# brudi
When it comes to backup-creation there are several solutions to use.
In general everybody's doing some sort of `dump` or `tar` and backing up the results incremental with [`restic`](https://github.com/restic/restic) or similar programs.
This is why `brudi` was born. `brudi` supports several backup-methods and is configurable by a simple `yaml` file.
The advantage of `brudi` is, that you can create a backup of a source of your choice and save it with `restic` afterwards in one step.
Under the hood, `brudi` uses the given binaries like `mysqldump`, `mongodump`, `pg_dump`, `tar` or `restic`.
Using `brudi` will save you from finding yourself writing bash-scripts to create your backups.
Besides creating backups, `brudi` can also be used to restore your data from backup in an emergency.

```
### Docker
In case you don't want to install additional tools, you can also use `brudi` inside docker:
`docker run --rm -v ${HOME}/.brudi.yml:/home/brudi/.brudi.yml quay.io/mittwald/brudi mongodump --restic --cleanup`
The docker-image comes with all required binaries.
### Configuration
As already mentioned, `brudi` is configured via `.yaml`. The default path for this file is `${HOME}/.brudi.yaml`, but it's adjustable via `-c` or `--config`.
The config file itself can include environment-variables via `go-template`:
```yaml
restic:
global:
flags:
repo: "{{ .Env.RESTIC_REPOSITORY }}"
```
Since the configuration provided by the `.yaml`-file is mapped to the corresponding CLI-flags, you can adjust literally every parameter of your source backup.
Therefore you can simply refer to the official documentation for explanations on the available flags:
- [`restic`](https://restic.readthedocs.io/en/latest/manual_rest.html)
- [`tar`](https://www.gnu.org/software/tar/manual/html_section/tar_22.html)
- [`mongodump`](https://docs.mongodb.com/manual/reference/program/mongodump/#options)
- [`mysqldump`](https://dev.mysql.com/doc/refman/8.0/en/mysqldump.html#mysqldump-option-summary)
- [`pg_dump`](https://www.postgresql.org/docs/12/app-pgdump.html)
Every source has a an `additionalArgs`-key which's value is an array of strings. The value of this key is appended to the command, generated by `brudi`.
Even though `brudi` should support all cli-flags to be configured via the `.yaml`-file, there may be flags which are not.
In this case, use the `additionalArgs`-key.
It is also possible to provide more than one configuration file, for example `-c mongodump.yaml -c restic.yaml`. These configs get merged at runtime.
If available, the default config will always be laoded first and then overwritten with any values from user-specified files.
In case the same config file has been provided more than once, only the first instance will be taken into account.
#### Sources
##### Tar
```yaml
tar:
options:
flags:
create: true
gzip: true
file: /tmp/test.tar.gz
additionalArgs: []
paths:
- /tmp/testfile
hostName: autoGeneratedIfEmpty
```
Running: `brudi tar -c ${HOME}/.brudi.yml --cleanup`
Becomes the following command:
`tar -c -z -f /tmp/test.tar.gz /tmp/testfile`
All available flags to be set in the `.yaml`-configuration can be found [here](pkg/source/tar/cli.go#L7).
##### MySQLDump
```yaml
mysqldump:
options:
flags:
host: 127.0.0.1
port: 3306
password: mysqlroot
user: root
opt: true
allDatabases: true
resultFile: /tmp/test.sqldump
additionalArgs: []
```
Running: `brudi mysqldump -c ${HOME}/.brudi.yml --cleanup`
Becomes the following command:
`mysqldump --all-databases --host=127.0.0.1 --opt --password=mysqlroot --port=3306 --result-file=/tmp/test.sqldump --user=root`
All available flags to be set in the `.yaml`-configuration can be found [here](pkg/source/mysqldump/cli.go#L7).
##### MongoDump
```yaml
mongodump:
options:
flags:
host: 127.0.0.1
port: 27017
username: root
password: mongodbroot
gzip: true
archive: /tmp/dump.tar.gz
additionalArgs: []
```
Running: `brudi mongodump -c ${HOME}/.brudi.yml --cleanup`
Becomes the following command:
`mongodump --host=127.0.0.1 --port=27017 --username=root --password=mongodbroot --gzip --archive=/tmp/dump.tar.gz`
All available flags to be set in the `.yaml`-configuration can be found [here](pkg/source/mongodump/cli.go#L7).
