rsync, network shares, and soft links


Hi all,

I'm using rsync to make backups of my laptop to a windows share, and with the -l option it copies over links, but apparently does so as linux-style rather than cygwin-style.

When I do it to a local dir, the link is recognized as such and not re-sent:
$ cd test; ln -s ../apps; ll; cd ..
total 1.0K
lrwxrwxrwx 1 Ryan None 7 May 26 18:04 apps -> ../apps/

$ rsync -vrlpt test/ test-backup/
sending incremental file list
created directory test-backup
./
apps -> ../apps

$ rsync -vrlpt test/ test-backup/
sending incremental file list

$ ll test-backup/
total 1.0K
lrwxrwxrwx 1 Ryan None 7 May 26 18:04 apps -> ../apps/

However, if I target a SMB share instead, the cygwin link becomes a linux link (which never matches and is always re-sent, and which means nothing to cygwin when restored):
$ rsync -vrlpt test/ /cygdrive/z/laptop-backup/test-backup/
sending incremental file list
created directory /cygdrive/z/laptop-backup/test-backup
./
apps -> ../apps

$ rsync -vrlpt test/ /cygdrive/z/laptop-backup/test-backup/
sending incremental file list
apps -> ../apps

$ ll !$
ll /cygdrive/z/laptop-backup/test-backup/
total 1.0M
-rw-r--r-- 1 ???????? ???????? 28 May 26 18:04 apps

$ rsync -vrlpt /cygdrive/z/laptop-backup/test-backup/ test-restore/
sending incremental file list
created directory test-restore
./
apps

$ ll test-restore/apps
-rw-r--r-- 1 Ryan None 28 May 26 18:04 test-restore/apps

$ cat !$
cat test-restore/apps
!<symlink>ââ../apps

Is this a known limitation of cygwin's rsync and SMB or is there something I could have done differently?


Thanks!
Ryan
