Sure, that's easy! There's 2 ways to do it.

One way, the way I'd do it - Make the folder where you want the files on the windows pc shared and writeable. Make a script on the linux box that mounts the share, copies the files to it, then unmounts it:

mount -t cifs // -o username=myusername,password=mypassword /mnt/whatever/
cp /my/path/files.* /mnt/whatever
umount /mnt/whatever

Add this script to cron, and it will run whenever it's scheduled. Some distros have /etc/cron.daily, /etc/cron.weekly, /etc/cron.monthly etc. folders, and you can just put the script in whatever directory is appropriate (and dont forget to chmod it to be executable).

The other way would be to set up a samba share on the linux box, and make the windows pc map the drive, and copy whatever files it wants. IDK how to schedule a job on a windows PC, but it's basically the same concept, just making the windows PC do the work instead of the linux box.

As Suprstar suggests, having a shared, writeable folder on the Windows machine and mounting it through a script is the simplest way of doing it. There are a few things you need to consider if it is to be an automated operation....

First, it seems that mount sometimes takes a little while to settle, and attempting to write to the mounted share before it has settled will cause problems. Second, in an automated system, I would want a bit of error checking, and some way to tell if things have gone wrong.

This is adapted from a script I use to backup an SME server system to a Samba share:

mount -t cifs - user=synbak%Synbak1 // /mnt/backup
sleep 4 #allow the mount to stabalize before attempting to write to it
if [ -d /mnt/backup/box1 ]; then
     cp /home/notme/* /mnt/backup/box1
     sleep 20 #make sure any cached data has been written to the share
     umount /mnt/backup
     # Generate a log entry if the mount failed
     echo "`date +%m+%d-%R` Mount failed, backup aborted" >> /var/log/backup.log
Using the -d test, I check fo the existance of a directory on the share (which checks that the mount command has worked), then go on with the copy. If the mount failed, I get a log entry that reminds me to check what went wrong. If the system is set up for it, an email message could be used instead of a log.

One other thing you need to consider is the type of files you are copying. If it is just data files, it probably doesn't matter. But, if you are backing up something like your home directory, you need to remember that copying files to a Windows share will not preserve the owner and permissions data that Linux uses. Under those circumstances, you would be better using something like tar (with optional compression) rather than copying. Tar will allow you to preseve the permissions and ownership data, which will prevent problems if you need to copy the files back.

In that instance, you could use something like this in place of the copy command:

tar czvpf /mnt/backup/box1/backup.tar.gz .
There are lots of other options, but that should give you some starting points.

Welcome to LQ,

If you have any issue start a new thread. You have hijacked other's thread.

Press <ALT>+F2 then run the command gnome-terminal on the run prompt which opens terminal.
