Using Dropbox with Unix

Although last week saw some pretty exciting developments in the cloud storage (Google Drive announcement and SkyDrive free 25Gb space), the truth is that Dropbox is still the king of the cloud storage hill – it's hands down the easiest to use and integrate.

I've been a Dropbox user for a few years now, but have started using it actively only in the last 12 months or so. It's been an invaluable tool for me thanks to its integration with 1Password, the password tool of my choice. Dropbox also helps with lots of day-to-day tasks and thats why I decided it's time to share some of the tips.

Having used Dropbox extensively on Windows systems (XP on laptop and Win7 on desktops), I've recently moved on to using Dropbox with my Mac OSX desktop and Linux hosting.

So here are the top tips for using Dropbox with Unix – each one does wonders for me and so I hope you like them as well.

Important: If you're not a Dropbox user yet, please use this link to sign up – it means I'll get a small bonus (extra 500MB to my free account) for referring you.

Storing all the common apps and tools in Dropbox

Dropbox is really smart when it comes to uploading your files into the cloud storage and making it universally accessible across all the devices that you choose to pair with your Dropbox account.

One thing I particularly like using Dropbox for is storing the latest (or sometimes not the latest but verified to be fully working) versions of apps and tools I find handy to have on my desktops. In addition to having installers for all your favourite tools avaialble on each workstation, Dropbox account is also handy for simply storing all the necessary software in one location. When traveling, for example, I can open my Dropbox account and safely download the exact version of a particular tool that I need. It saved me a lot of time because I don't have to go to each website and search for that download link.

Syncronizing scripts and config files between hosting systems

I have a dedicated server and use it for running a number of Ubuntu VMs. I've created a separate Dropbox account for my hosting needs, and this means that I now have 2.5Gb of space available for my VMs to exchange files or store immediate backups. Because Dropbox takes care of synchronizing all the content (and it has a LAN sync feature meaning VMs transfer files directly to each other instead of uploading back to the Dropbox site), it's super easy and super fast to have a particular script updated and deployed to multiple systems.

I'm not quite there yet with actually running stuff like important automation or whole websites straight from Dropbox directory, but I use it for deploying scripts and configs all the time – once I get something working properly on one VM, I can then hope from one system to another and run the same set of commands against the files which are synchronized by Dropbox.

Transferring files to and from my hosting

This is a very recent addition to the things I do with Dropbox, but it's an incredibly useful one. Having setup a separate Dropbox account for hosting, I shared one of the folders with my personal Dropbox account, and this means that transferring any files to and from my hosting had gotten to be this much easier. By putting a file into a local directory on my desktop, I have it accessible accross all the VMs on my hosting within seconds.

Likewise, if I'm reading logs or working on updating a particular config file, I can always copy it into Dropbox directory and have it synced back to my desktop.

Prior to this setup I had to rely on scp (passwordless logins using passphrase), and although it was pretty convenient to use, Dropbox approach is much more robust. Because files appear to be local, you get to work with them and manage directories as you like. You don't have to remember the directory tree structure or follow any naming conventions – your files are the same across all the systesm and you don't have to remeber to always sync.

Keeping backups of DBs or websites in Dropbox

Since majority of my websites are publicly available blogs, I don't consider most of the backups to be a sensitive information. To be clear, I don't store my passwords (wp-config.php file or htpasswd files) in Dropbox account, but everything else gets copied into it as a first level backup. I also have been doing automatic backups to Amazon's S3 storage for about 5 years now, this means I can recover from most disasters quickly enough.

The reason Dropbox wins is because I don't have to pay for each minor transfer or for storing an extra gigabyte or two – and yes, every little helps even though Amazon's services are quite affordable. Another major reason I started doing backups to Dropbox is because it's a local directory – I don't have to use any extra tools to access all the backups in a simple directories/files structure. With Amazon's S3 it's also possible but setup is not as trivial.

Using Dropbox for controlling Unix systems remotely

With a few minutes and a really simple script, it's possible to setup your own mission control for all the VMs in your hosting.

For example, if you create a cronjob which looks for a particular file, you can control which DB server your systems will connect to or which directory you'll get the latest important log file copied into.

I'm also playing with services management based on the Dropbox account. If there's a file present, I keep a particular service running. As soon as the file is gone, my cronjob gracefully stops the service. A slightly more sophisticated approach involves storing services names and system names associations in a Dropbox synchronized file – this allows for more flexibility as I can specify which service I want to be running on which nodes.

Sure enough, this isn't the most straightforward way to manage your system, but such an approach can be used on the go from your iPhone. For example, I can restart a webserver by just touching a file from my iPhone, while previously I would have to find the nearest computer I trust, download SSH client, connect to the box and only then fix the problem.

Have I convinced you enough? Did you like any tips, or do you have some more perhaps? Let me know in the comments section!

pS: if you don't have a Dropbox account or perhaps if I persuaded you to create a separate one for your hosting – please use this link so that I get some extra Dropbox space for referring. Thanks!

    I would sure be into Dopbox considering all the rewards of extra space. I need it. But it doesn't appear to have direct downloads(The kind were you click and save, like on dotdeb.com) Can you tell me if there is any way to offer direct downloads through Dropbox.

  • http://www.glebreys.com Gleb Reys

    Yes, there's a way to do direct downloads with Dropbox:

    It's possible to providing download links as of quite recently, so you can have something like this:

    or this:
    https://dl.dropbox.com/s/82drr3p7bg70f98/2011-11-12%2010.36.33.jpg?dl=1
    for downloading the file.

    I'm (still) a long-time (paying) user of Dropbox, but check out Sparkleshare, you might be surprised.
