# Prerequisites
## Prerequisites
You must have a working DB server or container available for this to work properly, it does not provide server functionality!
# Installation
## Installation
Automated builds of the image are available on [Docker Hub](https://hub.docker.com/r/tiredofit/db-backup) and is the recommended
method of installation.
```bash
docker pull tiredofit/db-backup:latest
```
# Quick Start
### Quick Start
* The quickest way to get started is using [docker-compose](https://docs.docker.com/compose/). See the examples folder for a working [docker-compose.yml](examples/docker-compose.yml) that can be modified for development or production use.
@@ -69,46 +77,45 @@ docker pull tiredofit/db-backup:latest
> **NOTE**: If you are using this with a docker-compose file along with a seperate SQL container, take care not to set the variables to backup immediately, more so have it delay execution for a minute, otherwise you will get a failed first backup.
# Configuration
## Configuration
## Data-Volumes
### Data-Volumes
The following directories are used for configuration and can be mapped for persistent storage.
| Directory | Description |
|-----------|-------------|
| `/backup` | Backups |
| `/assets/custom-scripts` | *Optional* Put custom scripts in this directory to execute after backup operations
| Directory | Description |
| ------------------------ | ---------------------------------------------------------------------------------- |
| `/backup` | Backups |
| `/assets/custom-scripts` | *Optional* Put custom scripts in this directory to execute after backup operations |
## Environment Variables
### Environment Variables
*If you are trying to backup a database that doesn't have a user or a password (you should!) make sure you set `CONTAINER_ENABLE_DOCKER_SECRETS=FALSE`*
Along with the Environment Variables from the [Base image](https://hub.docker.com/r/tiredofit/alpine), below is the complete list of available options that can be used to customize your installation.
| Parameter | Description |
|-----------|-------------|
| `BACKUP_LOCATION` | Backup to `FILESYSTEM` or `S3` compatible services like S3, Minio, Wasabi - Default `FILESYSTEM`
| `COMPRESSION` | Use either Gzip `GZ`, Bzip2 `BZ`, XZip `XZ`, ZSTD `ZSTD` or none `NONE` - Default `GZ`
| `COMPRESSION_LEVEL` | Numberical value of what level of compression to use, most allow `1` to `9` except for `ZSTD` which allows for `1` to `19` - Default `3` |
| `DB_TYPE` | Type of DB Server to backup `couch` `influx` `mysql` `pgsql` `mongo` `redis` |
| `DB_HOST` | Server Hostname e.g. `mariadb`
| `DB_NAME` | Schema Name e.g. `database`
| `DB_USER` | username for the database - use `root` to backup all MySQL of them.
| `DB_PASS` | (optional if DB doesn't require it) password for the database
| `DB_PORT` | (optional) Set port to connect to DB_HOST. Defaults are provided
| `DB_DUMP_FREQ` | How often to do a dump, in minutes. Defaults to 1440 minutes, or once per day.
| `DB_DUMP_BEGIN` | What time to do the first dump. Defaults to immediate. Must be in one of two formats
| | Absolute HHMM, e.g. `2330` or `0415`
| | Relative +MM, i.e. how many minutes after starting the container, e.g. `+0` (immediate), `+10` (in 10 minutes), or `+90` in an hour and a half
| `DB_CLEANUP_TIME` | Value in minutes to delete old backups (only fired when dump freqency fires). 1440 would delete anything above 1 day old. You don't need to set this variable if you want to hold onto everything.
| `DEBUG_MODE` | If set to `true`, print copious shell script messages to the container log. Otherwise only basic messages are printed.
| `EXTRA_OPTS` | If you need to pass extra arguments to the backup command, add them here e.g. "--extra-command"
| `MD5` | Generate MD5 Sum in Directory, `TRUE` or `FALSE` - Default `TRUE`
| `PARALLEL_COMPRESSION` | Use multiple cores when compressing backups `TRUE` or `FALSE` - Default `TRUE` |
| `SPLIT_DB` | If using root as username and multiple DBs on system, set to TRUE to create Seperate DB Backups instead of all in one. - Default `FALSE` |
