The Zaurus backup tool basically shuts down Qtopia so all open files are closed and then tars up
/hdd2 and /home which become the backup image. This is much safer than the above approach
while Qtopia is still running. You should, however, gzip the backup image to save some space.
There is no real need to backup /hdd1 each time since it is a read-only partition and does not
change unless you have changed something on it manually or applied an update via flashing.
I have written a script called
hdbackup
which will backup /hdd3 by archiving and compressing each
directory separately and datestamping them so regular backups can be made by simply running a
single command.
Alternatively, you can connect your Zaurus to your Windows PC through the USB link cable and use
Windows backup software or anything else you like to backup the USB drive that the Zaurus is
recognised as. Since the USB PC connection is buggy, you might be better of enabling Samba and
then backup /hdd3 over the network or USB cable.
Lastly,don't forget about backing up your SD and CF card also. They can get corrupted or fail
without warning as well, so make sure you back them up to.
In addition, there is also a NAND backup feature in the Zaurus Diagnostic Menu which allows you to
backup the entire NAND. Since the C3000 only has 16MB of NAND flash and everything actually sits
on the hdd3, doing a NAND backup won't buy you much. On the C3100, however, everything is on
the NAND except for the data on /hdd3, thus making a NAND backup for the C3100 gives you a
reliable system image which you can use to restore your C3100 if you really mess it up. The same
is not the case with the C3000 so be very careful with what you flash your C3000 with.
To do a Nand Backup, you need a CF or SD card which can hold the entire Nand. A 256MB card
should be sufficient. To do a Nand Backup or Restore, do the following:
Turn off or suspend the Z
Unplug the Z and take out the battery
Press and hold the D and M keys simultaneously
Plug in the power
The Maintenance Menu should appear in a few seconds
Go to the third page in the menu
Select either Nand Backup or Restore
When finished turn off the Z
Put battery back in and start Z
Zaurus Restoration/Recovery
If you manage to corrupt your Zaurus configuration so badly that you cannot boot it anymore or
things just don't work any more, then you have several options to fix it.
Factory Reset
If you really messed up and just start over again without retaining anything, then just do a
factory reset and the Zaurus will revert to its initial Japanese ROM state.
Restore From Backup
If you have a backup, you can restore your previous settings contained in your backup files. If
you had to factory reset, then a restore can quickly get you to where you were before.
Command Line Recovery
This is by far the most advanced option. Use this to recover files that might not have been
backed up yet before doing a restore and/or factory reset.
Please refer to Trisoft's C3000 manual on how to do the above. It would be a waste of my time to
provide step by step instructions since they have it pretty much covered, and they even have
emergency backup images for you to use in case you dont't have a system backup.
If you have booted into the console for recovery, then you are using the /dev/mtdblock1 partition.
