I need to ensure backup of some important files on some workstations. Now it's done buy user starting a .bat file which copies his local files to network location where dayly backups are implemented. Is there a good way to establish these backups, thinking that files they copy somtimes go up to 2GB (these are outlook .pst files and users just don't want to clear them up, but do need an uptodate backup of their mail). May be there is a tool which will allow to make incremetual backup instead of overwriting large files everytime?

You don't need an additional tool for that. You can use your existing batch file to do incremental bakcups.

Here is the batch file I use for that very purpose. (Except I backup from one networked drive to another.)

d:
cd N-Drive
xcopy n:\*.dwg/s/d
xcopy n:\*.xls/s/d
cd..
cd P-Drive
xcopy p:\*.*/s/d
cd..
c:
echo off
echo .
echo .
echo .
echo .
echo .... "Backup of N-Drive and P-Drive completed" ....
echo .
echo .
echo .
echo .
pause

Of course, you'd have to cahnge it accordingly depending on you backup source and destination.

The line:

xcopy n:\*.dwg/s/d

includes the switches /s and /d. The /s will copy subdirectories, and the /d will copy incrementally, that is oly files that have been added or changed since the last backup.

Feel free to emai me if you have any questions.

good luck,

Thanks, but the script you show is actually the same kind I'm using right now. The problem is - I have to back up same file that's rather large and renewed every time you open MS Outlook regardless weather you change anything. So I wanted to get some ideas of special kind of tool or something. Thanks anyway.