##### PgDump
```yaml
pgdump:
options:
flags:
host: 127.0.0.1
port: 5432
password: postgresroot
username: postgresuser
dbName: postgres
file: /tmp/postgres.dump
additionalArgs: []
```
Running: `brudi pgdump -c ${HOME}/.brudi.yml --cleanup`
Becomes the following command:
`pg_dump --file=/tmp/postgres.dump --dbname=postgres --host=127.0.0.1 --port=5432 --username=postgresuser`
All available flags to be set in the `.yaml`-configuration can be found [here](pkg/source/pgdump/cli.go#L7).
###### Limitations
Unfortunately `PostgreSQL` is very strict when it comes to version-compatibility.
Therefore your `pg_dump`-binary requires the exact same version your `PostgreSQL`-server is running.
The Docker-image of `brudi` always has the latest version available for the corresponding alpine-version installed.
##### Redis
```yaml
redisdump:
options:
flags:
host: 127.0.0.1
password: redisdb
rdb: /tmp/redisdump.rdb
additionalArgs: []
```
Running: `brudi redisdump -c ${HOME}/.brudi.yml`
Becomes the following command:
`redis-cli -h 127.0.0.1 -a redisdb --rdb /tmp/redisdump.rdb bgsave`
As `redis-cli` is not a dedicated backup tool but a client for `redis`, only a limited number of flags are available by default,
as you can see [here](pkg/source/redisdump/cli.go#L7).
#### Restic
In case you're running your backup with the `--restic`-flag, you need to provide a [valid configuration for restic](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html).
You can either configure `restic` via `brudi`s `.yaml`-configuration, or via the [environment variables](https://restic.readthedocs.io/en/latest/040_backup.html#environment-variables) used by `restic`.
If you're already using `restic` in your environment, you should have everything set up perfectly to use `brudi` with `--restic`.
##### Forget
It's also possible to run `restic forget`-cmd after executing `restic backup` with `brudi` by using `--restic-forget`.
The `forget`-policy is defined in the configuration `.yaml` for brudi.
Example `.yaml`-configuration:
```yaml
restic:
global:
flags:
# you can provide the repository also via RESTIC_REPOSITORY
repo: "s3:s3.eu-central-1.amazonaws.com/your.s3.bucket/myResticRepo"
backup:
flags:
# in case there is no hostname given, the hostname from source backup is used
hostname: "MyHost"
# these paths are backuped additionally to your given source backup
paths: []
forget:
flags:
keepLast: 48
keepHourly: 24
keepDaily: 7
keepWeekly: 2
keepMonthly: 6
keepYearly: 2
ids: []
```
#### Sensitive data: Environment variables
In case you don't want to provide data directly in the `.yaml`-file, e.g. sensitive data like passwords, you can use environment-variables.
Each key of the configuration is overwritable via environment-variables. Your variable must specify the whole path to a key, seperated by `_`.
For example, given this `.yaml`:
```yaml
mongodump:
options:
flags:
username: "" # we will override this by env
password: "" # we will override this by env
host: 127.0.0.1
port: 27017
gzip: true
archive: /tmp/dump.tar.gz
```
Set your env's:
```shell
export MONGODUMP_OPTIONS_FLAGS_USERNAME="root"
export MONGODUMP_OPTIONS_FLAGS_PASSWORD="mongodbroot"
```
As soon as a variable for a key exists in your environment, the value of this environment-variable is used in favour of your `.yaml`-config.
