bbackupquery utility -- examine store, compare files, restore, etc.

This file has markers for automatic help generation script -- '>' marks a start of a command/help topic,
and '<' marks the end of a section.

Command line:
=============

> bbackupquery [-q] [-c configfile] [commands ...]

        -q -- quiet, no information prompts
        -c -- specify another bbackupd configuation file

The commands following the options are executed, then (if there was no quit
command) an interactive mode is entered.

If a command contains a space, enclose it in quotes. Example

        bbackupquery "list testdir1" quit

to list the contents of testdir1, and then exit without interactive mode.
<

Commands:
=========

All directory names relative to a "current" directory, or from root if they
start with '/'. The initial directory is always the root directory.


> list [options] [directory-name]

        List contents of current directory, or specified directory.
        
        -r -- recursively list all files
        -d -- list deleted files/directories
        -o -- list old versions of files/directories
        -I -- don't display object ID
        -F -- don't display flags
        -t -- show file modification time
                        (and attr mod time if has the object has attributes, ~ separated)
        -s -- show file size in blocks used on server
                        (only very approximate indication of size locally)

ls can be used as an alias.
<

> ls

        Alias for 'list'. Type 'help list' for options.
<

> cd [options] <directory-name>

        Change directory
        
        -d -- consider deleted directories for traversal
        -o -- consider old versions of directories for traversal
                (this option should never be useful in a correctly formed store)
<

> pwd

        Print current directory, always root relative.
<

> lcd <local-directory-name>

        Change local directory.
        
        Type "sh ls" to list the contents.
<

> sh <shell command>

        All of the parameters after the "sh" are run as a shell command.
        
        For example, to list the contents of the location directory, type "sh ls"
<

> get <object-filename> [<local-filename>]
get -i <object-id> <local-filename>

        Gets a file from the store. Object is specified as the filename within
        the current directory, and local filename is optional. Ignores old and
        deleted files when searching the directory for the file to retrieve.
        
        To get an old or deleted file, use the -i option and select the object
        as a hex object ID (first column in listing). The local filename must
        be specified.
<

> compare -a
compare -l <location-name>
compare <store-dir-name> <local-dir-name>

        Compares the (current) data on the store with the data on the disc.
        All the data will be downloaded -- this is potentially a very long
        operation.
        
        -a -- compare all locations
        -l -- compare one backup location as specified in the configuration file.
        -c -- set return code
        -q -- quick compare. Only checks file contents against checksums,
                        doesn't do a full download
        -A -- ignore attribute differences
        -E -- ignore exclusion settings
        
        Comparing with the root directory is an error, use -a option instead.

        If -c is set, then the return code (if quit is the next command) will be
                1       Comparison was exact
                2       Differences were found
                3       An error occured
        This can be used for automated tests.
<

> restore [-d] [-r] [-i] <directory-name> <local-directory-name>

        Restores a directory to the local disc. The local directory specified
        must not exist (unless a previous restore is being restarted).

        The root cannot be restored -- restore locations individually.

        -d -- restore a deleted directory or deleted files inside
        -r -- resume an interrupted restoration
        -i -- directory name is actually an ID

        If a restore operation is interrupted for any reason, it can be restarted
        using the -r switch. Restore progress information is saved in a file at
        regular intervals during the restore operation to allow restarts. 
<

> getobject <object-id> <local-filename>

        Gets the object specified by the object id (in hex) and stores the raw
        contents in the local file specified.

        This is only useful for debugging as it does not decode files from the
        stored format, which is encrypted and compressed.
<

> usage

        Show space used on the server for this account.

        Used: Total amount of space used on the server.
        Old files: Space used by old files
        Deleted files: Space used by deleted files
        Directories: Space used by the directory structure.
        
        When Used exceeds the soft limit, the server will start to remove old and
        deleted files until the usage drops below the soft limit.
        
        After a while, you would expect to see the usage stay at just below the
        soft limit. You only need more space if the space used by old and deleted
        files is near zero.
<

> quit

        End session and exit.
