UBR, Universal Backup/Restore script.

Because I don't want to write another backup script ever again.

requisites

• Python

usage

./ubr.sh <backup|restore|config|check|check-all|download> <dir|s3|rds-snapshot> [target] [path.into.description]

configuration

All configuration goes in app.cfg, see example.cfg.

If no app.cfg is found example.cfg will be used.

Environment variables available are:

• UBR_CFG_FILE - use an alternative to app.cfg
• UBR_DESCRIPTION_DIR - where to look for descriptor files (more below)
• UBR_WORKING_DIR - root directory for temporary files during a backup (default /tmp/ubr)

The final configuration available to UBR can then be viewed with:

./ubr.sh --action config

'descriptor' files

You write a descriptor, a simple YAML file that describes targets and it does the rest.

For example:

target:
    - /var/foo/file
    - /etc/bar/file2

A backup target describes the types of paths that are listed under it. For example:

mysql-database:
    - appdb
    - appdb.users

will target your mysql database and create dumps of the databases appdb and the table users in appdb. This descriptor:

tar-gzipped:
    - /var/run/jenkins/config.xml
    - /var/run/jira/whatever.sickof.xml

will create a .tar.gz of the files specified.

Each target will have their own rules for dealing with the paths they are given.

A descriptor file can contain multiple targets but you cannot repeat targets. Only one tar-gzipped or mysql-database target per descriptor file.

tar-gzipped and files targets

These two targets are essentially the same, however the tar-gzipped target simply tars and compresses the results of calling the files target.

Everything the files target supports is also supported by tar-gzipped.

files

Creates a copy of the specified files.

Paths that are directories will be ignored. For example:

files:
    - /etc/

Won't do anything. It won't assume you want all files in that directory. You have to specify a file.

HOWEVER, the files target does support globs, so:

tar-gzipped:
    - /etc/*

would tar up and then zip all files in /etc/ (again, excluding directories).

Extended globs are also supported. For example:

tar-gzipped:
    - /etc/**

would tar up and then zip everything in /etc/. All files, all sub-directories of files, recursively.
