Full, Safe And Easy-to-restore Backup

[daniel3000]

Hello, especailly the ROM makers,

I'm still looking for "the best" backup solution for my SL-C3000.

With the best, I mean:

Full backup, size and speed doesn't matter. It should contain "everything", including ROM, data files on hard drive and configuration settings of all possible places (/etc in flash, Settings in home etc).

Easy restore, simply plug in a CF card and restore, just like flashing the Cacko ROM anew (may include two or three steps with a reboot in between.

After the process, the backed up state of the machine should be resotred exactly. That way, it should be possible to clone an entire setup or to restore the last working state after a hardware / bad software failure.

Is it possible to use the way ROM makers (Anton?) make their ROM images, and just perform some more steps for backing up / restoring the hard drive contents etc.?

Thanks

daniel

in D+M Menu you have an option to NAND backup the flash
and you have also an option to backup the whole drive, but this solution need at least 4GB + the flash size as storage.

Aha, thanks. That's a beginning.

A few more questions:

1. Can this kind of backup be done from outside that D+M menu?

2. Does this kind of backup (NAND) cover all data which is not on the hard drive or on other external media, i.e. does a NAND backup and an additional hard drive backup really cover ALL damagable data of the Zaurus?

3. was does NAND mean in this context? Is it the flash technology used (NAND flash)?

4. If I flash the Cacko ROM onto my C3000, it does not only flash the flash memory but also prepares / writes parts of the hard disk. Are these the two different steps of the Cacko flash process (i.e. 1st step NAND/flash, 2nd step hard drive) or how does it work?
I'd like to know more details about the process so I can develop ideas for backup solutions.

5. To circumvent the need for a 4G+ external storage for the hard drive image, one could do a NAND backup and then a "manual" zipped backup of the hard drive to have a full backup, or not? (something like
dd if=/dev/hdc bs=1M | gzip -c | dd of=/mnt/card/hdbackup.gz )

6. How can such a self-made D+M-menu NAND backup be restored? The same way as I start the Cacko flash process?

Thanks a lot

I was under the impression you couldn't NAND backup a C3000 as the backup takes an image of the whole 4gb hard disk. Unless you've a similar sized flash card, I'd not suggest it was possible.

I'm no expert though.
