NAME
baka - do files and databases backup.
SYNOPSIS
baka [--version] [--help | help] [-c | --config=<file>]
<command> [<options>...]
DESCRIPTION
baka allows you to backup MariaDB/MySQL and PostgreSQL directories and databases. baka is designed to perform full backups.
baka is based on handling entries. Processing can be started at once for everyone entries, either only for the selected ones, or for all but the excluded ones.
baka implements only the mechanism for creating archives with files and database dumps and transferring these files to remote storage using third-party tools (such as rsync, s3cmd). To perform scheduled backups, the command baka it is recommended to install it in the operating system task scheduler. For example cron. Examples of usage are in the section EXAMPLES.
From the above points and the possibility of customizing a separate entry, it follows that with using baka, you can configure the backup system quite flexibly.
ATTENTION: Despite the laudatory description above, baka should not be regarded as professional backup solutions. Please don't use baka in production-like environments.
Basic concepts:
Entry
Entity describing the elements to be acted upon. There can be any number of these entities. For a more detailed description, see section CONFIGURATION FILES.
OPTIONS
-c, --config=<file> source baka.conf file.
--version print version and exit.
--help, help print help message and exit.
COMMANDS
backup
Do backup right now. Available options:
-i, --ignore=<entry> run backup for all entries, except ignored.
-e, --entry=<entry> run backup for selected entry.
--local force local backup.
--no-verify don't check archives integrity.
--dry-run configuration test.
--remove remove old backups (forced).
--help, help print help message and exit.
list
List backup entries. Available options:
-v, --verbose print entries list verbosely (table view).
--help, help print help message and exit.
remove
Remove old local backups (older than $livetime days). Backup livetime is set in baka.conf.
-l, --list print a list of files to be deleted.
-f, --force force remove.
--help, help show this message and exit.
CONFIGURATION FILES
Configuration files contain variables that set operating parameters for the entire application or for processing an individual job.
Some of the config variables are arrays. below each variable is labeled with its type. Array parameters allow you to specify multiple instances of data, which will be combined into an array during parsing. For instance:
copy = /path/to/file
copy = /path/to/another_file
The end result is an 'copy' array with the values '( /path/to/file /path/to/another_file )'.
Some parameters are required, some are not. Also parameters can only be found in certain contexts. There are only two contexts: baka.conf and entry.
baka.conf Default path: /etc/baka/baka.conf. This contains the values
for the global baka settings.
entry By default entries is stored into /etc/baka/entries/ directory
in separated files. File name does not matter. Here you can set
the parameters for backuping the requred data set.
PARAMETERS SUMMARY
lo Required: yes
Type: string
Context: baka.conf
Default: /var/log/baka
Path to log file.
log_format Required: yes
Type: string
Context: baka.conf
Default: [%d %b %Y %T %z] {log}
Log format. It actually is 'date' format string
(see date(1)) with special syntax (palceholdes):
{log} will be replaced with actual log string.
filename_format Required: yes
Type: string
Context: baka.conf
Default: {prefix}{name}_%Y%m%d-%H%M
Filename format. Similar to log_format.
Special syntax (placeholders):
{name} replaces with file, directory or database
name.
{prefix} replaces with prefix specified in entry
file or by autoprefix (based on entry
file name).
autoprefix Required: no
Type: boolean
Context: baka.conf
Default: true
Automatic prefix for filenames. Prefix is based on
entry file name.
dir_per_date Required: yes
Type: string
Context: baka.conf
Default: %Y-%m-%d
Directory hierarchy definer. Actually is 'date' format
string but interpretated as path. With this variable you
can store your backups in hierarchy like this
('%Y/%m/%d' -- year, month, day or any other):
2022/
|___01/
| |____01/
| |____02/
| |...
|___02/
|___01/
livetime Required: yes
Type: integer
Context: baka.conf
Default: 30
The livetime of old backups (number of days).
allow_commands Required: no
Type: boolean
Context: baka.conf
Default: false
Flag for executing commands in Entries.
local Required: must be in at least one context
Type: string
Context: baka.conf, entry
Default: no default
Local storage. Contains path to local directory.
remote Required: must be in at least one context
Type: string
Context: baka.conf, entry
Default: 'none'
Remote storage. Here should be the address of the remote
storage. Standard URI is supported:
[schema]://[user[:password]]@[host[:port]]/[path]
Password can contain URL-encoded characters. See
https://en.wikipedia.org/wiki/Percent-encoding
Supported schemas:
rsync upload files to remove server via rsync
over SSH.
s3 upload files to Amazon S3 or S3 compatible
storage via s3cmd tool.
Examples:
rsync://backupuser@123.45.67.89:2022/backups
s3://mybucketname
In order to use rsync, you need a SSH-key. And for s3cmd
you need to configure ~/.s3cmd file. See docs:
https://s3tools.org/s3cmd-howto
Send me feature request if you want to use another
schemas. See AUTHOR below.
prefix Required: no
Type: string
Context: entry
Default: no default
Filename prefix. Overrides 'autoprefix'.
archive Required: no
Type: array
Context: entry
Default: no default
Path to file or directory to archive (.tar.gz)
You can exclude some files with 'exclude' variable.
exclude Required: no
Type: array
Context: entry
Default: no default
Exclude some files or directories for tar (does not
work with 'copy'). You can list files separated by commas
or use multiple variable. For example, this is valid:
exclude = backups,logs,env,__pycache__
exclude = node_modules,.environment
copy Required: no
Type: array
Context: entry
Default: no default
Copy files or directories without compression using 'cp'.
Destination filename will be modified by filename_format.
For example 'myentry.conf':
local = /backups
copy = /srv/http/example.org/data.zip
In result:
/backups/2022-01-01/myentry.conf_data_20220101-0012.zip
database Required: no
Type: array
Context: entry
Default: no default
Database URI. Supported databases: MySQL/MariaDB, PostgreSQL.
URI format:
[schema]://[user[:password]@[host[:port]/[database]
Password can contain URL-encoded characters.
For example:
database = mysql://myuser:myp%40%24%24@localhost:/mydb
cammand Required: no
Type: array
Context: entry
Default: no deafult
Run Bash commands. Special characters does not matter.
You don't need escape anything. Example:
command = echo HACK!
EXAMPLES
An example of using baka. For example, there are two files in /etc/baka/entries/: example.org and example.com. Files content:
example.org:
local = /backups
archive = /srv/http/example.org/public
exclude = logs,cache
remote = s3://bucket/
example.com:
local = /backups
archive = /srv/http/example.com/public
copy = /srv/http/example.com/data.zip
database = mysql://myuser:password@localhost:3306/mydb
In order to start backing up these sites at different times, let's add two tasks to crontab:
00 00 * * * /usr/bin/baka backup --entry=example.com
00 00 */2 * * /usr/bin/baka backup --entry=example.org
Likewise, you can start backing up more entries by adding exceptions or specifying specific entries. For example like this:
baka backup --ignore=example.org --ignore=example.com
