-
-Backupninja allows you to coordinate system backup by dropping a few
-simple configuration files into /etc/backup.d/. Most programs you
-might use for making backups don't have their own configuration file
-format. Backupninja provides a centralized way to configure and
-coordinate many different backup utilities.
-
-Features:
- - easy to read ini style configuration files.
- - you can drop in scripts to handle new types of backups.
- - backup actions can be scheduled
- - you can choose when status report emails are mailed to you
- (always, on warning, on error, never).
- - console-based wizard (ninjahelper) makes it easy to create
- backup action configuration files.
- - passwords are never sent via the command line to helper programs.
- - works with Linux-Vservers (http://linux-vserver.org/)
-
-Backup types:
- - secure, remote, incremental filesytem backup (via rdiff-backup).
- incremental data is compressed. permissions are retained even
- with an unpriviledged backup user.
- - backup of mysql databases (via mysqlhotcopy and mysqldump).
- - backup of ldap databases (via slapcat and ldapsearch).
- - basic system and hardware info
- - encrypted remote backups (via duplicity).
- - backup of subversion repositories.
-
-The following options are available:
--h, --help This usage message
--d, --debug Run in debug mode, where all log messages are
- output to the current shell.
--f, --conffile FILE Use FILE for the main configuration instead
- of /etc/backupninja.conf
--t, --test Test run mode. This will test if the backup could run, without actually
- preforming any backups. For example, it will attempt to authenticate
- or test that ssh keys are set correctly.
--n, --now Perform actions now, instead of when they might be scheduled.
- No output will be created unless also run with -d.
---run FILE Runs the specified action FILE (e.g. one of the /etc/backup.d/ files).
- Also puts backupninja in debug mode.
-
-CONFIGURATION FILES
-===================
-
-The general configuration file is /etc/backupninja.conf. In this file
-you can set the log level and change the default directory locations.
-You can force a different general configuration file with "backupninja
--f /path/to/conf".
-
-To preform the actual backup, backupninja processes each configuration
-file in /etc/backup.d according to the file's suffix:
-
- .sh -- run this file as a shell script.
- .rdiff -- filesystem backup (using rdiff-backup)
- .dup -- filesystem backup (using duplicity)
- .mysql -- backup mysql databases
- .ldap -- backup ldap databases
- .pgsql -- backup PostgreSQL databases
- .sys -- general hardware, partition, and system reports.
- .svn -- backup subversion repositories
- .maildir -- incrementally backup maildirs (very specialized)
-
-Support for additional configuration types can be added by dropping
-bash scripts with the name of the suffix into /usr/share/backupninja.
-
-The configuration files are processed in alphabetical order. However,
-it is suggested that you name the config files in "sysvinit style."
-
-For example:
- 00-disabled.ldap
- 10-runthisfirst.sh
- 20-runthisnext.mysql
- 90-runthislast.rdiff
-
-Typically, you will put a '.rdiff' config file last, so that any
-database dumps you make are included in the filesystem backup.
-Configurations files with names beginning with 0 (zero) or ending with
-.disabled (preferred method) are skipped.
-
-Unless otherwise specified, the config file format is "ini style."
-
-For example:
-
- # this is a comment
-
- [fishes]
- fish = red
- fish = blue
-
- [fruit]
- apple = yes
- pear = no thanks \
- i will not have a pear.
-
-
-SCHEDULING
-==========
-
-By default, each configuration file is processed everyday at 01:00 (1
-AM). This can be changed by specifying the 'when' option in a config
-file.
-
-For example:
-
- when = sundays at 02:00
- when = 30th at 22
- when = 30 at 22:00
- when = everyday at 01 <-- the default
- when = Tuesday at 05:00
-
-A configuration file will be processed at the time(s) specified by the
-"when" option. If multiple "when" options are present, then they all
-apply. If two configurations files are scheduled to run in the same
-hour, then we fall back on the alphabetical ordering specified above.
-If two configurations files are scheduled close to one another in
-time, it is possible to have multiple copies of backupninja running if
-the first instance is not finished before the next one starts.
-
-Make sure that you put the "when" option before any sections in your
-configuration file.
