DESCRIPTION¶
bbackupquery is the main way of interacting with the backup
store from a Box Backup client machine. It supports both interactive and
batch modes of operation.
It can be used to reviewing the status of a client machine's
backup store, getting status from the store server. The main use is to
retrieve files and directories when needed.
bbackupquery supports interactive and batch modes of
operation. Interactive mode allows for interaction with the server much like
an interactive FTP client.
Batch mode is invoked by putting commands into the invocation of
bbackupquery. Example:
bbackupquery "list home-dirs" quit
Note that commands that contain spaces are enclosed in double
quotes. If the quit command is omitted, after the preceding commands
are completed, bbackupquery will enter interactive mode.
COMMANDS¶
The commands that can be used in bbackupquery are listed
below.
help
Displays the basic help message, which gives information
about the commands available in bbackupquery. Use the form help
command to get help on a specific command.
quit
End the session with the store server, and quit
bbackupquery.
cd [options] directory-name
Change directory. Options:
-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.
lcd local-directory-name
Change directory on the client machine. To list the
contents of the local directory, type sh ls (on Unix-like
machines).
list [options] [directory-name]
The list (or its synonym
ls) command lists the
content of the current, or specified, directory. The options are as follows:
-r
recursively list all files
-d
list deleted files and directories
-o
list old versions of files and directories
-I
don't display object IDs
-F
don't display flags
-t
show file modification time (and attr mod time, if the
object has attributes).
-s
show file size in blocks used on server. Note that this
is only a very approximate indication of local file size.
ls [options] [directory-name]
Synonym for list.
pwd
Print current directory, always relative to the backup
store root.
sh shell-command
Everything after the sh is passed to a shell and run. All
output from the command is displayed in the client.
Example: to list the contents of the current directory on the
client machine type sh ls.
compare -a
compare -l location-name
compare store-dir-name local-dir-name
Compare the current data in the store with the data on
the disc. Please note that all the data will be downloaded from the store, so
this can be a very lengthy process depending on the size of the store, and the
size of the part you are comparing.
Options:
-a
compare all locations.
-l
compare one backup location as specified in the
configuration file. This compares one of the top level store
directories.
-c
set return code. The return code is set to the following
values, if quit is the next command. So, if another command is run after the
compare, the return code will not refer to the compare. This option is very
useful for automating compares. Return code values:
•1 -- no differences were found
•2 -- differences were found
•3 -- an error occured
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. 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.
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. Note: This is only useful
for debugging as it does not decode files from the stored format, which is
encrypted and compressed.
restore [-d] directory-name
local-directory-name
restore -r
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.
Options:
-d
restore a deleted directory
-r
resume an interrupted restore
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.
usage [-m]
Show space used on the server for this account. Display
fields:
•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 should 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.
The -m option displays output in machine-readable
form.
BUGS¶
If you find a bug in Box Backup and you want to let us know about
it, join the mailing list[1] and send us a description of the problem
there.
To report a bug, give us at least the following information:
•The version of Box Backup you are running
•The platform you are running on (hardware and
OS), for both client and server.
•If possible attach your config files
(bbstored.conf, bbackupd.conf) to the bug report.
•Also attach any log file output that helps shed
light on the problem you are seeing.
•And last but certainly not least, a description
of what you are seeing, in as much detail as possible.
