Use this tool to backup DigitalOcean droplet's via snapshot method, on the fly!

API Changes:

• 20.08.17: Change Barge to DropletKit. Release 1.0.0.
• 03.08.16: DO now automagically keeps our droplets running when snapshot is processing, so:
  Added options --shutdown, --no-shutdown.
  shutdown now disabled by default, no downtime anymore, YES!
  If you want shutdown back use --shutdown option.
• 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.

Usage

Mainly it's pretty simple:

$ do_snapshot --only 123456 -k 5 -c -v

Setup

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   

How-To

Tutorials:

• Automate Taking Snapshots of Your DigitalOcean Droplets with DOSnapshot , Tyler Longren
• How to Automate Taking Digital Ocean Droplet Snaphot with DoSnapShot Script, Arun Kumar

Here we 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 10 droplets.

$ 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:yourmail@example.com

E-mail notifications disabled out of the box. For working mailer you need to set e-mail settings via run options.

--mail to:mail@somehost.com from:from@host.com --smtp address:smtp.gmail.com port:25 user_name:someuser password:somepassword

Cron example

0 4 * * 7 . /.../.digitalocean_keys && /.../bin/do_snapshot -k 5 -m to:TO from:FROM -t address:HOST user_name:LOGIN password:PASSWORD port:2525 -q -c

Real world example

$ bin/do_snapshot --only 123456 -k 3 -c -m to:TO from:FROM -t address:HOST user_name:LOGIN password:PASSWORD port:2525 -v

Description:
  `do_snapshot` able to create and cleanup snapshots on your droplets.

  You can optionally specify parameters to select or exclude some droplets.   

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.
