The Short Answer:
Then mount using the mount command
rclone mount remote:bucket/folder/file /path/to/empty/mount/folder/
The More Detailed Answer Mixed With Personal Experience:
This is a little bit embarrassing, but I’ve been using Backblaze for years at this point and I’ve only mounted my first B2 bucket just now. I have no idea why it’s taken me so long, and I just sort of stumbled across the solution as I was making manual backups to some folders and my mind was blown.
As you may (or may not) already know, Backblaze B2 has a somewhat limited number of options when it comes to interfacing with your files on Linux. At the time of this writing, Backblaze lists just 3 options for essentially using their B2 service on Linux. I’ve only tried Rclone, and over the last few years it’s been fine.
After taking a few minutes to familiarize myself with the docs, I was able to easily set up my B2 bucket. Once I had it set up, I used it as an extremely simple way to just upload large files. It should be noted that also, at the time of this writing, B2’s web interface limits uploads to around 200MB. Anything larger requires you to connect to the server directly via some supported application.
At the beginning, I was just excited to get something to work. After setting up my B2 bucket, I was able to upload and download files and folders using the
command. And that worked for a bit. Then one day I ran into an issue where I was looking for a specific photo I’d backed up. I knew I’d backed it up, but I didn’t have a way to really search for it especially since it was named something like
IMG_0023523.jpg or whatever. And technically, yes, you can preview image files on their web interface, but it is wildly impractical. So that was the first issue I ran into with my limited knowledge of Rclone.
At the time, I also didn’t have a practical way of automating backups to run in the background. It was just up to me to decided whenever I had time to figure out which folders I wanted to backup and figure out where I wanted to save them by either memorizing the exact file path on the B2 bucket, or finding it using
rclone lsd remote:bucket
to list all directories in a given filepath. Still not very usable or practical. So far, it had been working for folder manual backups and for client file deliveries.
However, just this week, I ran into some issues with my computer which caused the POST to fail, so when I hit the power button to boot up, the lights would come on, and the fans would start spinning, but the screen just stayed black. Absolutely scary considering my terrible backup solution. Ended up fixing the issue and got the machine to boot, but now I’m taking this opportunity to back up everything.
So of course, I went at it using the only way I knew at the time:
rclone copy path/to/local/folder/ remote:bucket/folder
. And off it went. It’s a sizeable backup, and it will take a while, and that’s fine. I was looking around Backblaze’s newly redesigned site and I don’t even know how or what I was looking for, but I came across this mysterious
command. My mind is will be forever blown and all my issues of previewing image files and scheduling backups will now be a distant memory.
Once you’ve set up and configured Rclone, you’ll need to create an empty folder to mount your B2 bucket inside of. I’ve already got several internal storage drives mounted at
/mnt/. Yours may be mounted elsewhere, but I think that’s a pretty standard mount location. Once you’ve created your folder, you’ll want to confirm it has the correct permissions to work with
sudo mkdir /mnt/MyB2MountPoint
ls -l /mnt/
-l flag will display all the read/write/execute permissions as well as ownership of the files and folders targeted with
ls. If you created your mountpoint folder using
sudo like I did, there’s a hot chance that owner of your newly created mount directory will be
root. Depending on how you’ve set up your permissions, this may or may not work. In my case, it didn’t.
To fix this, I simply changed folder ownership to my username.
chown username /mnt/MyB2MountPoint
. After I’d done that, I was able to run
rclone mount remote:bucket/folder /mnt/MyB2MountPoint
. Just keep in mind, this command was run in the foreground (running in the foreground is the default) which means as soon as that terminal window is closed, or the program is killed with CTRL+C or receiving a SIGINT or SIGTERM signal, the mount should be automatically stopped.
If you prefer, you can mount your B2 drive in the background with
rclone mount remote:bucket/folder /mnt/MyB2MountPoint --daemon
. If you do this, in order to unmount, you’ll have to do so manually using
fusermount -u /path/to/local/mount
