This will create a dated and compressed tar backup once a week, of everything in /usr/local/apache into the /backup/ directory.
This certaintly may be useful considering the amount of worms floating around at the moment (like Santy, which overwrite all php and html files with rubbish)
** this assumes you have your websites in /usr/local/apache as per the
apache/mysql/php compilation howto in this forum, obviously, if they are not in that path, edit the path to point to your websites/code **
(thanks Kobras for advising me here)
Simply do as follows:
Code:
vi /etc/cron.weekly/apache.cron
ok now paste the following into this blank file
Code:
#!/bin/sh
/bin/tar -jcf /backup/apache_backup_`date | awk '{print $2}'`_`date | awk '{print $3}'`_`date | awk '{print $6}'`.tar.bz2 /usr/local/apache/ 1&>/dev/null 2&>/dev/null
save the file and now make it executable
Code:
chmod +x /etc/cron.weekly/apache.cron
ok, create the /backup directory
and test the script (to see that it works)
Code:
/etc/cron.weekly/apache.cron
if all goes well you should see a file like this in your /backup directory
Quote:[root@www root]# ls -alsrxh /backuptotal 140M
140M apache_backup_Dec_29_2004.tar.bz2 4.0K .. 4.0K .
ok that's it ! all done,
now you may want to write another script to 'auto delete' a file if older than two weeks, otherwise your hard disc may soon fill up with backups.

nice anyweb :)
im going to write some "auto delete" tool but i need your help.
how should this tool delete the backup ?
once on at two weeks ?
or ?
the tool should check /backup and if three or more files exist then delete the last (oldest) ones so that there is only two remaining
for example
lets imagine the /backup dir has the following files
Quote:[root@www root]# ls -alsrxh /backuptotal 144M
144M apache_backup_Dec_29_2004.tar.bz2
144M apache_backup_Dec_22_2004.tar.bz2
144M apache_backup_Dec_15_2004.tar.bz2
4.0K .. 4.0K .
then it should 'see' that there are three files, and that 144M apache_backup_Dec_15_2004.tar.bz2 is the oldest, it should then automatically delete 144M apache_backup_Dec_15_2004.tar.bz2
This will mean that you always should have at least TWO weeks worth of backup for your websites.
ok ?

Try this:
Code:
#!/bin/sh
# How many files would you like to keep?
KEEP=2
# Where are the files stored?
BACKUPDIR=./backup
# DO NOT CHANGE ANYTHING BELOW
if [ `ls -1 $BACKUPDIR|wc -l` -gt $KEEP ]; then
i=1
for each in `ls -1t $BACKUPDIR`; do
if [ $i -gt $KEEP ]; then
rm -f $BACKUPDIR/$each
fi
i=`expr $i + 1`
done
fi
This keeps the latest $KEEP files concerning creation time, not filename! This should suit your needs anyways.
thanks z0ny
my script now looks like this
Code:
#!/bin/sh
/bin/tar -jcf /backup/apache_backup_`date | awk '{print $2}'`_`date | awk '{print $3}'`_`date | awk '{print $6}'`.tar.bz2 /usr/local/apache/ 1&>/dev/null 2&>/dev/null
# How many files would you like to keep?
KEEP=2
# Where are the files stored?
BACKUPDIR=./backup
# DO NOT CHANGE ANYTHING BELOW
if [ `ls -1 $BACKUPDIR|wc -l` -gt $KEEP ]; then
i=1
for each in `ls -1t $BACKUPDIR`; do
if [ $i -gt $KEEP ]; then
rm -f $BACKUPDIR/$each
fi
i=`expr $i + 1`
done
fi

the mailing script :)
#!/bin/sh
#setting paths and files
#setting log path
tmp=$tmp
file=apache_backup_`date | awk '{print $2}'`_`date | awk '{print $3}'`_`date | awk '{print $6}'`.tar.bz2 >>$tmp/apachebackup.txt
space=`du -sh $file | awk '{print $1}'`
date=`date`
echo -n "" >$tmp/apachebackup.txt
echo "Hi anyweb, i am the backup tool from linux-noob.com, i got a new backup for you" >>$tmp/apachebackup.txt
echo "the new file is $file and has $space" >>$tmp/apachebackup.txt
echo "the date is $date" >>$tmp/apachebackup.txt
cat $tmp/apachebackup.txt | mail anyweb@linux-noob.com -s 'new backup'
rm -rf $tmp/apachebackup.txt
echo -e "Enjoy"
and of course the best backup is placing that tar file on another computer right?? :)
if you use Debian, take a look at the rsnapshot package. it's a marvellous backup solution.
yes i want to ftp this backup file to another computer on the network once a week (after the latest file is created)
let's say that:-
the ftp address is 100.0.0.2
the port is 21
the user is ftpuser
the password is ftppassword
how can i get the backup script to automagically ftp the 'latest' or just created backup file to the ftp server given the info above ?
i look forward to the answer
cheers

On the LAN I would create a
passwordless SSH login (key secured) and "upload" it via SCP.
