Use this tool to backup DigitalOcean droplet’s via snapshot method, on the fly!
- 20.08.17: Change
- 03.08.16: DO now automagically keeps our droplets running when snapshot is processing, so:
shutdownnow disabled by default, no downtime anymore,
If you want
- 08.01.16: now we have to use DO API V2 only, because V1 is not work anymore.
- 17.10.15: now we use DO API V2 by default, due V1 deprecation at 11.2015.
Here are some features:
- Multiple threads out of the box, no matter how many droplets you have.
- Snapshots Auto-Cleanup.
- Auto-Boot Droplet if Snapshot Event fails or encounters a bad connection exception.
- Special binaries for cron and command-line, Homebrew, and standalone installers.
- Mail notifications when a snapshot fails or the maximum number of snapshots is reached for a droplet or droplets.
- Custom mail settings (You can set Pony mail settings).
- Stop mode (automatically stop creating new snapshots when the maximum is reached).
- Timeout option for long requests or uncaught loops. Defaults to 600 seconds, but can be changed.
- Logging into selected directory.
- Verbose mode for research.
- Quiet mode for silence.
- Ruby version 2.0.0 or higher
- JRuby 18.104.22.168 or higher
- Ruby version 1.9.3 or higher

Install it yourself as:
$ gem install do_snapshot
System Wide Install (OSX, *nix):
$ sudo gem install do_snapshot
For OSX users (Homebrew Tap):
$ brew tap merqlove/do-snapshot && brew install do_snapshot $ do_snapshot -V
Standalone with one-liner:
$ wget https://assets.merqlove.ru.s3.amazonaws.com/do_snapshot/do_snapshot.tgz && sudo tar -xzf do_snapshot.tgz /usr/local/lib/ && sudo ln -s /usr/local/lib/do_snapshot/bin/do_snapshot /usr/local/bin/do_snapshot
Standalone pack for Unix/Linux users: Download
$ wget https://assets.merqlove.ru.s3.amazonaws.com/do_snapshot/do_snapshot.tgz # if not done. # Example Install into /usr/local $ tar -xzf do_snapshot.tgz /usr/local/ && ln -s /usr/local/do_snapshot/bin/do_snapshot /usr/local/bin/do_snapshot $ do_snapshot help
Standalone Zip pack for others: Download
Mainly it’s pretty simple:
$ do_snapshot --only 123456 -k 5 -c -v
Digitalocean API V2 (default):
You’ll need to generate an access token in Digital Ocean’s control panel at https://cloud.digitalocean.com/settings/applications
$ export DIGITAL_OCEAN_ACCESS_TOKEN="SOMETOKEN"
If you want to set keys without environment, than set it via options when you run do_snapshot:
$ do_snapshot --digital-ocean-access-token YOURLONGTOKEN

keeping only 5 latest snapshots and cleanup older after new one is created. If creation of snapshots failed no one will be deleted. By default we keeping
$ do_snapshot --keep 5 -c
Keep latest 3 from selected droplet:
$ do_snapshot --only 123456 --keep 3
Working with all except droplets:
$ do_snapshot --exclude 123456 123457
Keep latest 5 snapshots, send mail notification instead of creating new one:
$ do_snapshot --keep 10 --stop --mail to:email@example.com
E-mail notifications disabled out of the box. For working mailer you need to set e-mail settings via run options.

You can ask, “Why you made this tool?”
- First. I needed stable tool, which can provide for me automatic Snapshot feature for all of my Droplets via Cron planner.
- I don’t want to think how much snapshots for each droplet i have.
- I don’t wont to sleep when my droplets Offline!!! And i wanted tool which can BOOT back droplets, which failed to snapshot.
- Also i want to understand what’s going on if there some error. Mail is my choice. But logs also good.
- And … sure ;) We want to do it fast as rocket! :)
- more more more…
- So this tool can save a lot of time for people.
