SD card backup / copy: how to ?

[davenull]

is that true that for the RPi there is no single backup-program or script or what ever which works out of the box?
e.g., choose target backup drive by commandline parameter or by menu (listing all available drives / just all USB drives)?

like e.g., most simple:

Code: Select all

sudo ./backup  /media/pi/usb120drv   # usb120drv == drive name 

In case something like that doesn't exist yet, then that would be really rediculous...

Not one that fits the extremely narrow range of constraints that has been put on the problem...

[davenull]

that cannot - that MUST not be true!
How long does Linux and Unix already exist?
And NO BACKUP PROGRAM to a plugged-in USB drive available ?!?

Of course there are, from free to $$$$. rsync has already been mentioned as has dd'ing the partions.

If you really want a one liner:

Code: Select all

sudo tar --exclude=/media/* --exclude=/proc --exclude=/dev --exclude=/tmp --exclude=/run cvzf /media/pi/usb120drv/pibackup.tar.gz /

The position of the excludes depends on the version of tar. I've not tested the above as I use rsync...

[davenull]

thank you!
neverless there is this error:

pi@raspberrypi:~ $ sudo tar --exclude=/media/* --exclude=/proc --exclude=/dev --exclude=/tmp --exclude=/run cvzf /media/pi/usb120drv/pibackup.tar.gz /
tar: Eine der Optionen „-Acdtrux“, „--delete“ oder „--test-label“ ist notwendig.
„tar --help“ oder „tar --usage“ gibt weitere Informationen.

...?

ps,
I'm a complete beginner and my English is very poor, especially I don't understand sort of slang like dd'ing :-/
rsync appears extremely complicated, except there is 1 single install programm for the whole installation (like setup.exe for windows programs)
and just 1 command to start (like double-click on sort of "rsync.exe"
and adjust the settings (like target drive) interactively.

[davenull]

ps,
all directories of /pi/ also should be backup-ed
and why exclude proc and dev?

Well, I did say that may have the alter the position of the excludes, try:

Code: Select all

tar  cvzf /media/pi/usb120drv/pibackup.tar.gz / --exclude=/media/* --exclude=/proc --exclude=/dev --exclude=/tmp --exclude=/run

Seems to do something...I'll let you know when it finishes

that looks better...

did not find the USB target drive
nevertheless, the USB drive is plugged in and can be accessed via the file explorer

[asandford]

and why exclude proc and dev?

They are psuedo-filesystems populated by the OS at runtime, they probably are empty on the SDcard (if they exist at all).
You exclude /media as you don't want it archiving the archive file...

no,...

Try putting sudo in front of the tar command (as in my first example), or:

Code: Select all

cd /media/pi/usb120drv/
sudo tar cvzf ./pibackup.tar.gz / --exclude=/media/* --exclude=/proc --exclude=/dev --exclude=/tmp --exclude=/run

[davenull]

Mine's just failed with

Code: Select all

tar: Exiting with failure status due to previous errors

But there are no errors...
However, it did create a file:

Code: Select all

-rw-r--r-- 1 root root 1473845343 Jan  2 22:52 pibackup.tar.gz

I'm running wheezy from a hdd with 135GB free, so it's not a space issue.

Best try rsync

Code: Select all

sudo apt-get install rsync -y
mkdir -p /media/pi/usb120drv/pibackup
cd /media/pi/usb120drv/pibackup/
sudo rsync -avz --delete --exclude /sys --exclude /tmp --exclude /proc --exclude /run  --exclude /media/* / .

The excludes can be written to a file if required.

[davenull]

it does not find the target USB drv

pi@raspberrypi: $ cd /media
pi@raspberrypi:/media $ cd usb120drv
bash: cd: usb120drv: no such file or directory
pi@raspberrypi:/media $

[asandford]

it does not find the target USB drv

pi@raspberrypi: $ cd /media
pi@raspberrypi:/media $ cd usb120drv
bash: cd: usb120drv: no such file or directory
pi@raspberrypi:/media $

I was using you previous example:

Code: Select all

sudo ./backup  /media/pi/usb120drv   # usb120drv == d

If your drive is mounted to somewhere else, then use that (use df -h to find the mountpoint).

what is "mounted" ?
I plug it in and it is opened in the file manager..
I can see the file tree
\media\pi\usb120drv

[asandford]

Unix systems are case sensitive (unlike windows), so /media/pi/USB120DRV is not the same as /media/pi/usb120drv
So, try

Code: Select all

mkdir -p /media/pi/USB120DRV/pibackup
cd /media/pi/USB120DRV/pibackup/
sudo rsync -avz --delete --exclude /sys --exclude /tmp --exclude /proc --exclude /run  --exclude /media/* / .

[davenull]

OMG ...

cd USB120DRV is fine

[davenull]

pi@raspberrypi:/media/pi/USB120DRV $ sudo tar --exclude=/media/* --exclude=/proc --exclude=/dev --exclude=/tmp --exclude=/run cvzf /media/pi/USB120DRV/pibackup.tar.gz /

yes.
definitely: yes.
