-C, --create [<path>/]<database>
creates an empty database that will collect information about several archives. The
<database> is a filename that is required for -B option. To destroy a <database> just
remove the file.
-B, --base [<path>/]<database>
specify the database to read or modify. The <database> file must exist, and have a
database structure (see -C option).
-i, --interactive use a keyboard interactive text menu to do operations on the given database. So you
may avoid reading the other options described in this manual page, if you wish, and
just use the interactive option. You will however always have to create an empty
database (-C option) and restore files manually (-r option).
-A, --add [<path>/]<basename> [ [<path>/]<archive_basename>]
add an archive to the database. An isolated catalogue can also be used only if it has
been produced by dar version 1.2.0 or above. Why ? Because, an isolated catalogue
produced by older version will always tell that no files are saved in the archive of
reference, in that case the solution is to provide the archive itself as argument. An
optional second argument is the basename of the archive if it is different from the
first argument (need for extraction of files). For example you could have an isolated
catalogue in first argument and the basename of the original archive (where is stored
the data) as second argument. By default,
-9, --min-digits <num>
the slice number zeroed padding to use to get the slices filename (for more details
see dar man page at this same option) dar_manager will look for an archive of
reference in the command line used to create each archive, but in some cases, it may
be necessary to specify the archive name (for example if you've changed its name).
-l, --list displays the information about the archives compiled in the database. In particular,
a number is given to each archive, which is required to some other option to design a
particular archive within the database. Nothing avoids you to feed the database with
several archive of the same basename ! You will just have to guess which one is asked
under this name. :-)
-D, --delete <number>[-<number>]
removes an archive (or a range of archive) from the database. The number of the
archive (or the min and max number or the archive range) is correspond to those given
by the -l option. Note that all archive number greater than the one(s) to be delete
will be decremented to keep continuous numbering of the archive inside the database.
If a single number is given (not a range), it may be also a negative number, by which
it means counting from the end. For example, -1 means the last archive of the base,
-2 the penultimate, etc.
-b, --basename <number> <new_archive_basename>
this option allows you to rename the archive basename (used when restoring files from
it). Here too, the number may be also a negative number.
-p, --path <number> <path>
this option allows you to change the location of a given archive (used when restoring
files from it). Here too, a negative number is allowed.
-o, --options [list of option to pass to dar]
Specify the option to use when calling dar. Each call erases the previous setting.
Possible dar options are all the available ones except "-x" and simple arguments
(the [list of path]) which will be added by dar_manager itself.
-d, --dar [<path>] Set the path to dar. If no argument is given, dar is expected to be located in the
PATH
-r, --restore [list of files or directories to restore]
dar_manager will restore all (an only) the given files or directories, in their
latest recorded status, or before the date give thanks to the -e option. If a
directory is given all subfiles and subdirectories are restored recursively in it.
You can filter out some files from this recursion thanks to dar usual filtering
option (see dar man page) you can provide beside -r using the -e option (see below).
Dar_manager lead dar to remove any file, if a file is stored as having been removed
at date requested for restoration, it is simply not restored. Thus if you restore in
an empty directory you will get all the files and directories you provided to
dar_manager in the state they have at the date you asked. File that did not existed
at that time will not be restored. However you can restore over an existing
installation, dar will then warn you before overwriting files (see -w and -n options
for dar) but will still not remove files that were recorded removed from a previous
archive of reference. Note that files listed after -r option, must never have an
absolute path. They will be restored under the directory specified with -R option of
dar (passed to dar using -o or -e options), or by default, under the current
directory.
-w, --when <date> alters the -r option behavior: still restores the files in the most recent version
available but only before the given date (versions of more recent dates are ignored).
The <date> must respect the following format [ [
[year/]month/]day-]hour:minute[:second]. For example "22:10" for 10 PM past 10 or the
current day, "7-22:10" for 10 PM past 10 the 7th of the current month, "3/07-22:10"
for the 7th of march at 22:10 of the current year, "2002/03/31-14:00:00" the date of
the first dar's release ;-). The given date must be in the past, of course, and is
compared to the "last modification" date of the saved files and not to the date at
which archives have been done. Thus if a file has been changed long ago but saved in
a recent (full) archive, it will be elected for restoration even for dates older than
the creation of the archive. In the other way, a file saved long time ago with a
mtime that was set to a date in the future will not be elected for restoration when
giving the date at which was done the archive.
