| Lubuntu linux Tips | ZipRoot zip your OS to a file for backup |
| You should first read about How to Clone your root partition to a backup
stick. This script will compress a mounted backup stick to a .tgz (tar.gz) file. There will be a time when you've run out of backup usb sticks. And you might want to archive the backups. This script merely compresses any attached backup disk to a .tgz file. The compression script is ziproot. The opposite (recovery) script is unziproot. It is NOT advisable to zip the live system ('/'). Make sure you just archive the backup stick. In this example it is sdb1. You will need another free partition to save the coompressed file. In this example it is sda4. e.g ziproot sdb1 sda4 will zip /mnt/sdb1 to /mnt/sda4/rootbackup.tgz
ziproot #!/bin/bash
#e.g ziproot sdb1 sda4 - zips /mnt/sdb1 to /mnt/sda4/rootbackup.tgz if [[ "$1" == "" || "$2" == "" ]]; then echo please specify ziproot source dest; exit; fi if [ `whoami` != root ]; then echo Please run as root or sudo; exit fi echo zipping root on /mnt/$1 to /mnt/$2/rootbackup.tgz echo enter to continue or ctrl-c to cancel read umount /dev/$2 2>/dev/null mkdir /mnt/$2 2>/dev/null mount /dev/$2 /mnt/$2 rm /mnt/$2/rootbackup.tgz >/dev/null umount /dev/$1 2>/dev/null mkdir /mnt/$1 2>/dev/null mount /dev/$1 /mnt/$1 sync tar -cvpzf /mnt/$2/rootbackup.tgz --one-file-system -C/mnt/$1/ ./ #-exclude=/mnt/ #--exclude-from=excludes.txt echo output: /mnt/$2/rootbackup.tgz echo done e.g unziproot sdb1 sda4 will unzip /mnt/sda4 to /mnt/sdb1/rootbackup.tgz
The parameter ordering is the same but the action is in the
opposite direction.Make sure you unzip back to the same usb stick partition otherwise the stick will not boot, (and you might have to use prime-boot to re-prime it again). unziproot #!/bin/bash
#e.g unziproot sdb1 sda4 - unzips /mnt/sda4/rootbackup.tgz to /mnt/sdb1 echo unzipping /mnt/sda4/rootbackup.tgz to /mnt/$1 if [ "$1" == "" ]; then echo please specify destination e.g sdb1; exit; fi if [ `whoami` != root ]; then echo Please run as root or sudo; exit fi umount /dev/$1 2>/dev/null mkdir /mnt/$1 2>/dev/null mount /dev/$1 /mnt/$1 sync tar -xvpzf /mnt/sda4/rootbackup.tgz -C /mnt/$1 echo output: /mnt/$1 echo done It is up to you rename and organise your backup files. It's not something you have to do everyday so it should not be a problem. |
