## Prerequisites and Assumptions
- You must have a working connection to one of the supported DB Servers and appropriate credentials
## Installation
### Build from Source
Clone this repository and build the image with `docker build (imagename) .`
### Prebuilt Images
Builds of the image are available on [Docker Hub](https://hub.docker.com/r/tiredofit/db-backup)
Builds of the image are also available on the [Github Container Registry](https://github.com/tiredofit/docker-db-backup/pkgs/container/docker-db-backup)
```bash
docker pull ghcr.io/tiredofit/docker-db-backup:(imagetag)
```
The following image tags are available along with their tagged release based on what's written in the [Changelog](CHANGELOG.md):
| Alpine Base | Tag |
| ----------- | --------- |
| latest | `:latest` |
```bash
docker pull docker.io/tiredofit/db-backup:(imagetag)
```
#### Multi Architecture
Images are built primarily for `amd64` architecture, and may also include builds for `arm/v7`, `arm64` and others. These variants are all unsupported. Consider [sponsoring](https://www.tiredofit.ca/sponsor) my work so that I can work with various hardware. To see if this image supports multiple architectures, type `docker manifest (image):(tag)`
## Configuration
### Quick Start
- The quickest way to get started is using [docker-compose](https://docs.docker.com/compose/). See the examples folder for a series of example compose.yml that can be modified for development or production use.
- Set various [environment variables](#environment-variables) to understand the capabilities of this image.
- Map [persistent storage](#data-volumes) for access to configuration and data files for backup.
### Persistent Storage
The following directories are used for configuration and can be mapped for persistent storage.
| Directory | Description |
| ---------------------- | ----------------------------------------------------------------------------------- |
| `/backup` | Backups |
| `/assets/scripts/pre` | _Optional_ Put custom scripts in this directory to execute before backup operations |
| `/assets/scripts/post` | _Optional_ Put custom scripts in this directory to execute after backup operations |
| `/logs` | _Optional_ Logfiles for backup jobs |
### Environment Variables
#### Base Images used
This image relies on an [Alpine Linux](https://hub.docker.com/r/tiredofit/alpine) base image that relies on an [init system](https://github.com/just-containers/s6-overlay) for added capabilities. Outgoing SMTP capabilities are handled via `msmtp`. Individual container performance monitoring is performed by [zabbix-agent](https://zabbix.org). Additional tools include: `bash`,`curl`,`less`,`logrotate`, `nano`.
Be sure to view the following repositories to understand all the customizable options:

| `DEFAULT_PRE_SCRIPT` | Fill this variable in with a command to execute pre backing up | |
| `DEFAULT_POST_SCRIPT` | Fill this variable in with a command to execute post backing up | |
###### Pre Backup
If you want to execute a custom script before a backup starts, you can drop bash scripts with the extension of `.sh` in the location defined in `DB01_SCRIPT_LOCATION_PRE`. See the following example to utilize:
```bash
$ cat pre-script.sh
##!/bin/bash
# #### Example Pre Script
# #### $1=DBXX_TYPE (Type of Backup)
# #### $2=DBXX_HOST (Backup Host)
# #### $3=DBXX_NAME (Name of Database backed up
# #### $4=BACKUP START TIME (Seconds since Epoch)
# #### $5=BACKUP FILENAME (Filename)
echo "${1} Backup Starting on ${2} for ${3} at ${4}. Filename: ${5}"
```
## script DBXX_TYPE DBXX_HOST DBXX_NAME STARTEPOCH BACKUP_FILENAME
${f} "${backup_job_db_type}" "${backup_job_db_host}" "${backup_job_db_name}" "${backup_routines_start_time}" "${backup_job_file}"
Outputs the following on the console:
