About permissions...: It may not be so easy to tell.. here is what a ls -l on a NSFS (winXP) mounted from gentoo looks like: -rwxrwSrwt 1 root root258 Oct 28 22:11 cdiag.txt cdiag.txt is a simple text file. I don't get an error here but when next mounted the permission I set with chmod have disappeared and -rwxrwSrwt is back Neither NSFS or fat32 support unix like permissions... not sure why I get no error maybe cifs mount suppresses them. About the symlink issue notice the similar output I get when attempting to rsync symlinks to an NSFS file system: Note too that mounted winXP fs does not support symlinks in unix fashion. Nor does it support unix like permissisons.

There are various ways to handle this investigate the different symlink flags in man rsync.

It can be done if the winbox has SFU (Services for Unix) installed I've heard, but really isn't the problem that the receiving fs does not support them? note or anyone interested: (Services for Unix is a free package from MS). -- gentoo-user@gentoo.org mailing list

You say the fs was created by the the router and that you don't know what the fs is. Yet you also say it has nothing to do with windows. Your error output indicates it is almost certainly a windows based fs. Can you post the output of fdisk -l /dev/YourUSBdevice (minus the last number) (You'll need to su to root for this) You will need to plug the device directly into the gentoo box and figure out which sdX device it is then: fdisk -l /dev/sdX > 1.

How do other gentoo'ers > achieve backup onto a windows machine? There are other gotchas that are even worse using windows based receiver fs. Some kind of file modification date snafu can cause massive re rsyncing of everything in the backup. It happend to me quite a while back so I've forgotten the details.

Plug the USB devices into you gentoo box usb ports then: Reformat it to ext3 or some other linux friendly fs. Use fdisk or cfdisk to set up any partitions you might want use mkfs.ext3 or mfks.reiserfs (or some other favored fs) while device is umounted.

Those error messages about symlinks would indicate otherwise. Unless the error is comming from cifs which is possible sincy it does not support symlinks.

As I feared the er.log was not all that helpfull but again it appears to me the fs is not allowing `chown' to run. More evidence the receiving fs does not support it. I don't really understand the relationship between what you call a server and the actual disks. How is it different from just having the disks on an USB port? Is it possible to connect these disks direct to your gentoo box? If so you will be able to identify them beyond any doubt. Further, you will be able to mount them under there native format type instead of cifs if they are ext3 and attempt the rsync in that setup to learn if cifs is the problem here. Once connected to you gentoo box an `fdisk -l' as root will show what filesystem is on them. I suggest you take this question in as succinct a format as you can to the rsync list. I suspect some of the experts there will recognize this right off the bat. It can be accessed thru gmane. http://www.gmane.org Or if you use a newsreader it can be accessed at `news.gmane.org' The newgroup you're after is: gmane.network.rsync.general When you first post to it, you will get back a message from gmane you'll need to reply to so your post will get put on the group.

Hello Harry, Thanks for your response. I am mounting the network usb drive using cifs The network storage unit is a LINKSYS Network Storage Link for USB 2.0 Disk Drives. I don't know what file system is used but the discs had to be formatted by the linksys setup program. I have just looked at some files on the backup disc and the owner and permissions seem to be intact. This is the error when copying the Mail directory mkstemp "/mnt/network/home/paul/Mail/Gimp/cur/.1133608028.9158.nxwHc:2,S.CDg1dQ" failed: Not a directory I'm sure I'm doing something stupid Paul -- This message has been sent using kmail with gentoo linux -- gentoo-user@gentoo.org mailing list

Harry, This problem has nothing to do with windows, in fact my XP machine isn't even switched on. This is the ls -l on /mnt/network drwxrwxrwx 1 root root 0 Mar 9 14:03 usr I saw the info about coping the actual file instead of the symlink in man rsync. This raises a couple of questions. 1. If I copy the actual file and in the future need to restore my system from this full backup, what will be the implication of having perhaps multiple copies of some files? 2. How do other gentoo'ers achieve backup onto a windows machine? I will change the command line to include another -v and an STDERR to see if this helps with the mail problem. I have noticed that some messages get copied - in the case of one of my mail folders I have951 messages but only 15 are in the backup, some folders are completely empty. I am a little confused if cifs does or does not support symlinks. As a last resort is there any other way for me to to achieve a complete copy of my gentoo system on this network usb storage link?

The external USB discs have a USB connector that plugs into the Linksys network storage box, that in turn is connected to my network switch as are my linux and my windows boxes.

I really want to have these discs networked so that both contents are available to both machines. So Question: What is the best method of copying files via the network and How should I mount the discs for error free operation?
