zabbixbackup 0.0.1b4

Zabbix database backup utility for postgres and mysql

Zabbix backup python script

EXPERIMENTAL: use at your own risk!

Python script to perform zabbix dumps.

Inspired by the project https://github.com/npotorino/zabbix-backup.

Install

pip install zabbixbackup

Examples

Create a backup connecting as user postgres to the db zabbix with schema zabbix

python -m zabbixbackup psql --host 127.0.0.1 --user postgres --passwd mypassword --database zabbix --schema zabbix

Create a tar archive dump and save standard zabbix configuration files along with it.

python -m zabbixbackup psql --host 127.0.0.1 --passwd mypassword --format tar --save-files

Create a "custom" archive and save it to a backup folder, rotate backups to retain only the last four.

python -m zabbixbackup psql --host 127.0.0.1 --passwd mypassword --format custom --rotate 4

Setup an authentication (.pgpass) file and use it to login in subsequent call.

python -m zabbixbackup pgsql --host 127.0.0.1 \
          --passwd - --keep-login-file --dry-run
[input password]
mv .pgpass /root

python -m zabbixbackup pgsql --host 127.0.0.1 --login-file /root/.pgpass

Setup an authentication (mylogin.cnf) file and use it to login in subsequent call.

python -m zabbixbackup mysql --host 127.0.0.1 \
          --passwd - --keep-login-file --dry-run
[input password]
mv mylogin.cnf /root

python -m zabbixbackup mysql --host 127.0.0.1 --login-file /root/mylogin.cnf

Database engine

<DBMS>

Default: no default (mandatory)

Database engine to use. Either postgresql or mysql (mariasql compatible).

Read zabbix configuration

--read-zabbix-config, -z

Default: False

Try to read database host and credentials from Zabbix config. The file is read and parsed trying to collect as much as possible. Every variable collected will be used if not already provided by user arguments.

Implicit if --zabbix-config is set.

Zabbix configuration file

--zabbix-config ZBX_CONFIG, -Z ZBX_CONFIG

Default: /etc/zabbix/zabbix_server.conf

Zabbix configuration file path.

Read MySQL configuration (MySQL specific)

--read-mysql-config, -c

Default: False

Read database host and credentials from MySQL config file. Implicit if --mysql-config is set.

MySQL configuration file (MySQL specific)

--mysql-config MYSQL_CONFIG, -C MYSQL_CONFIG

Default: /etc/mysql/my.cnf

MySQL configuration file path. Implicit if --read-mysql-config is set.

Dry run

--dry-run, -D

Default: False

Do not create the actual backup, only show dump commands. Be aware that the database will be queried for tables selection and temporary folders and files will be created. This is meant only for inspection and debugging.

Hostname (special for Postgres)

--host, -H

Default: 127.0.0.1

Hostname/IP of DBMS server, to specify a blank value pass '-'.

For postgresql special rules might apply (see Postgres psql and pg_dump online documentation for sockets).

Port

--port PORT, -P PORT

Default: 5432 for Postgres, 3306 for MySQL)

Database connection port.

Socket (Mysql specific)

--socket SOCK, -S SOCK

Default: None

Path to MySQL socket file. Alternative to specifying host.

Username

--user USER, -u USER

Default: zabbix

Username to use for the database connection.

Password

--passwd PASSWD, -p PASSWD

Default: None

Database login password. Specify '-' for an interactive prompt. For Postgres, a .pgpass will be created to connect to the database and then deleted (might be saved with the backup).

Keep login file

--keep-login-file

Default: False

Do not delete login file (either .pgpass or mylogin.cnf) on program exit.

Useful to create the login file and avoid clear password or interactive prompt.

Login file

--login-file LOGINFILE

Default: None

Use this file (either .pgpass or mylogin.cnf) for the authentication.

Database name

--database DBNAME, -d DBNAME

Default: zabbix

The name of the database to connect to.

Database schema (Postgres specific)

--schema SCHEMA, -s SCHEMA

Default: public

The name of the schema to use.

Reverse lookup

--reverse-lookup, -n

Default: True

(NOT IMPLEMENTED) Perform a reverse lookup of the IP address for the host.

Unknown tables action

--unknown-action {dump,nodata,ignore,fail}, -U {dump,nodata,ignore,fail}

Default: ignore

Action for unknown tables.

Choose dump to dump the tables fully with definitions. nodata will include only the definitions. ignore will skip the unknown tables. fail will abort the backup in case of an unknown table.

Monitoring tables action

--monitoring-action {dump,nodata}, -U {dump,nodata}

Default: nodata

Action for monitoring table.

Choose dump do dump the tables fully with definitions. nodata will include only the definitions.

Add columns

--add-columns, -N

Default: False

Add column names in INSERT clauses and quote them as needed.

Save configuration files

--save-files

Default: True

Save folders and other files in the backup (see --files).

File index to save with the backup

--files FILES

Default: '-'

Save folders and other files as listed in this index file. Non existant will be ignored. Directory structure is replicated (copied via cp).

File format: one line per folder or file.

If FILES is - then the standard files are selected, i.e: /etc/zabbix/ and /usr/lib/zabbix/.

Postgres dump compression

--compression COMPRESSION

Default: None

Passed as-is to pg_dump --compress, might be implied by format.

Available formats: plain, custom, directory, or tar (see postgres documentation).

Backup archive format

--archive ARCHIVE, -a ARCHIVE

Available formats are xz, gzip and bzip2. Use :<LEVEL> to set a compression level. I.e. --archive xz:6.

Output directory

--outdir OUTDIR, -o OUTDIR

Default: '.'

The destination directory to save the backup to.

Backup rotation

--rotate ROTATE, -r ROTATE

Default: '0'

Rotate backups while keeping up 'R' old backups. Uses filenames to find old backups. 0 = keep everything.

Verbosity

--quiet, -q

--verbose, -v

--very-verbose, -V

--debug

Default: verbose

Don't print anything except unrecoverable errors (quiet), print informations only (verbose), print even more informations (very verbose), print everything (debug).
