i need to make a scheduled backup of repository of subversion in ubuntu.
eg,backup the repository at 13.00 pm every Monday
may i need to write some hook scripts to do that?
and i also have to recover the backup of repository
if possible,i want to backup the trunk of repository
my repository is project1
/project1
/trunk
/tags
/branches
any one can give some suggestion?

You can use crontab to schedule tasks in Linux.

Type the following command:

Code:

sudo crontab -e

At the "command" section you can then write the backup command,
for example

Code:

sudo tar -cvf backup.tar project1/trunk

Here's a good manual about using crontab.

Code:

30 23 * * * tar -cvf /home/clx/backup.tar /home/clx/project1

then i type "Ctrl + O" write out ,then exit
i says "crontab:installing new crontab"

but after 23:30 ,i don't see backup.tar in /home/clx

You have to restart the cron deamon.
Try

Code:

sudo /etc/init.d/cron restart

OR

Code:

sudo service cron restart

i've solved it
1 make a script file : backup.sh #(make sure this file has the execute permission)
#! /bin/sh
BDATE=`date +%Y%m%d`
sudo svnadmin dump /home/clx/project1 > /home/clx/backup$BDATE.dump
echo success!

2 in /etc/crontab
0 24 * * * root sudo /home/clx/backup.sh

3 then the backup file backup20110807.dump will be in /home/clx/

4 and recover that backup file :
~$svnadmin create newproject1;svnadmin load newproject1 < backup20110807.dump

but now i want to backup the trunk of my repository.only the trunk,not the whole repository
and the most important ,how to recover the trunk

make back-up of trunk only:

Code:

sudo tar -cf $HOME/project/trunk

To recover:

Code:

tar -xpf $HOME/FileName.tar

$HOME is a path variable and contains de homedir of the user logged in.
i.e.: /home/annielover
