dump ramdisk to cf?

[shadowkwarrior]

theres probably a easy way to do this, but my linux skills are somewhere around non-existant, so bear w/ me please. ive got my zaurus setup just like i want right now, going on a trip next week and was wondering if it was possible to dump everything in the ramdisk to cf, so if i mess it up i can flash from image on cf and restore what was on ramdisk this way i wont have to reinstall all my programs again, thanks

Without knowing what version Z you have I can only suggest NAND backup, but the backup/restore app on the C760 does pretty much what you want. NAND backup will backup everything in one big package (132 Mb for C760)

oops, im using a sl-5500 running tkc.rom2.0 alpha3, what is nand backup?. the thing is i wont have a computer with me, so i have to restore from cf and dont want to set up all the apps again. thanks

thats was me, forgot to login

nand backup is for the cxxx machines only.

I suppose you could do:

cd /mnt/cf
tar -cf ram_backup.tar /mnt/ram
gzip ram_backup.tar

But I don\'t know whether this even exists for you, nor do I know how easy it would be to write the data back.

You should be able to get away with backing up your /home/zaurus and /home/root directories and (depending on how the symlinks work) /etc and /opt

Isn\'t there a backup app on that ROM like there is on the Sharp ROMs?

thanks, if i wanted to create a script for it would s work? and where do i put the script?

#!/bin/bash
su
cd /mnt/cf
tar -cf backup.tar /home/root
gzip backup.tar
exit 0

thanks again...maybe after messing w/ the zaurus for a while i\'ll actually learn linux :-p

Yeah that should work, but as you\'re using \'su\' I assume you run as \'zaurus\' normally. In that case there may be files in the /home/zaurus/ directory which you could do with saving. You\'ll also have to check that /etc and /QtPalmtop are actually subdirectories of /home/root otherwise you won\'t save much (you\'ll save the data files, but not the applications).

Probably best that someone who actually runs tkc advises you.

If you\'ve not got time for that, I\'d just take the ipks on your CF card and backup /home/<user>/applications and its subdirectories and possibly also some of the (possibly hidden) subdirectories directly under /home/<user> which contain other config data. Probably also worth backing up parts of /etc (for example /etc/ppp if you have dialup scripts).

instead of
tar -cf backup.tar /home/root

i\'ll just use this
tar -cf backup.tar /home
tar -cf backup.tar /opt
but, the script doesnt seem to run, i have .sh associated w/ the terminal app, so it should work... can u enlighten me?

[shadowkwarrior]

that was me again, hmm i suppose what i need is a script tutorial for zaurus, the one in the how to section didnt help as much as i would like.


hmm i tried to execute by typing /mnt/cf/backup.sh in terminal, but it just says \"backup: not found \"

#!/bin/bash
su
mkdir -p /mnt/cf/backup
cd /mnt/cf/backup
tar -cf home.tar /home/
gzip home.tar
tar -cf opt.tar /opt
gzip opt.tar
echo \"backup successful\"
exit 0

anything i did wrong?

[Joshp]

Try this:

#!/bin/bash
su  -c  `
mkdir -p /mnt/cf/backup
cd /mnt/cf/backup
tar -cf home.tar /home/
gzip home.tar
tar -cf opt.tar /opt
gzip opt.tar
echo \"backup successful\"
exit 0
`

Let me know if this works.

hmm, still not working for me :-( what do i have to do to run the script? in terminal i can just put backup.sh if thats the filename right? does the script have to be located anywhere specifically? i had it in /mnt/cf and /home/QtPalmtop/bin and tried to run from both, neither did anything

heres a screenshot if that helps ...

Ok.  I can only think of one more thing to try and thats to change #!/bin/bash to #!/bin/sh.  What rom are you running?

Hope that works.

[shadowkwarrior]

hmm, nop. im running tkc.rom2.0alpha3 , is there a package i need to run shell scripts?

[Joshp]

I don\'t think so.  But I may be worng.  I run the script on both my tck.rom1.0 and my OZ 3.3.5 and it ran on both.  I have no idea what the problem is.

hmm so weird... especially when it works if i just copy and paste script in manually...
