rdup-up
RDUP-UP(1) rdup RDUP-UP(1)NAME
rdup-up - update a directory tree with a rdup archive
SYNOPSIS
rdup-up [OPTION]... DIRECTORY
DESCRIPTION
With rdup-up you can update an (possibly) existing directory structure with a rdup archive.
The rdup archive has to be given to rdup-up's standard input.
Username and uids
rdup outputs both the username and uid, the receiving system (which may be a totally different system) checks if the username and uid
match. If the username and uid don't match the (numeric) uid is used on the file. The same holds true for the groupname and gid.
OPTIONS -n Do a dry-run and do not create anything on disk.
-t Create DIRECTORY (ala mkdir -p) if it does not exist.
-s N Strip N path components from a pathname. If the resulting pathname is empty after this operation it is skipped. Be careful however
with the following structure:
/foo
/foo/bar
/foo/bar/bla.txt
/foo/blork/bla.txt
With rdup-up -s2 this will leave:
<empty>
<empty>
/bla.txt
/bla.txt
And the last 'bla.txt' will overwrite the previous one, this will happen without warnings.
-r PATH
This option is related to the -s option, but works different. The string PATH is removed from (the beginning of) each pathname. With
-r /home/backup the pathname /home/backup/bin/mycmd becomes /bin/mycmd. The same could be done with -s 2, but then you need to count
the slashes. Note -s is always performed before -r.
-v Be more verbose and echo the processed files to standard output.
-vv Be even more verbose and echo processed file and the uid and gid information to standard output.
-T Show a table of contents of the rdup stream received (ala tar -tf -). With -T the directory argument is optional. -T unsets any
verbose (-v) options.
-h A short help message.
-V Show the version.
EXIT CODE
rdup-up return a zero exit code on success, otherwise 1 is returned.