`mysql Backup Starting on example-db for example at 1647370800. Filename: mysql_example_example-db_202200315-000000.sql.bz2`
###### Post backup
If you want to execute a custom script at the end of a backup, you can drop bash scripts with the extension of `.sh` in the location defined in `DB01_SCRIPT_LOCATION_POST`. Also to support legacy users `/assets/custom-scripts` is also scanned and executed.See the following example to utilize:
```bash
$ cat post-script.sh
##!/bin/bash
# #### Example Post Script
# #### $1=EXIT_CODE (After running backup routine)
# #### $2=DBXX_TYPE (Type of Backup)
# #### $3=DBXX_HOST (Backup Host)
# #### #4=DBXX_NAME (Name of Database backed up
# #### $5=BACKUP START TIME (Seconds since Epoch)
# #### $6=BACKUP FINISH TIME (Seconds since Epoch)
# #### $7=BACKUP TOTAL TIME (Seconds between Start and Finish)
# #### $8=BACKUP FILENAME (Filename)
# #### $9=BACKUP FILESIZE
# #### $10=HASH (If CHECKSUM enabled)
# #### $11=MOVE_EXIT_CODE
echo "${1} ${2} Backup Completed on ${3} for ${4} on ${5} ending ${6} for a duration of ${7} seconds. Filename: ${8} Size: ${9} bytes MD5: ${10}"
```
## script EXIT_CODE DB_TYPE DB_HOST DB_NAME STARTEPOCH FINISHEPOCH DURATIONEPOCH BACKUP_FILENAME FILESIZE CHECKSUMVALUE
${f} "${exit_code}" "${dbtype}" "${backup_job_db_host}" "${backup_job_db_name}" "${backup_routines_start_time}" "${backup_routines_finish_time}" "${backup_routines_total_time}" "${backup_job_file}" "${filesize}" "${checksum_value}" "${move_exit_code}
Outputs the following on the console:
`0 mysql Backup Completed on example-db for example on 1647370800 ending 1647370920 for a duration of 120 seconds. Filename: mysql_example_example-db_202200315-000000.sql.bz2 Size: 7795 bytes Hash: 952fbaafa30437494fdf3989a662cd40 0`
If you wish to change the size value from bytes to megabytes set environment variable `DB01_SIZE_VALUE=megabytes`
You must make your scripts executable otherwise there is an internal check that will skip trying to run it otherwise.
If for some reason your filesystem or host is not detecting it right, use the environment variable `DB01_POST_SCRIPT_SKIP_X_VERIFY=TRUE` to bypass.
#### Job Backup Options
If `DEFAULT_` variables are set and you do not wish for the settings to carry over into your jobs, you can set the appropriate environment variable with the value of `unset`.
Otherwise, override them per backup job. Additional backup jobs can be scheduled by using `DB02_`,`DB03_`,`DB04_` ... prefixes. See [Specific Database Options](#specific-database-options) which may overrule this list.

| `DB01_PRE_SCRIPT` | Fill this variable in with a command to execute pre backing up | |
| `DB01_POST_SCRIPT` | Fill this variable in with a command to execute post backing up | |
###### Pre Backup
If you want to execute a custom script before a backup starts, you can drop bash scripts with the extension of `.sh` in the location defined in `DB01_SCRIPT_LOCATION_PRE`. See the following example to utilize:
```bash
$ cat pre-script.sh
##!/bin/bash
# #### Example Pre Script
# #### $1=DB01_TYPE (Type of Backup)
# #### $2=DB01_HOST (Backup Host)
# #### $3=DB01_NAME (Name of Database backed up
# #### $4=BACKUP START TIME (Seconds since Epoch)
# #### $5=BACKUP FILENAME (Filename)
echo "${1} Backup Starting on ${2} for ${3} at ${4}. Filename: ${5}"
```
## script DB01_TYPE DB01_HOST DB01_NAME STARTEPOCH BACKUP_FILENAME
${f} "${backup_job_db_type}" "${backup_job_db_host}" "${backup_job_db_name}" "${backup_routines_start_time}" "${backup_job_filename}"
Outputs the following on the console:
`mysql Backup Starting on example-db for example at 1647370800. Filename: mysql_example_example-db_202200315-000000.sql.bz2`
