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. +.PP + +.SH FEATURES + - easy to read ini style configuration files. + - secure, remote, incremental filesytem backup (via rdiff-backup). + incremental data is compressed. permissions are retained even + with an unprivileged backup user. + - backup of mysql databases (via mysqlhotcopy and mysqldump). + - backup of ldap databases (via slapcat and ldapsearch). + - passwords are never sent via the command line to helper programs. + - 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). + +.\" TeX users may be more comfortable with the \fB<whatever>\fP and +.\" \fI<whatever>\fP escape sequences to invoke bold face and italics, +.\" respectively. + +.SH OPTIONS +.TP +.B \-h, \-\-help +Show summary of options +.TP +.B \-d, \-\-debug +Run in debug mode, where all log messages are output to the current shell. +.TP +.B \-f, \-\-conffile FILE +Use FILE for the main configuration instead of /etc/backupninja.conf +.TP +.B \-t, \-\-test +Run in test mode, no actions are actually taken. +.TP +.B \-n, \-\-now +Perform actions now, instead of when they might be scheduled. + +.SH EXAMPLES +.TP +Backupninja can be used to impliment whatever backup strategy you choose. It is intended, however, to be used like so: +.TP +First, databases are safely copied or exported to /var/backups. Often, 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. +.TP +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 privileged. Hopefully, the remote filesystem is encrypted. +.TP +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. + +.SH SSH KEYS +.TP +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: + +.br +root@srchost# ssh-keygen -t dsa +.br +root@srchost# ssh-copy-id -i /root/.ssh/id_dsa.pub backup@desthost + +.TP +Now, you should be able to ssh from user 'root' on srchost to user 'backup' on desthost without specifying a password. + +.TP +Note: when prompted for a password by ssh-keygen, just leave it blank by hitting return. + +.SH FILES +.PD 0 +\fB/usr/sbin/backupninja\fP main script +.br +\fB/etc/backupninja.conf\fP main configuration file; general options +.br +\fB/etc/cron.d/backupninja\fP runs main script nightly +.br +\fB/etc/logrotate.d/backupninja\fP rotates backupninja.log +.br +\fB/etc/backup.d\fP directory for configuration files +.br +\fB/usr/share/backupninja\fP directory for handler scripts +.br +.PD + +.SH SEE ALSO +.BR backupninja.conf (5), +.br +.SH AUTHOR +BACKUPNINJA was written by <elijah@riseup.net>. +.br +BACKUPNINJA was packaged by <micah@riseup.net>. +.PP +This manual page was written by stefani <stefani@riseup.net>. |
