[O] org back up
Hi, I wanted to set a cron job for backing up all my org files as suggested by Suvayu Ali. #!/bin/bash mkdir -p ~/org/backup \ find $HOME -type f -name '*\.org' ! -path $HOME/org/backup/* \ -exec cp -t ~/org/backup/ \{\} \; In Ubuntu I have put the bash file in cron.daily but it seems it is not working. A little googling says I need to give full path for directories. may I modify it like this ? I am not sure about the find $HOME part and guess rest of the paths are correct. #!/bin/bash mkdir -p /home/USERNAME/org/backup \ find $HOME -type f -name '*\.org' ! -path /home/USERNAME/org/backup/* \ -exec cp -t /home/USERNAME/org/backup/ \{\} \; Can anybody confirm the correctness of this code? Thanks - *Sanjib Sikder *Ph.D. Fellow Chemical Engineering IIT Bombay* *

Re: [O] org back up
Hi, No it is not working. I copied the code in the backup.sh file and put into /etc/cron.hourly --- #!/bin/sh target=$HOME/org/backupOrg mkdir -p $target \ find $HOME -type f -name '*.org' ! -path $target/* \ -exec cp -t $target {} + echo Daily Org Files Backup Successful: $(date) /home/USERNAME/mybackupOrg.log --- And then changed the crontab hourly setting to 26. /etc/crontab # m h dom mon dow usercommand 26 ** * *rootcd / run-parts --report /etc/cron.hourly --- Even after 26th minute, there is no sign of the code in work. Is it that $HOME is not allowed and I need to give full path ?

If you consider this a viable backup strategy, you might just as well have no backup at all. You should use a VCS like Git to be able to revert to an earlier version of your files. If necessary, make Org a sub-project (that's specific to Git of course) so that not only your files but also Org will move back in time when you request that. Defending against loss of data is only really possible if you copy them to a different medium in a different location. Again, Git would help you do that by allowing you to use a remote repository on some server you can access.

Hi, I do not find personal crontab file. how do I create it ? crontab -e says my personal file is not there If I want to run it as root then how do modify the following code as it is nor working .. --- #!/bin/bash mkdir -p /home/USERNAME/org/backup \ find $HOME -type f -name '*\.org' ! -path /home/USERNAME/org/backup/* \ -exec cp -t /home/USERNAME/org/backup/ \{\} \; echo Daily Org Files Backup Successful: $(date) /home/USERNAME/mybackupOrg.log - Thanks - *Sanjib Sikder *Ph.D. Fellow Chemical Engineering IIT Bombay* * On Thu, Oct 18, 2012 at 12:38 AM, Teemu Likonen tliko...@iki.fi wrote: Sanjib Sikder [2012-10-18 00:32:00 +0530] wrote: Even after 26th minute, there is no sign of the code in work.

Re: [O] org back up
I second using a VCS instead. I have my Org files in a Bazaar repo, and a cron job setup to commit hourly if changes occur.

Hello Sanjib and others, Sorry to continue with this terribly off-topic thread, but as the person who wrote that snippet I felt I should clarify.

If you look at the original thread, my solution was a suggestion for the specific case[1] of the original poster of that thread. This is _not_ a reliable way to back up your files. As others have mentioned, a distributed version control system like git, mercurial or bazar would be well suited. However I personally believe in redundancy being the best backup and use at least 3 ways to backup my org files: git, dropbox and rsync to a different physical drive.
