Backup files from Linux laptop to Linux server

All automated (ie I don't think about it)

Use simple standard Linux command-line tools

Motivation

My situation Laptop that goes everywhere – my primary workstation Server, sits in my apartment. Doesn't do much other then hold files + serve as test bed for the occassional wacky experiment Wireless network

Server, sits in my apartment. Doesn't do much other then hold files + serve as test bed for the occassional wacky experiment

What I did Cron job on laptop which runs rsync script to mirror changes nightly at 10:10pm Monthly which takes a snapshot of subset of files and pushes these to Amazon S3 [Still in the future] Nightly rsync from server to Amazon S3

Rsync Is awesome! ” is an open source utility that provides fast incremental file transfer” - samba.anu.edu.au/rsync/ Used for mirroring + backup purpose

Tar + gzip Tar turns many files into one file – no built-in compression Commonly used with gzip or bzip2 (making, respectively *.tar.gz and *.tar.bz2 files

Small pieces loosly joined Tools reusable Designed to interoperate Can be used together in scripts in 1000s of different ways

Tools reusable

Designed to interoperate

Can be used together in scripts in 1000s of different ways

Easier to learn Use these different tools all the time Rsync to mirror changes from laptop to production (or devel) server Tar to uncompress files from internet Makes it easier to start a new scripting project
