MRB(8) System Manager's Manual MRB(8) NAME
mrb - manage incremental snapshots with rsync/make. SYNOPSIS
mrb command DESCRIPTION
mrb is a simple aid to creating efficient incremental snapshots of a set, or sets, of directories whenever that may be required. It may be used as part of a regular automated backup regime, or for manually checkpointing changes at convenient points in time. COMMANDS
The following commands are recognised (where 'MODULE' is the name of one of your snapshot definitions): new-MODULE Create a skeleton definition for a new snapshot 'MODULE'. dest-MODULE Create the destination dir for 'MODULE'. This directory must exist to create a snapshot. snap-MODULE Create a snapshot of 'MODULE'. sync Create snapshots of all defined modules. If run as root this may be configured to include the modules of other users too (see MRB_SYNC_USERS in ~/.mrb/defaults). help Show mrb's own help text. CONFIGURATION FILES
Per-user configuration The following files may be used to specify global and local configuration options. /etc/default/mrb system default configuration. ~/.mrb/defaults per-user configuration. Per-user options The following options control behaviour for all of a user's modules. MRB_SNAPSHOT_LOG An optional file path where transfer details will be recorded. If unset these details will not be logged. MRB_SYNC_USERS A space separated list of users whose modules should be included in a sync. This is mostly only useful for root, as mrb will assume the identity of each user before creating snapshots of their modules. If unset, only the invoking user's modules will be sync'ed. MRB_CONFDIR An space separated list of the directories to search for module definition (*.mrc) files. They will be searched in the order given, with new modules added by default to the last one listed. There should be few reasons to change the default value. Per-module configuration The default MRB_CONFDIR value will search for module definitions in: /etc/mrb/*.mrc ~/.mrb/*.mrc Those created by new-MODULE will be placed in this latter location by default. Per-module options In each case module below is the name of the particular module that the value set should apply to. These options should be defined in a file named module.mrc. module_SRC A space separated list of the files and (top level) directories to include in the snapshots for this module. module_DEST The directory root where snapshots of module should be stored. module_INCLUDE An optional list of rsync(1) include patterns. module_EXCLUDE An optional list of rsync(1) exclude patterns. module_FILTER An optional list of rsync(1) filter patterns. module_FILTER_FILE An optional filename for rsync(1) dir-merge filtering support. module_RSYNC_OPTIONS Optional additional rsync(1) options to pass verbatim when it is invoked. module_PRECOMMAND An optional shell command to invoke just prior to creating a new snapshot. If the command does not return a successful exit status, then the snapshot creation will be aborted before it begins. It may be used to mount removable media or similar. module_POSTCOMMAND An optional shell command to execute after making the snapshot. It will not be called if the snaphot creation failed at an earlier stage, and its return status may halt a sync operation if it fails with more modules still to process. It may be used, for example, to unmount removable media again. module_USER An optional user name to check that mrb is running as before performing a snapshot. This can be used to ensure you have the correct permisson to access the files being mirrored before you get too far. SEE ALSO
