My favorite backup utility right now has to be Syncthing. It is simple to implement and use and there is no reliance on a third party (e.g. Google Drive, Dropbox, etc…).
We should know by now that one backup is never enough. Once upon a time I bought a 64 GiB thumb drive from Amazon for about $40 and this served as my “~daily rsync” backup. This was all good and well and pretty damn nifty to have a perfect, bootable, replica of my home pc attached to my hip all day.
However, when I’m not playing system admin at home, I’m usually rock climbing somewhere in the Atlanta-Birmingham-Chattanooga Triangle. Needless to say I smashed a few of those aforementioned thumb drives in the past few years.
Most of us carry dang powerful pocket-god computers around every day, why not backup to that!? Many times I experimented with Google Drive (grive) and always seemed to come up dissatisfied. I even went so far as to tinker (and have some success) with a SSH
- Rsync combo through a home WiFi network.
But there is a better way my FOSS friends! Hosting your own local server to
volley backups to and fro from doesn’t have to be as complicated as it seems.
Yes, maybe ownCloud is a bit more pollished and BTsync can do similar things. But, Syncthing is open sourced(and free) and is essentially effortless to set up.
Maybe you want the simple route of syncing your phone’s pictures back to your desktop:
1) Gather the things:
* Install the [Syncthing Android App](https://play.google.com/store/apps/details?id=com.nutomic.syncthingandroid) * Install the [official Syncthing Arch package](https://www.archlinux.org/packages/?name=syncthing)
2) Prepare your phone:
* Open the app and add the relevant folder contianing your pictures * Swipe over to ```DEVICES``` and tap the ```+``` on the top-right corner
3) Ready your PC:
* On your desktop do ```$ systemctl --user start syncthing``` * Navigate to ```localhost://8384``` in your pc's web browser * Click ```Actions``` then ```Show ID```
4) Connect the devices
* Tap the QR-Code icon on your phone * Snap a pic of the QR-Code on your desktop screen
5) You can then go back on your phone and select which folders to share with the new device.
Likewise, do some of that in reverse and sync all of ~/home to /storage/ext_sd. Though, for a copmete backup I’d recommend backing up your system settings to somewhere in ~/home with a simple cron job as well.
Seemingly contrary to Android 4.4.x KitKat’s limitations regarding 3rd party apps writing to the external SD Card, there is a work around for this. You can install and app like OI File Manager to create a folder in /storage/ext_sd. Technically the app “owns” the folder it creates, and thus non-root apps can write there. Whatever folder you create, maybe /storage/ext_sd/pc-backup, just choos that to sync to ~/home.
Everyday use is easy too. I have a shell alias set up to A) connect to WiFi via netctl, B) deploys my firewall via iptables, and C) start the syncthing server. All I have to do then is launch the app on my phone while the PC / Laptop are connected to the same WiFi network.
The initial sync will, of course, take quite a while and very long if you have a lot of data. However, I’ve found it pretty reliable and snappy after that. Even if you miss a few days, chances are if you launch the app while you’re grinding away at your deask, your files can sync up nicely before bed.
All in all syncthing is simple, savy, easy to use, and just plain gets the job done! Cheers to the devs!
