Hey Robbie,
I'm sure you've already written your own script for it, but if not, here's a simple one that anyone can use to perform an online backup, compatible with BackupMenu.
It does some basic sanity checks and warns the user that they need to quiesce I/O on the phone during the backup.
I've restored from these images a couple times and all is well.
PS - I modified your main script to modprobe ext4 before mounting the SD card and I was able to successfully restore from it.

hi
Really a great App.
As I've seen, it saves and restores the home directory too. I think there should be an option for that/should not do it.
(Sorry if it was mentioned earlier in the thread)

I thought you meant specify opt and rootfs separately.
Opt lives in /home; I could specify /home/opt explicitly, but I'm not sure if it would have other consequences. Are you looking to be able to exclude your personal preferences in a restore, or restore only your prefs?
Here's my original reply:
Updated script attached.
Code:
5 root@glamb-n900 [~]# ./backup.sh ./backup.sh: error: no target specified. Usage: ./backup.sh <sd|internal> [-rootonly|-homeonly]
Code:
# Include both home and rootfs? doHome=1 doRoot=1
If people start to use it and Robbie doesn't have his own online backup script I could rewrite this one to implement features like scheduling, or possibly a UI.

As the procedure goes fast, I thought it would be a good idea to have two different sets of software. Sharing the same /home/user directory seems to be no problem. So i have to exclude my personal preferences in a restore. Therefore I must be able to backup/restore my personal preferences separately.
home and opt should be separated. home is user data and has nothing to do with the system itself. opt belongs to root.
Separating this in BackupMenu would improve this software with greater possibilities.
I think. Could be wrong of course.

@Robbiethe1st: sorry to bump this issue, but I hope you are going to add the feature I asked before, namely the possibility to mkfs.ext3 for the optfs. This is the single thing that would make backupmenu independent from an external device.
In fact, now if my optfs gets seriously damaged, and a fsck isn't solving the issue, the only thing I can do is reformatting it from an external pc connected through usb, using option w of backupmenu. If I could instead reformat it through backupmenu (as opposed to erasing all files - is it option e or q? that is useless in this case because it leaves the filesystem in an unstable state) everything could be done autonomously, and then restoring optfs would be a breeze.
Thanks for your attention.

Ok, so there are a couple potential problems. If you restore rootfs without restoring /opt, you'll have a lot of invalid package metadata. The system will be in an ugly, inconsistent state.
If you exclude /home/user, that's probably ok.
So possibilities include:
Only /home/user (ie. just preferences)
Only rootfs, /opt
rootfs, /opt and /home/user
Does that make sense?
I'm not sure if these backups would be compatible with the way BackupMenu works (ie., I think it rm -r's /home before restoring the optfs backup), so it would take some changes to BackupMenu itself before my script could produce anything useful.

All times are GMT. The time now is 12:40.
Not sure. My program -cannot- damage the actual bootloader etc - A reflash is what you need.
Try flashing the way I've talked about several times in this topic - without using the "u" key.
If that doesn't work, you can Cold Flash it, there's -no way- to brick the n900 via software, provided all the hardware's OK.
@m4:
Yea, I know.
My projects: BackupMenu - OS Backup & restore | Video: Flashing your n900(LiveCD)
My devices: N770 + 8GB SD card soldered internally, N900 with 8GB SD card + Custom OC(125-950 typically).
OC freqs: 0:22,90 125:22,90 250:28,180 500:30,360 550:32,400 600:34,430 700:39,430 750:41,430 805:45,430 850:47,500 900:50,500 950:54,500 1000:58,500 1100:67,520 1150:71,520
