Hi!

(Sorry about asking this, but have no clue on what keyowrds I should search for)

I have a samba server on which I'm making backups to. Each backup client has a batch file on their windows system which looks similar to this (user is already logged in):

----------
set drive=Z:
set backupcmd=xcopy /s /c /d /e /h /i /r /k /y

:: START Backup
%backupcmd% "%USERPROFILE%\My Documents" "%drive%\My Documents"
----------

If i use this script to copy files from a windows drive to a windows drive it updates the creation date on the destination to the date and time of when it was copyed. In that way the script can compare source and destination and only copy files that have been modified on source since last backup.

But, when it copies over the the samba server, it keeps the date and time of creation of the file - it is not changed -, resulting in the script to copy ALL files every time the backup is initiated.

How do I tell linux (CentOS 4) to change the time&date on every file which is created in that folder?

I guess I would have to insert something into ".bash_profile" but what?

I would like to "set" the time and date in a smilar way to which you can set umask rights in a folder?

Thanks for any help!

the program touch(1) springs to mind; try investigating it to see whether or not it does what you want.

Some hours before your post i just found that "keyword" myself, after googeling for wuite some time:-)

But anyway thanks for letting me know!

Any clue on how i can tell it to automatically change all new/modified files?

No. Well, not how to do it `the GNU/Linux' way (by use of some file alteration monitor).

But, I have another idea:
1) ssh/telnet onto the linux box
2) mount the windows disk/share/...
2) cd into backup dir
3) run a makefile which copies all the data that should be backed up.

You could of course create a new user (`backup_script_01') which logs into a shell script that does that; then all you have to do is ssh.

okay, i will look into that. Not a bad idea, but i will still first check out if i can do any magic with touch..

Thanks for your reply!
