Editing EPrints Live CD Help (section)

= Storing your Archive on a Memory Stick (With Bash Scripts) =

By using the live cd, any changes made will be lost when the system is shut down to avoid this we have created some scripts which backup your archive onto a memory stick.

These scripts should be stored somewhere on the memory stick and the files are stored in a folder called "live_cd" relative to the position to the scripts.

Extract [http://www.eprints.org/files/eprints3/mem_key/mem_key.zip this file] onto your memory stick and execute as root:

== Archive only Backup ==
This will only backup your archive, it will not include any of the global plugins or settings which apply to all repositories.
  root@ubuntu$ bash archive_to_usb.sh archive_name

== Complete EPrints Tree Backup ==
This will backup everything in your eprints3 tree.
   root@ubuntu$ bash all_to_usb.sh archive_name
  
Don't forget to safely unmount the memory stick, on the live cd close any windows which popped up when the memory stick was inserted and then as root:
  root@ubuntu$ cd /
  root@ubuntu$ umount /media/disk

=== Script Details ===

The script backs up both your archive and the related database by doing the following, it assumes you have not set a root password  on the mysql database:

archive_to_usb.sh:

  #!/bin/bash
  if [ "$1" = "" ]
  then
    echo "No Archive Specified"
  else
    FOO=`pwd`
    mkdir "$FOO/live_cd"
    rm -fR "$FOO/live_cd/$1"
    mkdir "$FOO/live_cd/$1"
    tar -cf "$FOO/live_cd/$1/$1.tar" /usr/share/eprints3/archives/$1
    mysqldump -u root $1 > $FOO/live_cd/$1/$1.sql
    echo "DONE"
  fi

all_to_usb.sh:

  #!/bin/bash
  if [ "$1" = "" ]
  then
        echo "No Archive Specified"
  else
   FOO=`pwd`
   mkdir "$FOO/live_cd"
   rm -fR "$FOO/live_cd/eprints3"
   mkdir "$FOO/live_cd/eprints3"
   rm -fR "$FOO/live_cd/$1"
   mkdir "$FOO/live_cd/$1"
   tar -cf "$FOO/live_cd/eprints3/eprints3.tar" /usr/share/eprints3/*
   mysqldump -u root $1 > "$FOO/live_cd/$1/$1.sql"
   echo "DONE"
  fi    

== Restoring your archive from memory stick ==

Don't forget to follow the step above to configure ePrints to run from the live cd first!

Locate the place where you extracted the files to previously on your memory stick and as root:

== Archive Only ==
  root@ubuntu$ bash usb_to_archive.sh archive_name

== Complete EPrints Tree ==
  root@ubuntu$ bash usb_to_all.sh archive_name  

=== Script Details ===

Pretty much the opposite of the other script:

usb_to_archive.sh:

  #!/bin/bash
  if [ "$1" = "" ]
  then
    echo "No Archive Specified"
  else
    FOO=`pwd`
    rm -fR /usr/share/eprints3/archives/$1
    tar -xf live_cd/$1/$1.tar -C /
    echo "drop database $1" | mysql -u root
    echo "create database $1" | mysql -u root
    mysql -u root $1 < live_cd/$1/$1.sql
    echo "DONE"
  fi 

usb_to_all.sh:

  #!/bin/bash
  if [ "$1" = "" ]
  then
   echo "No Archive Specified"
  else
   FOO=`pwd`
   rm -fR /usr/share/eprints3/
   tar -xf live_cd/eprints3/eprints3.tar -C /
   echo "drop database $1" | mysql -u root
   echo "create database $1" | mysql -u root
   mysql -u root $1 < live_cd/$1/$1.sql
   echo "DONE"
  fi
