Hack to backup apps packages

I think I found a simple way of saving a copy of any installation package (whether coming from Nokia Store or manual apt-get command), at installation time.
It is a one line hack, so I'm not going to wrap it into a user-installable package.

So, open a terminal session as root, go to /etc/apt/apt-conf.d/, launch your favorite editor and create a file named "02backup" containing the following:

Code:

Dpkg::Pre-Install-Pkgs {"BKPDIR=/home/user/MyDocs/AptBackup/; mkdir -p $BKPDIR; while read pkg; do cp $pkg $BKPDIR; done"};

That's all.
Since the next installation, a directory /home/user/MyDocs/AptBackup/ should be created and all packages should be copied there.
I haven't tested with packages that download dependencies, but I believe also said dependencies will be 'backupped'.
Note: you may want to disable this feature if you are going to upgrade to a newer PR release, otherwise your upgrade will be slow and your storage getting filled.

It seems that backdeb tries to repackage an app, kind of 'regenerating' the installation package.
What I'm proposing instead is to save the original package 'as is' at installation time (plus, no special action is needed to do that).

Re: Hack to backup apps packages

How about making a backup of INSTALLED apps?

You use the application mentioned in ibrakalifa's post.
Other choice could be to reinstall app (remove & reinstall if from Store, or 'apt-get --reinstall install' from command line)

You must have mistyped something, there are no problems in accessing /etc/ directory, even as non-root.

Re: Hack to backup apps packages

Okay got it, it's actually apt.conf.d and not apt-conf.d

Here is a Debian package that achieves the exact same thing (I just found this thread). Thanks minimos for this great idea!

P.S. You can append filenames with .deb after they are copied to the AptBackup folder. This will cause filebox, etc to show the proper icon.

Re: Hack to backup apps packages

Hi! After installation of this package all other packages (not from Store) is not installing (error "Installation aborted"). Please, check it and fix )

Re: Hack to backup apps packages

Try with this line:

Code:

Dpkg::Pre-Install-Pkgs {"BKPDIR=/home/user/MyDocs/AptBackup/; if [ ! -d $BKPDIR ]; then mkdir -p $BKPDIR; fi; while read pkg; do cp $pkg $BKPDIR; done"};

This is what I have and iirc modified that, because apt/dpkg bails out on any error (mkdir returns "1" when directory already present).

Re: Hack to backup apps packages

modified aptbackup script to be more flexible ;)
aptbackup.sh automatically changing file extension to .deb before copying
/etc/apt/apt.conf.d/02backup

Code:

Dpkg::Pre-Install-Pkgs {"while read pkg; do /home/user/aptbackup.sh $pkg; done"};

/home/user/aptbackup.sh

Code:

#!/bin/sh



PKG=$1

BKPDIR=/home/user/MyDocs/AptBackup

FNAME=$(echo $PKG | sed -re "s/.*(\/)([^\/]*$).*/\2/" | sed -e "s/\.[^\.]*$/.deb/")

mkdir -p $BKPDIR

cp -f $PKG $BKPDIR/$FNAME;

dont forget to chmod +x aptbackup.sh ;)

Nice idea! BTW I always wondered why the packages from Ovi (and especially their file extensions) can have such wacky names :D

Re: Hack to backup apps packages

Hmmm...
You mean if previous file looks like:

Code:

echo 'Dpkg::Pre-Install-Pkgs {"BKPDIR=/home/user/MyDocs/Downloads/OVIcatch; if [ ! -d $BKPDIR ]; then mkdir -p $BKPDIR; fi; while read pkg; do cp $pkg $BKPDIR; done"};' > /etc/apt/apt.conf.d/02backup

Now it include:

Code:

echo 'Dpkg::Pre-Install-Pkgs {"while read pkg; do /home/user/aptbackup.sh $pkg; done"};' > /etc/apt/apt.conf.d/02backup

and your new script ?
I'm right ?

PS. Checked, it work perfectly :)
