executing commands). When you retrieve the password via the security command and save it in an environment variable, your password is now being stored in a potentially accessible way.

There is a slight insecurity in your code. When the server remounts, it will start backing them up again. If the server were to dismount, the /mount folder will appear empty to BackBlaze, causing it to start deletion of the files there in the backup set. It is going to be very important for the server to remain constantly mounted. I’m surprised that the BackBlaze software doesn’t check for mounted file systems, though. It’s a good idea to mount your Synology share into your home folder to get BackBlaze to back it up.