-
-These values for 'when' are equivalent:
-
- when = tuesday at 05:30
- when = TUESDAYS at 05
-
-These values for 'when' are invalid:
-
- when = tuesday at 2am
- when = tuesday at 2
- when = tues at 02
-
-
-REAL WORLD USAGE
-================
-
-Backupninja can be used to implement whatever backup strategy you
-choose. It is intended, however, to be used like so:
-
-(1) First, databases are safely copied or exported to /var/backups.
- Typically, you cannot make a file backup of a database while it
- is in use, hence the need to use special tools to make a safe copy
- or export into /var/backups.
-
-(2) Then, vital parts of the file system, including /var/backups, are
- nightly pushed to a remote, off-site, hard disk (using
- rdiff-backup). The local user is root, but the remote user is not
- priviledged. Hopefully, the remote filesystem is encrypted.
-
-There are many different backup strategies out there, including "pull
-style", magnetic tape, rsync + hard links, etc. We believe that the
-strategy outlined above is the way to go because: (1) hard disks are
-very cheap these days, (2) pull style backups are no good, because then
-the backup server must have root on the production server, and (3)
-rdiff-backup is more space efficient and featureful than using rsync +
-hard links.
-
-
-SSH KEYS
-========
-
-In order for rdiff-backup to sync files over ssh unattended, you must
-create ssh keys on the source server and copy the public key to the
-remote user's authorized keys file. For example:
-
- root@srchost# ssh-keygen -t dsa
- root@srchost# ssh-copy-id -i /root/.ssh/id_dsa.pub backup@desthost
-
-Now, you should be able to ssh from user 'root' on srchost to
-user 'backup' on desthost without specifying a password.
-
-Note: when prompted for a password by ssh-keygen, just leave it
-blank by hitting return.
-
-The included helper program "ninjahelper" will walk you through creating
-an rdiff-backup configuration, and will set up the ssh keys for you.
-
-INSTALLATION
-============
-
-Requirements:
- apt-get install bash gawk
-
-Recommended:
- apt-get install rdiff-backup gzip hwinfo
-
-Files:
- /usr/sbin/backupninja -- main script
- /etc/cron.d/backupninja -- runs main script nightly
- /etc/logrotate.d/backupninja -- rotates backupninja.log
- /etc/backup.d/ -- directory for configuration files
- /etc/backupninja.conf -- general options
- /usr/share/backupninja -- handler scripts which do the actual work
-
-Installation:
- There is no install script, but you just need to move files to the
- correct locations. All files should be owned by root.
-
- # tar xvzf backupninja.tar.gz
- # cd backupninja
- # mv backupninja /usr/sbin/backupninja
- # mv ninjahelper /usr/sbin/ninjahelper
- # mv etc/logrotate.d/backupninja /etc/logrotate.d/backupninja
- # mv etc/cron.d/backupninja /etc/cron.d/backupninja
- # mkdir /etc/backup.d/
- # mv etc/backupninja.conf /etc/backupninja.conf
- # mv handlers /usr/share/backupninja
-
-
-VSERVERS
-========
-
-If you are using Linux-Vservers (http://linux-vserver.org/) there are some
-special capabilities that different handlers have to make vserver backups easier.
-Set the variable "vservers" to be "yes" in /etc/backupninja.conf and see the
-example configuration files for each handler to configure the vserver specific
-variables.
-
-Additional vserver variables that can be configured in /etc/backupninja.conf. but
-probably don't need to be changed:
-
-VSERVERINFO (default: /usr/sbin/vserver-info)
-VSERVER (default: /usr/sbin/vserver)
-VROOTDIR (default: `$VSERVERINFO info SYSINFO |grep vserver-Rootdir | awk '{print $2}'`)
-
-NINJAHELPER
-===========
-
-Ninjahelper is an additional script which will walk you through the process of
-configuring backupninja. Ninjahelper has a menu driven curses based interface
-(using dialog).
-
-To add an additional 'wizard' to ninjahelper, follow these steps:
-
-(1) to add a helper for the handler "blue", create the file
- blue.helper in the directory where the handlers live.
- (ie /usr/share/backupninja).
-
-(2) next, you need to add your helper to the global HELPERS variable
- and define the main function for your helper (the function name
- is always <helper>_wizard). for example, blue.helper:
- HELPERS="$HELPERS blue:description_of_this_helper"
- blue_wizard() {
- ... do work here ...
- }
-
-(3) check the examples of the included helpers to see how they are
- written. The dialog functions are defined in easydialog.sh.
