Rsync - Preserve owner/group with different UID/GID
Dear Folks :-)

I want to rsync some files between some servers and preserve files owner and group (not UID or GID), in some machines UID and GID are differents, for example:

a) In the rsync server:

Code:
# stat vbseo.php 
  File: `vbseo.php'
  Size: 26758           Blocks: 56         IO Block: 4096   regular file
Device: 804h/2052d      Inode: 21971712    Links: 1
Access: (0644/-rw-r--r--)  Uid: (10002/ user1)   Gid: (10001/  psacln)
Access: 2006-10-09 18:30:59.000000000 +0200
Modify: 2006-10-09 19:12:48.000000000 +0200
Change: 2006-10-09 19:12:48.000000000 +0200

# grep psacln /etc/group
psacln:x:10001:

b) In the rsync clients:

Code:
# stat vbseo.php 
  File: `vbseo.php'
  Size: 26758           Blocks: 56         IO Block: 4096   regular file
Device: 803h/2051d      Inode: 37421492    Links: 1
Access: (0644/-rw-r--r--)  Uid: (10002/ user1)   Gid: (10001/ UNKNOWN)
Access: 2007-11-30 10:46:59.000000000 +0100
Modify: 2006-10-09 19:12:48.000000000 +0200
Change: 2007-11-30 10:46:59.000000000 +0100

# grep psacln /etc/group
psacln:x:2524:

In the case of UID/GID are the same between machines there isn't problems.. but when don't match there are problems. I have tried several rsync options like "--owner", "--group", "--numeric-ids", "--super", etc.. but getting the same result.. is there anyway to make this with rsync?

I have a similar solution with tar+ssh but I want to use Rsync:

Code:
tar cpzf - /source --ignore-failed-read --ignore-zeros | ssh root@192.168.x.x -p22 "cd /destination; tar --same-owner -xzf -"

Regards,

gdcmpdf

gdcmpdf(1)							       GDCM								gdcmpdf(1)

NAME

       gdcmpdf - Tool to convert PDF to PDF/DICOM.

SYNOPSIS

       gdcmpdf [options] file-in file-out

DESCRIPTION

       The gdcmpdf tool convert a PDF file (any PDF version) into an encapsulated PDF/DICOM file. By default it will try to read the PDF meta
       information stored in the PDF and convert this information to some specific DICOM fields (see below). However it may fails (eg. wrong
       password on encrypted PDF file) in which case empty value are used.

PARAMETERS

       file-in	 PDF input filename

       file-out  DICOM output filename

options
   general options
	 -h   --help
		print this help text and exit

	 -v   --version
		print version information and exit

	 -V   --verbose
		verbose mode (warning+error).

	 -W   --warning
		warning mode, print warning information

	 -E   --error
		error mode, print error information

	 -D   --debug
		debug mode, print debug information

Usage Example
       $ wget http://gdcm.sourceforge.net/gdcm.pdf
       $ gdcmpdf gdcm.pdf gdcm.dcm

       To re-extract the encapsulated pdf file:

	$ gdcmraw -i gdcm.dcm -t 42,11 -o gdcm.dcm.pdf
	$ diff gdcm.pdf gdcm.dcm.pdf

PDF Info Mapping
       Here is how the PDF info is mapped to DICOM information (typical pdfinfo output):

       Title:	       GDCM Reference Manual
       Subject:        Grassroots DICOM API reference
       Keywords:       GDCM,DICOM,JPEG,Lossless JPEG,JPEG-LS,J2K,JPEG 2000,RLE

       File size:      13756841 bytes
       Optimized:      yes
       PDF version:    1.4

       Converted to DICOM this leads to:

       o Acquisition Date Time is set to the Modify Time of the actual pdf file,
       o Content Date/Time are set from the actual PDF header info: CreationDate.
