IIUC, you 'just' need a backup of your system. I'd recommend to rsync
your data to your backup like

rsync -ax / user@workstation:/backup/dir/

Do this for all partitions of your hard disk.

(rsync runs over ssh)

In case you have to restore in worst case you'd have to
1) reformat and repartition your hard disk (keep a reference of your
   partition info!)
2) rsync the other way round

This is faster than dd, because only the actual data are transfered,
while dd transfers all the empty space as well. It also saves (a lot of)
disk space on your backup system.

In most cases it is *much* faster than dd, since it's rather unlikely
that you'll break your whole disk, ie. wipe all the data on disk. In
this case, the restore process will only have to replace those files
that are actually changed, ie. broken -- typically only a tiny fraction
of your disk.

YMMV, take care,
