Linux Backup System using rsync, tar, gzip
Download as PPT, PDF7 likes3,003 views
The document describes an automated backup system for a Linux laptop to a Linux server using standard command-line tools like rsync and cron. It outlines the configuration of nightly backups and the philosophy of simplicity in tool usage. The overall goal is to maintain an efficient and understandable backup process for a mobile workstation and test server.

Linux Backup System using rsync, tar, gzip
- 1. Linux backup system Backup files from Linux laptop to Linux server All automated (ie I don't think about it) Use simple standard Linux command-line tools
- 2. Motivation
- 3. 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
- 4. 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

- 6. Rsync Is awesome! ” is an open source utility that provides fast incremental file transfer” - samba.anu.edu.au/rsync/ Used for mirroring + backup purpose
- 7. Cron ” Program that enables unix users to execute commands or scripts automatically at a specified time/date.” - Wikipedia Used extensively by all *nix systems and aspiring amateur Linux sysadmins
- 8. 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
- 9. Unix Philosophy Do one thing and do it well Rsync, tar, gzip, cron all do one task well
- 10. Small pieces loosly joined Tools reusable Designed to interoperate Can be used together in scripts in 1000s of different ways
- 11. 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
- 12. K.I.S.S Keep It Simple Stupid Simple tools make for simple systems that are easy to build, understand, and maintain
- 13. Odes to Simplicity ” Everything should be made as simple as possible, but no simpler.” – Albert Einstein "Simplicity is the ultimate sophistication" – Leonardo Da Vinci "It seems that perfection is reached not when there is nothing left to add, but when there is nothing left to take away" – Antoine de Saint Exupéry
- 14. Backups = peace of mind
