Hey all. I know _one_ of these OSes isn't exactly appropriate for the
group, but also that it's likely some of you have done exactly the same
thing.

Here's the scenario-
Linux SMP server running NFS and samba for filesharing and backups.
Dual boot laptop running Gentoo/Linux and XP. (actually and RH7.3, but
irrelevant here..)
Laptop is configured with XP on NTFS but all data is mounted from a vfat
partition, allowing data sharing when booted into Linux.

What I'd like to do is a standard backup of the 'win data disk'
periodically to the Linux server. eg first a full backup, then
incrementals as desired. Tar and gzip/bzip2 should be ideal here, at
least in the fact they can handle the incremental, and I'd _really_ like
to avoid any use of the M$ backup tools, as some of the data being
backed up includes source code for C, C++ and java that's
cross-platform- in other words, I do potentially have the need to
restore this data to a linux native partition on the server, or on
another networked box occasionally.

So, the question becomes these:
1. I do run Cygwin on the Windows installation- anyone know if it's
100% compatible with standard GNU tar, or any gotchas involved in just
using Cygwin tar for backups of this data?

2. I'm running a pretty full install of the Cygwin tools, but AFAIK,
you need to be running a Cygwin shell to use many/all of the tools, eg
cron for incrementals- any decent solution to this one, not requiring a
bash window be up at all times?

3. Any better ideas out there? Best I'm conign up with offhand is
along the lines of figuring out Windows Scheduling, which I believe
finally exists(sorry, I'm a Unix developer/admin, can't stand Win but
have to have it on this system..), and having it call a shell script
under Cygwin.

Thanks in Advance,

Scott
