[SLUG] rdiff-backup
Wearing my I wish somebody had said this, useful, sharing cap and not my dragons and swords one I declare that, except for those interested in pages- n-pages of python stack traces or very simple systems, rdiff-backup is unmentionably awefull. I backup daily 4 systems with a couple of 100s G each. rdiff-backup does not play with other versions, the client and server machines are different, and rdiff-backup needs to be on both machines. Some work, some dont. All versions complained about obsolete modules. As you may expect, winter power fails during the backup happened. This resulted in chaos that took significant manual input to fix. http://www.sanitarium.net/golug/rsync_backups.html shows rsync is easy and justworks(tm) Here is a snip of my rsync backup script: It uses 1 backup+30 tinybits of space for the backup A tiny bit of logic to avoid regetting everything after a failure would help ie don't cycle and copy unless all suceeded #! /bin/bash DAY=`date +%a` Cycle all the daily backups rm -fr /backup/tigger.etc.30 rm -fr /backup/tigger.home.30 rm -fr /backup/tigger.mail.30 rm -fr /backup/tigger.root.30 ... for (( i=29 ; i ; i-- )) do let j=$i+1 if [ -d /backup/tigger.etc.$i ] [-d /backup/tigger.etc.1 ]; then mv /backup/tigger.etc.$i /backup/tigger.etc.$j fi if [ -d /backup/tigger.home.$i ] [-d /backup/tigger.home.1 ]; then mv /backup/tigger.home.$i /backup/tigger.home.$j fi if [ -d /backup/tigger.mail.$i ] [-d /backup/tigger.mail.1 ]; then mv /backup/tigger.mail.$i /backup/tigger.mail.$j fi if [ -d /backup/tigger.root.$i ] [-d /backup/tigger.root.1 ]; then mv /backup/tigger.root.$i /backup/tigger.root.$j fi ... done tigger echo tigger /tmp/mail date /tmp/mail rsync -xa -e ssh --exclude=.gvfs --delete --link-dest=/backup/tigger.home.2 tigger:/home/ /backup/tigger.home.1 rsync -xa -e ssh --exclude=.gvfs --delete --link-dest=/backup/tigger.root.2 tigger:/root/ /backup/tigger.root.1 rsync -xa -e ssh --delete --link-dest=/backup/tigger.etc.2 tigger:/etc//backup/tigger.etc.1 rsync -xa -e ssh --delete --link-dest=/backup/tigger.mail.2 tigger:/var/spool/mail/ /backup/tigger.mail.1 ssh tigger df -h | grep '^/dev' /tmp/mail ...

We are just starting to deploy Bacula after some examination. The matter with backups is not just to make them - but also to manage a catalog to help you find the right file when you have to restore things. #! /bin/bash DAY=`date +%a` Cycle all the daily backups rm -fr /backup/tigger.etc.30 rm -fr /backup/tigger.home.30 rm -fr /backup/tigger.mail.30 rm -fr /backup/tigger.root.30 ... for (( i=29 ; i ; i-- )) do let j=$i+1 if [ -d /backup/tigger.etc.$i ] [-d /backup/tigger.etc.1 ]; then mv /backup/tigger.etc.$i /backup/tigger.etc.$j fi if [ -d /backup/tigger.home.$i ] [-d /backup/tigger.home.1 ]; then mv /backup/tigger.home.$i /backup/tigger.home.$j fi if [ -d /backup/tigger.mail.$i ] [-d /backup/tigger.mail.1 ]; then mv /backup/tigger.mail.$i /backup/tigger.mail.$j fi if [ -d /backup/tigger.root.$i ] [-d /backup/tigger.root.1 ]; then mv /backup/tigger.root.$i /backup/tigger.root.$j fi ... done Consider looking at savelog or logrotate. I'm not sure where savelog popped up from but it appears to be a script-friendly interface to one-off logrotates.

On that note, you can use the rdiffWeb[0] tool to browse your rdiff-backup revisions and recover files.

[SLUG] USB ports
I bought a huge backup drive and went to plug it in today and it kept mounting and unmounting it spawning windows along the way. Strange thing is I plugged the same drive into the rear of the computer and it now works correctly. Is it possible that they are two different types of USB port?

Sounds like the first port you plugged it into might not have enough power to run the usb hdd? I know some Apple notebooks (just off the top of my head) have slightly different power ratings for different usb ports on the same machine. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Look at the kernel* package logs - you may find its fixed already and be able to copy the fixed one in by hand. Spot on Rob - thanks very much. Found a post (https://bugs.launchpad.net/ubuntu/+source/linux-backports-modules-2.6.24/+bug/229535) where someone had simply deleted the .list and .postrm files so tried this, followed by aptitude purge and shazam, problem solved, happy new user.
