You are lucky - It -did- work. If it didn't, your system wouldn't have booted.
Either way though, the V0.3x series is old and only for people who need to restore old backups. The new version is safer, and while it has it's own glitches, it works better overall.

Huh, I'll try removing the -y option next time I edit things.

Not currently. This is a planned feature, but not in the current version. It -is- possible to convert a BackupMenu image to a Nokia Flasher rootfs image, but it requires a Linux PC with mtd-utils.
Once you have that, the process is as follows(Note, based on this, from Stskeeps:
Code:
#make a temp dir:
mkdir rootfs
#Extract your rootfs tarball:
tar xf *date*-rootfs.tar -C ./rootfs/
#Now, make a file called "ubinize.cfg", edit it, and paste the contents of *note 1*
#Make a ubifs image with our rootfs contents:
mkfs.ubifs -m 2048 -e 129024 -c 2047 -R 4MiB -r ./rootfs/ -v ./base.ubi.img
#Package it up:
ubinize -o ./rootfs.img ubinize.cfg -m 2048 -p 128KiB -s 512
#...And write it to your N900:
flasher-3.5 -r ./rootfs.img -f -R
Note 1:
Code:
[ubifs]
mode="ubi"
image="./base.ubi.img"
vol_id="0"
vol_size="200MiB"
vol_type="dynamic"
vol_name="rootfs"
vol_alignment="1"
vol_flags="autoresize"
NOTE: different versions of mtd-utils sometimes make corrupt images. I find "mtd-utils_20090606-1_amd64.deb" worked for me.
I have tested alternative compression types on my rootfs.tar.

Using no parameter in the mkfs.ubifs command, as above, gives a finale img file 192,806,912 bytes large.

Using zlib compression like that:
Code:
mkfs.ubifs -x zlib -m 2048 -e 129024 -c 2047 -R 4MiB -r ./rootfs/ -v ./base.ubi.img
or a mixed compression like that:
Code:
mkfs.ubifs -x favor_lzo -X 5 -m 2048 -e 129024 -c 2047 -R 4MiB -r ./rootfs/ -v ./base.ubi.img
gives a much smaller img file to flash: 168,951,808 bytes.

The difference is quite large: 23,855,104 bytes.

Maybe this is the key to the problem of disappearing space when restoring.

I am not in the mood of trying a restore - I need my N900 working... but someone more inclined to experiments could try and see if flashing images with different compression types results in different free space in the rootfs.

You don't need to reflash it you can use nandsim to the same effect - even on-device if you apply a diff and compile your own kernel (it needs cache_file as otherwise all the RAM gets used up, I've asked Titan to add it to kernel-power, but no response as of yet).

I keep getting an error message when I try to back up:

Mounting the OptFS...
Backing up Optfs with Tar---
Error: retured 2.
Press any key to continue
OPtFS Backup complete
all operations completed successfully

Get the same message on the root backup.

Although it says operations completed successfully but I do not think the backup was successful because it takes no time at all and of course because of the error message as well.

Any ideas on how I fix the problem?

Check your *drive*/systemBackups folder - what files exist and what size?

MyDocs gets backed up too? That's new to me. How do you do that?

...it's also not in the backup included. Perhaps this is the reason.

It's more easier to connect your N900 via usb to your PC and backup MyDocs manually. BackupMenu with a Backup including MyDocs will be possible. But your MyDocs is 27GB large. And in this case you will only be able to backup to your SD card... and not everybody owns a empty 32GB micro SD card.

So I guess the current solution is the best one for everybody.
