Automated Offline Or Live Snapshots Of Digitalocean Droplets

Project description

dobackup

Downloads

Simple Automated offline snapshots of digitalocean droplets utilising [python-digitalocean](https://github.com/koalalorenzo/python-digitalocean). The script safely shutdowns a given droplet or all droplets with a give tag then performs snapshots of them, Then it turns them back on. Every step is logged as well as displayed in the console output. The script is designed to be used as a cron job as well. If any error occurs the script logs it then exits with exit code of 1. Very useful feature to ensure that the backups are successfully completed. I use it to delete older backups only if new one is successful and to use a 'healthchecks' service to get notified if a backup failed. (see cron examples)

dobackup

Installation

Install as a user without sudo. This installs it in ~/.local/bin/ make sure this path is in your $PATH.

python3 -m pip install --user -U dobackup

If not found, add the following to your .bashrc or .zshrc

# Add to PATH to Install and run programs with "pip install --user"
export PATH=$PATH:~/.local/bin

Usage

Initialise

Store the api access token in .token file by running '--init' and providing the token string.

dobackup --init
# Paste the digitalocean token string, press enter
# If you have multiple accounts, paste each- press enter, so on
# When done, just press enter to submit an empty string
# The sequence of these tokens (0,1,2) will be later used to "use" the tokens

To use one of the stored tokens, specify it's index after "dobackup ",

dobackup 0      # 0 is implicit
dobackup 1      # will use token 1
dobackup 2      # will use token 2

Display Information

Display Information about droplets and snapshots using --list commands. Examples

dobackup --list-droplets
dobackup --list-snaps
dobackup --list-backups  # snaps created using this tool
dobakcup --list-older_than 7    # lists backup taken by dobackup that are older than 7 days
dobackup --list-tags
dobackup --list-tagged   # list tagged servers with the tag 'dobackup'

Use Tags (optional)

Use tags to backup multiple servers at ones. Use existing tags or create new. Default tag is 'dobackup' . To tag a server with a 'dobakup' tag.

dobackup --tag-server ubuntu-18-04  # '--tag-name dobackup' is implicit

To tag a server with 'web-servers' tag.

dobackup --tag-server ubuntu-18-04  --tag-name web-servers

NOTE: In 2.0, --'tag-name'-- is appended to the backup name, instead of hardcoded str '--dobackup--'. The default value of tag_name is still 'dobackup'. Now we can use --tag-name along with --list-backups, --list-older-than, --delete-older-than. Now we can keep the backups of droplets with lets say 'tag1' for 5 days and 'tag2' for 10 days. example command. "--delete-older-than 5 --tag-name 'tag1'" , "--delete-older-than 10 --tag-name 'tag2'"

Perform Backups

To backup a server using it's name or id.

dobackup --backup ubuntu-18-04
dobackup --backup 1929129
dobackup --live-backup ubuntu-18-04       # live backup, backup without shutting down the vm
dobackup --backup ubuntu-18-04 --keep     # this won't be deleted with '--delete-older-than'

To backup all servers that have a given tag.

dobackup --backup-all   # --tag-name dobackup    is implicit
dobackup --backup-all --tag-name web-servers

To set a cron job, to backup all 'tagged' servers and auto delete old backups, if backups were successful

0 1 * * * ~/.local/bin/dobackup --backup-all && ~/.local/bin/dobackup --delete-older-than 7

Using amazing utility healthchecks. to get notified if an error occurred during the process.

0 1 * * * ~/.local/bin/dobackup --backup-all && ~/.local/bin/dobackup --delete-older-than 7 && wget -O/dev/null https://hc-ping.com/your-string

Perform Restore

To restore a server using it's name or id and snapshot's name or id

dobackup --restore-droplet ubuntu-18-04 --restore-to "ubuntu-18-04--dobackup--2018-06-01 14:36:07"

Delete Old Backups

To delete a specific snapshot.

dobackup --delete-snap "ubuntu-1gb-sgp1-01--dobackup--2018-05-31 17:43:11"   # put snap name or id
dobackup --delete-snap "111111111,222222222,3333333333"     # comma seperated multiple ids or names

To delete all old backups taken with dobackup.

# delete snapshots older than 14 days with '--dobackup--' in their names
# WILL NOT delete snapshots with '--dobackup-keep--' in their names
dobackup --delete-older-than 14