#### Gzip support for binaries without native gzip support
The tools `mysqldump`, `pg_dump` and `redis-cli` don't natively support `gzip`. However, if the desired path for the backup file is suffixed with `.gz`,
brudi will automatically `gzip` the backup after creation and delete the uncompressed backup file. For restoration, the file will be automatically
uncompressed. Example for mysql:
```yaml
mysqldump:
options:
flags:
host: 127.0.0.1
port: 3306
password: mysqlroot
user: root
opt: true
allDatabases: true
resultFile: /tmp/test.sqldump.gz
additionalArgs: []
```
```yaml
mysqlrestore:
options:
flags:
host: 127.0.0.1
port: 3306
password: mysqlroot
user: root
Database: test
additionalArgs: []
sourceFile: /tmp/test.sqldump.gz
```
#### Restoring from backup
##### TarRestore
```yaml
tarrestore:
options:
flags:
extract: true
gzip: true
file: /tmp/test.tar.gz
target: "/"
additionalArgs: []
hostName: autoGeneratedIfEmpty
```
Running: `brudi tarrestore -c ${HOME}/.brudi.yml`
Becomes the following command:
`tar -x -z -f /tmp/test.tar.gz -C /`
##### MongoRestore
```yaml
mongorestore:
options:
flags:
host: 127.0.0.1
port: 27017
username: root
password: mongodbroot
gzip: true
archive: /tmp/dump.tar.gz
additionalArgs: []
```
Running: `brudi mongorestore -c ${HOME}/.brudi.yml `
Becomes the following command:
`mongorestore --host=127.0.0.1 --port=27017 --username=root --password=mongodbroot --gzip --archive=/tmp/dump.tar.gz`
All available flags to be set in the `.yaml`-configuration can be found [here](pkg/source/mongorestore/cli.go#L7).
##### MySQLRestore
```yaml
mysqlrestore:
options:
flags:
host: 127.0.0.1
port: 3306
password: mysqlroot
user: root
Database: test
additionalArgs: []
sourceFile: /tmp/test.sqldump
```
Running: `brudi mysqlrestore -c ${HOME}/.brudi.yml`
Becomes the following command:
`mysql --database=test --host=127.0.0.1 --password=mysqlroot --port=3306 --user=root < /tmp/test.sqldump`
All available flags to be set in the `.yaml`-configuration can be found [here](pkg/source/mysqlrestore/cli.go#L7).
##### PgRestore
Restoration for PostgreSQL databases is split into two commands, `psql` and `pgrestore`. Which one to use depends on the format of the dump created with `pg_dump`:
`psql` can be used to restore plain-text dumps, which is the default format.
`pgrestore` can be used if the `format` option of `pg_dump` was set to `tar`, `directory` or `custom`.
###### Restore using pg_restore
```yaml
pgrestore:
options:
flags:
host: 127.0.0.1
port: 5432
username: postgresuser
password: postgresroot
dbname: postgres
additionalArgs: []
sourcefile: /tmp/postgres.dump
```
Running: `brudi pgrestore -c ${HOME}/.brudi.yml`
Becomes the following command:
`pg_restore --host=127.0.0.1 --port=5432 --username=postgresuser --db-name=postgres /tmp/postgress.dump`
This command has to be used if the `format` option was set to `tar`, `directory` or `custom` in `pg_dump`.
All available flags to be set in the `.yaml`-configuration can be found [here](pkg/source/pgrestore/cli.go#L7).
###### Restore using psql
```yaml
psql:
options:
flags:
host: 127.0.0.1
port: 5432
user: postgresuser
password: postgresroot
dbname: postgres
additionalArgs: []
sourcefile: /tmp/postgres.dump
```
Running: `brudi pgrestore -c ${HOME}/.brudi.yml`
Becomes the following command:
`psql --host=127.0.0.1 --port=5432 --user=postgresuser --db-name=postgres < /tmp/postgress.dump`
This command has to be used if the `format` option was set to `plain` in `pg_dump`, which is the default.
All available flags to be set in the `.yaml`-configuration can be found [here](pkg/source/psql/cli.go#L7).
##### Restoring using restic
Backups can be pulled from a `restic` repository and applied to your server by using the `--restic` flag in your brudi command.
Example configuration for `mongorestore`:
```yaml
mongorestore:
options:
flags:
host: 127.0.0.1
port: 27017
username: root
password: mongodbroot
gzip: true
archive: /tmp/dump.tar.gz
additionalArgs: []
restic:
global:
flags:
repo: "s3:s3.eu-central-1.amazonaws.com/your.s3.bucket/myResticRepo"
restore:
flags:
target: "/"
id: "latest"
```
This will pull the latest snapshot of `/tmp/dump.tar.gz` from the repository, which `mongorestore` then uses to restore the server.
It is also possible to specify concrete snapshot-ids instead of `latest`.
