Here is my advice:
install archivers/rar
and archivers/par2cmdline
The following script will split your file into 25meg chunks,
build a cd_9660 iso of them and provide a way to recover damaged files
just in case, later on.
assuming you file name is:
home.tar.bz2
then run the following script as:
./backup.sh home.tar {don't add the .bz2}
#!/bin/sh
if test $1
then
echo "mkdir $1; cd $1; rar a -s -m5 -v25m $1.rar
../$1.bz2"
mkdir $1; cd $1; rar a -s -m5 -v25m $1.rar ../$1.bz2"
echo "cd $1;par2 c -r15 -u $1 $1.part*.rar"
cd $1;par2 c -r15 -u $1 $1.part*.rar
echo "verifing archive"
par2verify $1/$1.par2
echo "mkisofs -JR -o $1.iso"
mkisofs -JR -o $1.iso $1
else
echo "command line syntax is \"backup.sh {bz2 file name to back
up}\""
fi
Note: this script is not tested so it may need a little tweaking, it
would also be improved if it could abort if the "par2verify $1/$1.par2"
step fails but I don't know enough about scripting to do that, does
anyone else?