###### Post backup
If you want to execute a custom script at the end of a backup, you can drop bash scripts with the extension of `.sh` in the location defined in `DB01_SCRIPT_LOCATION_POST`. Also to support legacy users `/assets/custom-scripts` is also scanned and executed.See the following example to utilize:
```bash
$ cat post-script.sh
##!/bin/bash
# #### Example Post Script
# #### $1=EXIT_CODE (After running backup routine)
# #### $2=DB_TYPE (Type of Backup)
# #### $3=DB_HOST (Backup Host)
# #### #4=DB_NAME (Name of Database backed up
# #### $5=BACKUP START TIME (Seconds since Epoch)
# #### $6=BACKUP FINISH TIME (Seconds since Epoch)
# #### $7=BACKUP TOTAL TIME (Seconds between Start and Finish)
# #### $8=BACKUP FILENAME (Filename)
# #### $9=BACKUP FILESIZE
# #### $10=HASH (If CHECKSUM enabled)
# #### $11=MOVE_EXIT_CODE
echo "${1} ${2} Backup Completed on ${3} for ${4} on ${5} ending ${6} for a duration of ${7} seconds. Filename: ${8} Size: ${9} bytes MD5: ${10}"
```
## script EXIT_CODE DB_TYPE DB_HOST DB_NAME STARTEPOCH FINISHEPOCH DURATIONEPOCH BACKUP_FILENAME FILESIZE CHECKSUMVALUE
${f} "${exit_code}" "${dbtype}" "${dbhost}" "${dbname}" "${backup_routines_start_time}" "${backup_routines_finish_time}" "${backup_routines_total_time}" "${backup_job_filename}" "${filesize}" "${checksum_value}" "${move_exit_code}
Outputs the following on the console:
`0 mysql Backup Completed on example-db for example on 1647370800 ending 1647370920 for a duration of 120 seconds. Filename: mysql_example_example-db_202200315-000000.sql.bz2 Size: 7795 bytes Hash: 952fbaafa30437494fdf3989a662cd40 0`
If you wish to change the size value from bytes to megabytes set environment variable `DB01_SIZE_VALUE=megabytes`
You must make your scripts executable otherwise there is an internal check that will skip trying to run it otherwise.
If for some reason your filesystem or host is not detecting it right, use the environment variable `DB01_POST_SCRIPT_SKIP_X_VERIFY=TRUE` to bypass.

## Maintenance
### Shell Access
For debugging and maintenance purposes you may want access the containers shell.
`bash
docker exec -it (whatever your container name is) bash
`
### Manual Backups
Manual Backups can be performed by entering the container and typing `backup-now`. This will execute all the backup tasks that are scheduled by means of the `BACKUPXX_` variables. Alternatively if you wanted to execute a job on its own you could simply type `backup01-now` (or whatever your number would be). There is no concurrency, and jobs will be executed sequentially.
- Recently there was a request to have the container work with Kubernetes cron scheduling. This can theoretically be accomplished by setting the container `MODE=MANUAL` and then setting `MANUAL_RUN_FOREVER=FALSE` - You would also want to disable a few features from the upstream base images specifically `CONTAINER_ENABLE_SCHEDULING` and `CONTAINER_ENABLE_MONITORING`. This should allow the container to start, execute a backup by executing and then exit cleanly. An alternative way to running the script is to execute `/etc/services.available/10-db-backup/run`.
### Restoring Databases
Entering in the container and executing `restore` will execute a menu based script to restore your backups - MariaDB, Postgres, and Mongo supported.
You will be presented with a series of menus allowing you to choose:
- What file to restore
- What type of DB Backup
- What Host to restore to
- What Database Name to restore to
- What Database User to use
- What Database Password to use
- What Database Port to use
The image will try to do auto detection based on the filename for the type, hostname, and database name.
The image will also allow you to use environment variables or Docker secrets used to backup the images
The script can also be executed skipping the interactive mode by using the following syntax/
`restore `
If you only enter some of the arguments you will be prompted to fill them in.