Note that the provided date is relative to the system timezone which is overriden if the TZ
environement variable is set (see tzselect(1) for more details)
-e, --extra <options>
pass some more options to dar. While the -o options takes all that follows on the
command line as argument to pass to dar and write these in the database, the -e
option does not alter the database and has only one argument. In other words, if you
need to pass several options to dar through the use of the -e option, you need to use
quotes (simple quotes ' or double quotes ") to enclose these options. Example:
dar_manager -B database.dmd -e "-w -v -p -b -r -H 1" -r some/files
while using -o option you must not use quotes:
dar_manager -B database.dmd -o -w -v -p -b -r -H 1
-u, --used <number> list the files that the given archive owns as last version available. Thus when no
file is listed, the given archive is no more useful in database, and can be removed
safely (-D option). If <number> is zero, all available file are listed, the status
provided for each file present in the database is the most recent status. A negative
number is allowed for this option (see -D option for details).
-f, --file <file> displays in which archive the given file is saved, and what are the modification date
(mtime) and change date (ctime).
-s, --stats show the number of most recent files by archive. This helps to determine which
archive can be safely removed from the database.
-m, --move <number> <number>
changes the order of archives in the database. The first number is the number of the
archive to move, while the second is the place where it must be shifted to.
Archive order is important: An old archive must have a smaller index than a recent
archive. If you add archive to a database in the order they have been created all
should be fine. Else if a file has a more recent version in an archive which index is
smaller, a warning will be issued (unless -ai option is used). This can occur if by
mistake you added an archive to the database in the wrong order (old archive added
after a recent one), in that case simply using the -m option will let you fix this
mistake. If instead the problem is relative to a single file (or a small set of
file), you should wonder why this file has its modification date altered in a way
that it pretends to be older than its really is. Checking for the signs of a rootkit
may be a good idea.
-c, --check check the database consistency, in particular the date ordering is verified and
warning are issued for each file having more recent version located in an archive
with a smaller index inside the database. -ai option makes -c option useless.
-N, --ignore-options-in-base
Do not use the options stored in database when calling dar for restoration. This
option is only useful while restoring files from dar_manager, either directly (-r
option) or using a batch file (-@ option, see below).
-k, --ignore-when-removed
By default, dar_manager does not ask dar to restore file that have been removed at
the requested date (or in the latest state available). This is useful for example to
restore a directory in the state it has at a given date (only files that existed at
that time are restored). However when you want to restore a file that has been
destroyed by accident, you need to use -k option so you don't have to determine at
which date that file existed to be be able to ask dar_manager to restore that file in
the state it had before that date. In other words, -k option gives a behavior of
dar_manager backward compatible with dar_manager released beside version 2.3.x of
dar.
-ai, --alter=ignore-order
avoid dar_manager to issue a warning for each file not following a chronological
order of modification date when the archive number in the database is growing.
-@, --batch <filename>
allows you to do several operations on a given database. All operations are defined
in the provided <filename> and refer to the same database as defined by the -B switch
on command line. This batch file, must thus not contain neither -B, -C, -i or -ai
option (-ai are global to the batch operation). The batch file expected layout is one
command per line, thus several arguments (like -l -v for example) may take place on a
given line of the file (-v can be found both on command line for verbose output about
the batch operation steps, as well as inside the batch file for verbose output of a
particular batched command). Arguments are separated by spaces or tabs, other
characters are passed as-is. In consequence, you should only need to use quotes
(using " or ') if you intend to use an argument containing space. Last, comments may
be placed on any line beginning by a hash character (#).
-z, --compression <algo>[:<level>]
Available creating or modifying a database content (-C, -A, -D, -m, -i, -L options),
this option let you set the compression algorithm and eventually the compression
level to use when the database is wrote to file. By default gzip:9 is use, but you
can use "none" for no compression, "bzip2", "xz" and "lzo" and other compression
algorithms (see -z option in dar's man page for an up to date list of available
algorithms). Note: this option is only needed if you want to *change* the compression
algorithm or level. Once defined, either at database creation time using -C option,
or modified afterward, the compression scheme is stored in the database header and
used for writing down database back to file.
-Q Do not display any message on stderr when not launched from a terminal (for example
when launched from an at job or crontab). Remains that any question to the user will
be assumed a 'no' answer, which most of the time will abort the program.
-v, --verbose displays additional information about what it is doing.
-h, --help display help usage
-V, --version display software version
