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

How about this:
#!/bin/sh
target=$HOME/org/backup
mkdir -p "$target" && \
find "$HOME" -type f -name '*.org' ! -path "$target/*" \
-exec cp -t "$target" {} +

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 user command
26 * * * * root cd / && 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 ?
Thanks

Ah, I thought that you'd run it from your personal crontab. So yes,
write paths from root's point of view.

With "crontab -e" in Debian system.

You should probably read the manual page of "find" and learn all the
relevant options. But here's my new version which uses full paths.
#!/bin/sh
dir=/home/USERNAME
target=$dir/org/backup
mkdir -p "$target" && \
find "$dir" -type f -name '*.org' ! -path "$target/*" \
-exec cp -t "$target" {} +

[I replied to Sanjib privately on the grounds that it's OT for the list,
but let me add a couple of notes to this thread before we shut it off
as completely OT: cron issues are hardly germane to org.]
o Adding personal items to root-owned crontabs is a *bad idea* indeed.
o One should try the script by hand before trying to incorporate it into cron:
much easier to debug.
o cron operates in a restricted environment: just run `env' as a cron job to
find out what it knows (hint: not much).
o Quite apart from cron issues, the backup method in the script is
fundamentally flawed in my opinion: iiuc, it flattens the hierarchy,
so if you have org files with the same name in different directories,
only *one* will be saved into the backup directory - hardly a reliable
backup.

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.
Footnotes:
[1] The OP wanted to aggregate all org files in his home area to a
specific backup directory.

Please don't. 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.
Regards,
Achim.

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.
