[mythtv-users] Hard drive failure...

Just out of curiosity, now that my system is up-and-running.  What's the
best way to back up the whole thing to a networked drive?

Do a tar or something?  Can I do it from the root (/) and get everything
(even "open" files) but excluding my /video partition and mounted samba
shares?  In Windows I'd run the system backup program, check a few boxes and
let it rip.  What do I do in Mandrake 9 / linux?

Tanks!
JC

P.S.  Here's my current mounts:
[root at p800 mythtv]# mount
/dev/hda6 on / type ext3,ext2 (rw)
none on /proc type proc (rw)    --- Don't know what this is! ;-)
none on /dev/pts type devpts (rw,mode=0620)   --- Don't know what this is!
;-)
/dev/hda5 on /video type ext2 (rw)   --- Don't want to backup this
//192.168.0.6/C on /mnt/C type smbfs (0)   --- Don't want to backup this
//192.168.0.6/DVD on /mnt/DVD type smbfs (0)  --- Don't want to backup this
//c117787-d/C on /mnt/p4_C type smbfs (0)       --- Don't want to backup
this
//192.168.0.6/V on /mnt/p4_v type smbfs (0)      --- Don't want to backup
this
//c117787-d/X_VIDEO on /mnt/p4_x type smbfs (0)  --- Don't want to backup
this
