BBACKUPQUERY(8) Box Backup BBACKUPQUERY(8)NAMEbbackupquery - Box Backup store query and file retrieval
SYNOPSISbbackupquery [-q] [-c configfile] [command ...]
DESCRIPTIONbbackupquery 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.
OPTIONS-q
Quiet. Suppresses status output while running.
-c configfile
Use configfile instead of the default bbackupd.conf file. Can be a
relative or full path.
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.
