rsync - Jul 2010 - Rsync sequence

Hi all,

I am running Ubuntu server 10.04 and use rsync to do all my backups. I would
like to backup multiple directories to my external hard drive, but I am
faced with a problem on how to set up crontab -e to allow each rsync
statement to perform one after the other. Right now I have each one set to
run on different nights, but I would like them all to run the same night to
allow for a more efficient backup. I know I could just run them at different
times in the same night, but I don't want to chance one not completing
before the other starts. Can I just list them one after the other like so in
crontab -e:

# m h  dom mon dow   command
00 4 * * 7 rsync -auv --delete /Godfather/Music /Backup
                 rsync -auv --delete /Godfather/Documents /Backup
                 rsync -auv --delete /Godfather/Setups /Backup
                 rsync -auv --delete /Godfather/Pictures /Backup
                 rsync -auv --delete /Godfather/Backups /Backup
                 rsync -auv --delete /Godfather/Videos /Backup

This is my current crontab -e
# m h  dom mon dow   command
00 4 * * 7 rsync -auv --delete /Godfather/Music /Backup
00 4 * * 6 rsync -auv --delete /Godfather/Documents /Backup
00 4 * * 5 rsync -auv --delete /Godfather/Setups /Backup
00 4 * * 4 rsync -auv --delete /Godfather/Pictures /Backup
00 4 * * 3 rsync -auv --delete /Godfather/Backups /Backup
00 4 * * 2 rsync -auv --delete /Godfather/Videos /Backup

Thanks in advance!

This is hardly an rsync question...

I would put the commands in a separate shell script file:

#!/bin/sh

rsync -auv --delete /Godfather/Music /Backup
rsync -auv --delete /Godfather/Documents /Backup
rsync -auv --delete /Godfather/Setups /Backup
rsync -auv --delete /Godfather/Pictures /Backup
rsync -auv --delete /Godfather/Backups /Backup
rsync -auv --delete /Godfather/Videos /Backup


Then make the file executable (chmod +x) and then put the name of the
script in the crontab.

You may wish to also consider using a single rsync command :

rsync -auv --delete \
/Godfather/Documents \
/Godfather/Setups \
/Godfather/Pictures \
/Godfather/Backups \
/Godfather/Videos \
/Backup # backup destination

With this approach I am not sure which order the source directories will be
copied? If the execution order is critical then you are probably best to stick
to a separate command for each source directory in a script as has been
previously suggested.

Finally, I recommend excessing extreme caution when using the --delete option.
  
I hope this helps.
