Re: cygwin - rsync question


Hi Steven,

Thanks for taking the time to think about this. You are correct the rsync daemon is running locally, and the network share is mounted locally, my thought (which as you say could be entirely wrong) was that the local rsync daemon doesn't seem to have the correct permissions to modify the mounted local share. Again, if I run the script locally on a local file and back it up to another drive on the local machine, everything works perfectly, it's only when I try to modify a mounted share that I get errors.

rsyncd.conf

use chroot = true
strict modes = false
log file=/cygdrive/c/Datafiles/batch_jobs/log_files/rsync.log


[backups] path = /backups comment = Dan's Offsite storage area (requires authentication) read only = false


and the command to invoke rsync in my script is as follows


BDIR9 =/cygdrive/c/data
BSERVER =localhost
ROOTBKUP =daily
EXCLUDES=/home/dan/excluded_files.txt

OPTS="-avv --no-g --no-p --chmod=ugo+rwX --modify-window=1 --delete --delete-excluded --exclude-from=$EXCLUDES --link-dest=../daily.1"

rsync $OPTS $BDIR9 $BSERVER::backups/$ROOTBKUP/daily.0

thanks again

Dan

I have a bash script that sets up a directory structure for rsync to
perform incremental backups. It all works fine locally.

I'd like to use the same approach to backup my local files to a windows
network share on a server.

I have the windows network share mounted by /etc/fstab to a directory in
my root folder. Cygwin can read and create/delete files and directories
on the mount point but when I execute an rsync command from the script
it contacts the daemon and begins to send the file list but then it fails.

Something doesn't quite make sense here. If you have the network share mounted in your local filesystem, then rsync should not be contacting a remote daemon, since both the source and destination are local. What is the command-line you are using to invoke rsync?


error is

rsync: read error: Software caused connection abort (113).

I also get a mkdir and chroot error if I try to save backup copies
within rsync.

Again, what is the rsync command-line that causes this?



it seems the rsync instance doesn't have appropriate permissions on the
mounted network share.

Is there a workaround for this ....? the way I mount the share in
/etc/fstab perhaps?

You mentioned that you *are* able to access files on the network share. So it is unlikely that rsync would be specifically denied access by some setting in your fstab. My suspicion is that you are invoking rsync incorrectly, but, unfortunately, you neglected to state your commands.


current mount looks like this:

//networkshare/backup/daily /backups smbfs user,posix=0,noacl

thanks in advance for any help.
