simple automated backup of apache (your websites) - anyweb - 2004-12-29

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

Code:
mkdir /backup

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 ?

simple automated backup of apache (your websites) - anyweb - 2004-12-29

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 ?

cheers

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

Note:

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

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.

simple automated backup of apache (your websites) - anyweb - 2004-12-30

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.
