datadb

Effortless program data deployment and backup

Installation

  • Clone: git clone http://gitlab.xmopx.net/dave/datadb-cli.git datadb-cli
  • Install prereqs: cd datadb-cli ; pip3 install -r requirements.txt
  • Install: python3 setup.py install

Requirements

Just python3 and requests.

Usage

Setup

For one, this is beta and some things are hard-coded. In datadb.py it is recommended to change the DATADB_HTTP_API URL. This URL should be the cgi-bin path of an http server running datadb-scripts.

Next, a config file must be created for each directory to be restored/backed up. It lives at /etc/datadb.ini and contains many entires of this format:

[profile_name]
uri=<procotol>://<server>/<backup_name>
dir=/local/path
keep=5
auth=username:password
restore_preexec=
restore_postexec=
export_preexec=
export_postexec=

Each [section] defines one backup task. At present, all fields must be there even if their value is blank.

Fields:

uri: Destination/source for this instance's data. Must be this format: <procotol>://<server>/<backup name>

Valid protocols:

  • rsync - rsync executed over SSH. The local dir will be synced with the remote backup dir using rsync. Vice-versa for restores.
  • archive - tar.gz data streamed over HTTP. The local dir will be tarred and PUT to the backup server's remote dir via http. Vice-versa for restores. Recommended only for smaller datasets.

dir: Local dir for this backup/restore

keep: Number of historical copies to keep on remote server

auth: Not implemented. Username:password string to use while contacting the datadb via HTTP.

restore_preexec: Not implemented. Shell command to exec before pulling/restoring data.

restore_postexec: Not implemented. Shell command to exec after pulling/restoring data. For example, loading a mysql dump

export_preexec: Not implemented. Shell command to exec before pushing data. For example, dumping a mysql database to a file in the backup dir.

export_postexec: Not implemented. Shell command to exec after pushing data

Assumptions

Datadb makes some assumptions about it's environment.

  • rsync, ssh, tar, and curl commands are assumed to be in $PATH
  • For rsync operations, the ssh private key file at /root/.ssh/datadb.key is used.

CLI Usage

  • Restore from backup: datadb [--force] <profile_name> restore

Restore operations have a degree of sanity checking. Upon a successful restore, a file named .datadb.lock will be created in the local dir. Datadb checks for this file before doing restore operations, to prevent overwriting live data with an old backup. This check can be overridden with the --force command line option.

  • Backup to remote server: datadb <profile_name> backup
  • Check status: datadb <profile_name> status

Command line usage is agnostic to the underlying transport protocol used.

TODO

  • Fix hard coded stuff mentioned above
  • Support config file-less usage
  • Sync all command
  • Option to override config path
  • Nicer config parsing
  • Implement security
  • Implement pre/post exec functions
