dbee

dbee helps you to backup and restore your PostreSQL database trough S3 compatible servers (like Minio). Quickly save a dump from a server and init a new database on another server with a few commands.

Install

With NPM

npm i -g git+https://github.com/5ika/dbee.git

Command dbee will be globally available on your system.

Use

Quick-start

1. Add an S3 server

dbee s3 add mys3 minio.example.org --accessKey myaccesskey --secretKey mysecretkey

mys3 will be the reference name for this S3 server

2. Add a PostgreSQL server

dbee psql add mypsql psql.example.org --username myuser --password mypassword

mypsql will be the reference name for this PSQL server.

If no password is provided at this step, it will be asked when needed.

3. Create a database dump

dbee bckp mypsql/mydbname

A dump of mydbname database will be uploaded to mys3 S3 server.

4. Init a new database from dump

dbee ls # List available dumps on S3 server
dbee init mydbname-2021-07-29T15:10:19.748Z.bak myotherpsql/mynewdb

Commands

dbee s3 add <s3Name> <host>                           Add S3 server
dbee s3 rm <s3Name>                                   Remove S3 server from config
dbee s3 ls                                            List S3 servers
dbee psql add <psqlName> <host>                       Add Postgres servers
dbee psql ls                                          List Postgress servers
dbee psql rm <psqlName>                               Remove Postgres server from config
dbee ls [s3Name]									                    List databases available on S3 server
dbee rm [s3Name/]<fileName>                           Remove database dump from S3 server
dbee bckp [psqlName/]<dbName> [s3Name]                Backup database to S3
dbee init [s3Name/]<fileName> [psqlName/]<dbName>     Restore database from S3

Advanced use

Options for S3 server

It is possible to provide some additional options for the S3 connection:

• --port or -p: Specify another port than the default one (443)
• --useSSL or -s: Use an SSL connection to the server
• --bucket or -b: Specify another bucket name than the default one (dbee)

Multiple S3 servers

When only one S3 server is configured, it's not necessary to specify it:

dbee ls

But when there is more than one, it is necessary:

dbee ls myminio

Options for PostgreSQL server

It is possible to provide some additional options for the PostgreSQL connection:

• --port or -p: Specify another port than the default one (5432)
• --useSSL or -s: Use an SSL connection to the server
• --timescale or -t: Specify that the server uses TimescaleDB extension (useful for database creation)

PostgreSQL server on localhost

When no psqlName is provided, dbee take a default configuration for PostgreSQL server as following:

{
  "host": "localhost",
  "username": "postgres",
  "password": null,
  "useSSL": false,
  "port": 5432
}

It permits commands like:

dbee bckp mydbname
dbee init mydbname-2021-07-29T15:10:19.748Z.bak mynewdb

Build

A standalone executable binary can be built with pkg:

yarn build

Executable is then available in the dist/ directory.
