bup meta creates, extracts, or otherwise manipulates metadata
archives. A metadata archive contains the metadata information
(timestamps, ownership, access permissions, etc.) for a set of
filesystem paths.
See bup-restore(1) for a description of the way ownership metadata
is restored.
-c, --create
: Create a metadata archive for the specified paths. Write the
archive to standard output unless --file is specified.
-t, --list
: Display information about the metadata in an archive. Read the
archive from standard input unless --file is specified.
-x, --extract
: Extract a metadata archive. Conceptually, perform --start-extract
followed by --finish-extract. Read the archive from standard input
unless --file is specified.
--start-extract
: Build a filesystem tree matching the paths stored in a metadata
archive. By itself, this command does not produce a full
restoration of the metadata. For a full restoration, this command
must be followed by a call to --finish-extract. Once this
command has finished, all of the normal files described by the
metadata will exist and be empty. Restoring the data in those
files, and then calling --finish-extract should restore the
original tree. The archive will be read from standard input
unless --file is specified.
--finish-extract
: Finish applying the metadata stored in an archive to the
filesystem. Normally, this command should follow a call to
--start-extract. The archive will be read from standard input
unless --file is specified.
--edit
: Edit metadata archives. The result will be written to standard
output unless --file is specified.
-f, --file=filename : Read the metadata archive from filename or write it to filename as appropriate. If filename is "-", then read from standard input or write to standard output.
-R, --recurse
: Recursively descend into subdirectories during --create.
--xdev, --one-file-system : don't cross filesystem boundaries -- though as with tar and rsync, the mount points themselves will still be handled.
--numeric-ids
: Apply numeric IDs (user, group, etc.) rather than names during
--extract or --finish-extract.
--symlinks
: Record symbolic link targets when creating an archive, or restore
symbolic links when extracting an archive (during --extract
or --start-extract). This option is enabled by default.
Specify --no-symlinks to disable it.
--paths
: Record pathnames when creating an archive. This option is enabled
by default. Specify --no-paths to disable it.
--set-uid=uid
: Set the metadata uid to the integer uid during --edit.
--set-gid=gid
: Set the metadata gid to the integer gid during --edit.
--set-user=user
: Set the metadata user to user during --edit.
--unset-user
: Remove the metadata user during --edit.
--set-group=group
: Set the metadata user to group during --edit.
--unset-group
: Remove the metadata group during --edit.
-v, --verbose : Be more verbose (can be used more than once).
-q, --quiet : Be quiet.
# Create a metadata archive for /etc.
$ bup meta -cRf etc.meta /etc
bup: removing leading "/" from "/etc"
# Extract the etc.meta archive (files will be empty).
$ mkdir tmp && cd tmp
$ bup meta -xf ../etc.meta
$ ls
etc
# Restore /etc completely.
$ mkdir tmp && cd tmp
$ bup meta --start-extract -f ../etc.meta
...fill in all regular file contents using some other tool...
$ bup meta --finish-extract -f ../etc.meta
# Change user/uid to root.
$ bup meta --edit --set-uid 0 --set-user root \
src.meta > dest.meta
Hard links are not handled yet.
